What is a Bearing? Basic study

The current form of bearing was developed at the end of the 19th century. It was originally handmade.
Nowadays, bearings are one of the most commonly used mechanical parts because their rolling motion makes almost all movements easier and helps reduce friction.

Bearings have two key functions:

They transmit motion, that is, they support and guide components that rotate relative to each other
They transmit power

Rolling bearings and sleeve bearings
In a bush or sliding bearing, the shaft and the bearing move in opposite directions on the sliding surface. In contrast, the two close parts of a rolling bearing-the inner ring and the outer ring-are separated by rolling elements. The friction generated by this design is much smaller than that of sleeve bearings.

Radial bearing and axial bearing
Bearings can transmit loads in the radial or axial direction (thrust), and in many cases, both radial and axial loads are transmitted.

Both designs can provide ball bearings or roller bearings. The choice of bearing design depends on the application in question.

Component

Bearings usually consist of the following components:

• Two rings or discs with raceways
• Rolling elements in the form of rollers or balls
• A cage that keeps the rolling elements separate and guides them

Inner ring/outer ring
The inner and outer rings are usually made of special high-purity chromium alloy steel. This material has the necessary hardness and purity-both important factors for high load ratings and long service life.

The raceway is hardened, ground and ground.

Special materials such as ceramics and plastics are also used. Although plastics cannot withstand extremely high temperatures, they are much lighter than steel. This makes them invaluable in industries where every gram is important (such as the automotive industry).

Scroll element
The rolling elements can be balls, rollers, cones, balls or needles. They are usually made of special high-purity chromium alloy steel. Special materials such as ceramics and plastics are also used.
The rolling elements roll on the specially designed ring or disk raceway, and are kept separate and guided by the cage.

Bearings are carefully designed and precision-manufactured components that enable the machine to move at extremely high speeds and easily and efficiently withstand huge loads.

Bearings must be able to provide high accuracy, reliability and durability, and be able to rotate at high speed with minimal noise and vibration.

Applications of bearings include automobiles, airplanes, computers, construction equipment, machine tools, DVD players, refrigerators and ceiling fans.

If something twists, turns, or moves, it may have bearings in it.

Bearing type and application

There are many different bearing types, and each type has special characteristics suitable for specific applications. The following are the four most common bearing types:

Ball Bearings:

• The rolling function is provided by the ball
• Low friction, high speed, light to medium load
• Lightweight and general machine applications

Commonly found in applications such as fans, roller blades, wheel bearings, and under the hood of automobiles.

Cylindrical and needle roller bearings:

The rolling function is provided by a certain type of cylinder. It can also be called a needle bearing (the length is much larger than the diameter)

• Low friction, medium to heavy radial load

Usually found in general mechanical applications, including gearboxes and transmissions, machine tools and construction equipment.

Tapered Roller Bearings:

Tapered roller bearings are used for combined axial and radial loads, for example in truck wheel applications

Generally bear radial and axial loads in heavy industry, truck and wheel applications. Some examples are manual transmissions, gearboxes, power generation and other process equipment.

Spherical roller bearing:

• Roller bearings with barrel rollers.
• Medium friction, medium to heavy load and misalignment ability
• Typically used for ultra-high load applications where the shaft and housing are misaligned.

How to tell if front wheel bearing is bad?

Front Wheel bearing is a key part of the wheel hub assembly that connects the wheel to the axle. It is a set of steel balls bearings or tapers held together by metal rings. Wheel bearings are essential to the operation of the vehicle and the normal function of the wheels, tires and wheels. It can reduce friction and keep the car running smoothly on the road. Although you have taken the car to the local car repair shop and Mehndi said they need to check the front wheel bearings, you are not sure what it is. Does that matter? Do you need repairs? Well, here, we will subscribe what a wheel bearing is and how the sound of the front wheel bearing in your car sounds

First, What is the front wheel bearing?

Wheel bearings are a set of steel balls that are held together by metal rings called ascending. They help the wheels to spin quickly and smoothly and minimize headline friction to reach the correct speed and smoothly glide. They are used in various cars, trucks, cars, coupes, bicycles and airplanes. There is front wheel bearing and rear wheel bearing.

On your vehicle, they are usually located on a metal shaft and tightly mounted inside the wheel hub, which is a hollow metal block in the center of the wheel. The hub is then responsible for fixing the lug bolts used to connect the tire to the wheel. Then press the wheel bearing into the hub from the back of the front wheel bearing.

The signs of wheel bearing wear vary in severity. Some may be difficult to detect, leading to damage and corrective actions must be taken. The time frame for damage is related to the driving conditions and/or the mechanical operations followed during installation. Noise is a typical sign of damage to wheel bearings or hub bearings. The following are some signs of wheel bearing wear or wheel end damage:

As you pass through, when you start to hear a loud noise under the hood of a car, you may automatically think it is an exhaust leak or the car will break at any time. But have you considered the possibility of damaged or almost damaged wheel bearings?

Wheel bearings are essential to the operation of the vehicle. More precisely, wheel bearings are essential for the proper functioning of the wheel hub, tire and wheel assembly. Wheel bearings allow the wheel hub assembly to move and rotate without friction, thereby providing smooth tire and wheel rotation. When the wheel bearing is damaged, you will notice some symptoms.

Listen carefully The most common and usually the most recognizable symptom associated with wheel bearing damage is noise from the wheels or tire area of ​​a moving vehicle. You may mistake it for engine noise, but when you listen carefully, you may hear a hoarse or harsh sound as the vehicle accelerates. Since the wear frequency of wheel bearings is not known to be so high, it is usually suspected to be noise, and the problem is ignored.

Does your car feel loose? When you hear professional drivers talking about “loose” cars, you may not know what it means. It usually refers to the steering system of the vehicle, which may include wheel bearings. Loose wheels, or wheel slip, is another common symptom of wheel bearing damage. As the bearings begin to wear, they become loose in the hub and main shaft, which makes your vehicle feel loose when turning.

Are you turning, or is the car driving in its desired position? When the wheel bearing corrodes or enters the pit, the smooth outer lining disappears and the vibration is transmitted to the tire, which feels like the tire is “pulling” to one side or the other.

What about your tires? We all know the importance of rotating tires to promote uniform wear, but did you know that damaged wheel bearings can also cause uneven tire wear? Loose wheels and vibrations reverberating on the wheels can cause uneven tire wear, which means you are more likely to have to invest in new tires as soon as possible.

What caused the front wheel bearing to be damaged?

When the bearing cools down after use, the shrinking metal, air and lubricant will cause a vacuum, which needs to be held by the seal. If the gasket cannot maintain the vacuum, the bearing or hub will suck in any external debris and water. In some places, it is almost as serious as excess salt or seawater on the front wheel bearings.

If you notice that the front wheel bearings are bad, the driver may notice a little wandering or loose steering wheel, or noise from near the wheels. The noise may change when the wheels turn or when the front wheel bearing noise disappears at certain speeds.

When the front wheel bearings are worn, it is usually due to insufficient lubrication, improper installation or incorrect adjustment. In order for wheel bearing repair to be successful, you must first determine why a bearing failure occurred in your car before.

The most common failure mode of the front wheel bearing is that the bearing on the passenger side of the vehicle fails first. The front bearing on the passenger side is exposed to the most still water in the gutter. If the driver’s bearing fails first, it may cause a complete failure.

If the front wheel bearing overheats, the hot lubricant will decompose and may cause scratches and corrosion on the bearing surface. In addition, water and other elements can also cause this situation, which can cause problems when driving.

What are Tensioner bearings and Idler Bearings?

How to purchase the right tensioner bearings and idler bearings from a good manufacturer or supplier from China or other countries? How to find a good factory in China. Before, you need to learn about the basic knowledge of tensioner and idler bearings.

This bearing is located at the front of the internal combustion engine. It provides tension to the belt from the crankshaft to the camshaft, air compressor, alternator, water pump, and power steering pump. Due to the continuity of the engine used, it must deal with high temperatures, belt vibration, and high-speed rotation in order to change the direction of the belt. The design of these bearings is different from the specifications of ordinary deep groove bearings.

Tighten the bearing to apply tension to the drive belt and prevent slack. The idler bearing will affect the direction angle change of the belt running, or affect the contact width with the pulley.

Timing belts and auxiliary belts are equipped with idler bearings, and pulleys and brackets are installed on the idler bearings.

Among them, in the timing belt mechanism, sometimes the type with a hole in the inner ring or a bracket for tension adjustment is called a “tension bearing”, and the type without an adjustment mechanism is sometimes called an “idler bearing” “.

The auxiliary idler bearing is also used in the auxiliary drive belt mechanism.

Features

• By adapting them to harsh driving environments and harsh weather conditions, they have improved their ability to prevent penetration of muddy water and dust.
• Use reinforced resin pulleys with excellent heat resistance and chemical resistance to significantly reduce weight.
• Reliability can be improved by using materials that work under high-speed rotation and high-temperature conditions (such as seals and grease).

Structure

The tensioner and idler bearing are composed of basic components such as inner ring, outer ring, cage, grease, and seals. A pulley can be added to adjust the rotation ratio. You can add a bracket to adjust the position to increase tension. The race is one of the components of the bearing. It has a groove track that allows the ball to be positioned. Outer race and inner race formed a set. The inner seat ring is located on the subassembly, and the outer seat ring is located on the housing. A pulley can be added to the outer ring to provide a timing belt system with a designed speed. The rolling element is the “ball” that runs between games. The retainer moves with the ball, holding the single ball in place. Grease also has an important role in reducing friction, and the oil seal can hold the grease and prevent foreign matter from entering.

Wheel Bearing
A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of ball bearings or tapered bearings, held together by a metal ring, which enables the wheel to rotate smoothly with a minimum of friction. Wheel bearings are safety critical components designed to sustain radial and axial loads caused by gravitation, acceleration, breaking & cornering forces. They need to be replaced when they stop working properly.
How long is wheel bearing lifespan?
Wheel bearings have an average lifespan of 136,000 to 160,000 km (approximately 85,000 to 100,000 miles). This is only a rule of thumb though, the actual lifespan of a wheel bearing also depends on the quality of the wheel bearing and the operating conditions.

In that case it is important to find the right and good quality wheel bearings for your car. You can have a look at the knowledge about the 9 best bearing brand, and how to choose a good Chinese supplier

What is the most complicated auto repair DIY?

What is the most difficult of the auto repair work? Wheel bearing, Wheel hub bearing, engine, timing, air conditioner bearing, clutch release bearing, etc.? Nowadays, fewer and fewer people choose to repair their cars, and wisely choose to hand their cars to car maintenance technicians. This is partly due to the complexity of cars in the world today, and cars 30 years ago can be repaired by almost any convenient owner with tools and a little car knowledge. After investigating various recommendations from auto technicians, these are widely regarded as the most difficult car repairs. If you decide to take an apprenticeship as an auto mechanic, you may want to keep these four challenging maintenance tasks in mind in the future.

1. Replacing an Engine

People who have experienced the pain of replacing an engine, whether it is ordinary man or a qualified car technician, will say that this is the biggest challenge of all cars. Cars are expensive, so it is feasible to replace the engine instead of buying a brand new car. In many cases, using the company’s remanufactured engine to power the car is the most cost-effective long-term option for the vehicle. Although the cost may be between 2,000-4,000 US dollars, this only accounts for 10-20% of the cost of buying a new car. However, repairing is not as simple as installing a new engine (it is a difficult process in itself). Depending on the mileage of the old engine, you may need to replace some connecting parts that have accumulated mileage, such as the gearbox.

2. Transmission

The transmission is arguably the most complicated part of a car. This is the heart of most vehicles. The transmission contains thousands of complex parts, which play a very important role in moving the car forward or backward. Due to its complexity, the transmission can hardly be repaired or replaced by an ordinary backyard mechanic. However, many people try to repair the transmission themselves, usually with disastrous consequences. Even changing the transmission oil in a car is complicated, and special procedures must be performed by a mechanic.

As we all know, the repair of transmission is expensive, so mechanics may find that some customers are unwilling to solve these problems until they are in a crisis stage. Leaking transmission oil is the easiest way to understand some incorrect phenomena. The problem of manual shifting may be caused by insufficient transmission oil or improper adjustment of the shift cable or clutch linkage. Overheated fluids, gear slippage and terrible drag clutches all require professional attention.

3. Timing Belt

If you have owned the car long enough, you will eventually need to replace the timing belt. Moreover, although many people try to replace themselves, it is never recommended. This is because A) the timing belt is an important part of keeping the engine running, and B) it will be necessary to disassemble about half of the car’s engine to reach the timing belt that needs to be replaced. Even if you successfully replace the timing belt, it is difficult to assemble the engine perfectly. The slightest mistake can cause long-term and irreparable damage to your car engine.

4. Replacing suspension components.

It looks like suspension parts such as struts, arms and bushings that are easy to replace, but there are many ways to make this repair that can lead unskilled people astray. Beginners may not understand the huge force in compression coil springs (for example, when replacing struts); they may do things in the wrong order; otherwise they may not realize that part of the suspension supports the front subframe and engine. For home mechanics, it is impractical and costly to have some special equipment (such as wheel alignment brackets) required to complete the work correctly. For typical suspension maintenance, the labor cost is not high, so You may leave them to professionals as well.

5. Clutch

As a “worn” part in the vehicle, depending on your operating conditions, the clutch may need to be replaced every 30,000 kilometers. A less common reason for clutch maintenance is that improper assembly can cause oil leakage. Repairing the clutch involves disassembling the gearbox, which is mainly what makes repairs so difficult

6. Spark Plugs

The spark plug is responsible for igniting the gas vapor and running the engine. Although the maintenance cost of the spark plug is not high, it is a necessary maintenance because the spark plug is often worn out during use. The difficulty lies in their small size, coupled with the fact that they are stuck in hard-to-reach car areas. Some engine compartments are more crowded than others, so depending on your car, this may end up being just a simple repair

7. Wheel bearing

Wheel bearings are essential components that allow the wheels on the vehicle to rotate freely with as little friction as possible. Wheel bearings are ball bearing rings fixed in a ring, which is called a “race”. This simple and clever design helps you turn the wheel with minimal friction. The wheel bearings are a set of steel balls, which are contained in a metal shell called the track, located in the hub of the wheel. If you hear a moan or hum while driving, it is likely that one of the wheel bearings of your vehicle has started to malfunction.

Replacing your own wheel bearings is considered an intermediate job that can be done at home, but requires some special mechanical tools. The steps provided below are summarized to cover the three most common wheel bearing types on most vehicles. Before starting repairs, be sure to obtain the vehicle’s repair manual and determine the type of wheel bearing that the vehicle is equipped with.

How long does it take to replace a wheel bearing?

Wheel bearing are essential to the operation and high quality of your car. More importantly, wheel bearings are essential for the optimal work of tires, tires and wheel assemblies so that they work together to achieve optimal performance. Wheel bearings are responsible for frictionless movement and rotation, providing smooth tire sliding on the road. The type of wheel bearing is different-therefore, it is possible to change the time to replace the wheel bearing.

Symptoms of Bad Front and Rear Wheel Bearings

As we all know, wheel bearings are key components of automobiles, and both front and rear wheels use hub bearings. Each individual wheel has its own wheel bearing, which means that one wheel bearing may wear out over time or become more damaged than the other three options. One wheel bearing may wear out while the other wheel bearing is in good condition, which changes the time it takes to replace the wheel bearing.

Single replacement of wheel bearings is the reason why you do not have to replace every wheel bearing when you visit a local mechanic. Many mechanics may try to get you to perform all four operations at the same time so that they can make more money on procedures and labor costs, but this is usually not necessary, but just a way for them to get more money at once. When making sure that the mechanic performs the procedure, you ask how long it will take to replace the hub bearing.

You can pay attention to certain signs and symptoms to indicate the prevalence of wheel bearing damage on cars. If you don’t know the signs and symptoms, the technician will know what to look for and will tell you how long it will take to replace the wheel bearings. To give you an idea of what to look for, we have listed the top 5 serious symptoms of wheel bearing defects.

·       Uneven Tire Wear

Due to overdriving, driving on uneven ground, certain driving characteristics or poor wheel alignment, uneven tire wear is common. When wheel bearings wear over time, they tend to wear more unevenly than other tires and wheels. Bearings with such wear will cause abnormal tire wear, resulting in uncomfortable and shaky driving.

In a typical driving situation, when tires are worn and worn, they will wear at the same time only in typical driving use. If the tires wear unevenly and they wear unevenly, it may be due to damaged wheel bearings. If only one wheel bearing is faulty, this may affect the time required to replace the wheel bearing.

In addition, other problems can also cause wheel bearing damage and uneven tire wear, such as poor wheel alignment, tire imbalance, and dangerous driving behavior.

·       Grinding Noise

Another common symptom of wheel bearing damage or wheel bearing damage is that the tire makes a loud rubbing noise during use. The location of the friction sound can indicate which wheel bearing is damaged and can let you know how long it will take to replace the wheel bearing. When a wheel bearing loses lubrication and accumulates too much heat, it usually produces a frictional sound, which leads to excessive friction and internal heat.

Grinding two pieces of metal (usually metal on metal) together will generate grinding noise and cause excessive friction in the grinding wheel area. Generally, due to uneven wear of the wheel bearings, you may only hear the sound from a single wheel. If you notice a lot of noise when changing gears or turning the steering wheel, it may be a clear sign that the wheel bearings are damaged and you need to study how long it takes to replace the wheel bearings.

·       Steering Wheel Vibrates

If the wheel bearings deteriorate severely over time, you will notice excessive steering wheel vibration and shaking while driving. When you are driving at a lower speed, you may notice such shocks and vibrations, but the problem will be exacerbated when you try to accelerate the car, whether it is driving on the highway, towing heavy objects, or driving uphill.

Many people may think that this symptom is related to the imbalance of the vehicle’s tires, but you should take the car to a mechanic to have them diagnose the problem and make sure that the wheel bearings and tires are faulty. In order to determine whether the shaking is caused by the wheel bearings, the mechanic may recommend that you replace them, which may lead you to ask how long it will take to replace the wheel bearings.

·       Vehicle Pulls To One Side

When wheel bearings wear over time due to prolonged use or harsh driving conditions, they may corrode or dent. If the smooth lining on the wheel bearing breaks and no longer exists, the rough surface of the bearing can cause vehicle vibration. In this case, you need to study how long it takes to replace the wheel bearings.

When you try to drive straight on the road, you may also encounter the situation where the car pulls to one side. This situation is more common when you step on the brakes, because the car will accidentally drive to the side. Although this is a common signal that indicates a problem with your brake rotor or caliper, the actual root cause may be the wheel bearing itself. If the mechanic determines that this is the cause of the pull, he needs to investigate how long it will take to replace the hub bearing at the local auto repair shop.

·       Excess Wheel Wobble

Although this excess clearance on the wheel is troublesome and difficult to diagnose, it still needs to be ruled out when looking at the wheel bearings of a car. To diagnose this problem, you should take the car to a professional so that they can use a hydraulic lift or jack stand to lift the car into the bottom of the vehicle.

When the car is lifted from the ground, the mechanic will need to grab a wheel and swing it back and forth to see how much movement is in the wheel. The mechanic should repeat this process for each wheel on the other axle to determine how long it will take to replace the wheel bearings.

If the wheel wobbles or moves too much when the technician shakes the wheel, it is likely to be the culprit of the wheel wobble. In this case, you need to ask the mechanic how long it takes to replace the wheel bearings in his shop.

Cost To Replace Wheel Bearings

When you determine that wheel bearings are causing problems in your car, you may decide how long it takes to check and replace wheel bearings. In this case, it is also important to check the total replacement price for each type of wheel bearing on your vehicle.

·       Front Wheel Bearings

The front wheel bearings are connected to the steering knuckle arm assembly and axle assembly of the car, thus showing that they are a key part of the vehicle’s function. These bearings have a service life of several years and do not need to be replaced, but certain conditions can cause these front wheel bearings to be damaged over time. The cost of replacing the two front wheel bearings is between US$255 and US$500 and may affect the time required to replace the wheel bearings.

From the perspective of the price breakdown of the front wheel bearings, the average price of the parts used for this repair is 120 US dollars and 200 US dollars. In addition, labor costs are even more expensive than parts costs, ranging from $150 to $300. The exact labor cost will depend on where you take the car, the type of store you take the vehicle to, and the geographic location of the store.

If you just want to replace one side of the wheel bearing, then these costs will be divided into half of the total price of a single front wheel bearing replacement. The cost of a replacement is between $140 and $240, the price of parts is between $70 and $120, and the average labor price is between $80 and $150.

·       Rear Wheel Bearings

Compared with the front wheel bearing, the replacement cost of the rear wheel bearing is lower, and it takes less time to consider the time required to replace the wheel hub bearing. However, the price of this patch depends on the make and model of the car that needs to be replaced. The replacement cost of a complete rear wheel bearing is usually between $250 and $470 and will affect the time to replace the wheel bearing. The total cost of parts is between 120 and 100 dollars, and the total labor cost is between 150 and 300 dollars.

If you only need to replace the rear wheel bearing on one side, you only need to have these costs. The cost of the entire work is between US$120 and US$240, the cost of parts is between US$50 and US$90, and the cost of labor is between 80 and 150 dollars. The decision whether to replace a set of wheel bearings or a complete set of bearings will affect the time to replace the wheel bearings.

·       Rear Hub Bearings

Certain types of vehicles use rear wheel hub mechanisms instead of front wheel bearings. In this system, the wheel bearings are packaged in the wheel hub and installed as a single integral unit instead of separate components, which may affect the time required to replace the wheel bearings. In addition to affecting how long it takes to replace the hub bearing, this also makes the hub assembly more expensive than just replacing the hub. For this, you can pay $500 to $900 to replace these two components.

Types of Wheel Bearings

You should remember the different types of wheel bearings. You will usually find some common types in cars-

·       Ball Bearings

Ball bearings are the most common wheel bearings on the market today, and they are also the most versatile. This type of wheel bearing can absorb different types of loads to absorb impact and have sufficient performance. In order to determine the turning pressure that the ball bearing can use, you need to determine the thrust load and radial load to understand how long it will take to replace this type of wheel bearing.

·       Roller Bearings

The Roller bearing is a special kind of wheel bearing, which can usually be found in various types of cars on the market. The only disadvantage of using this type of wheel bearings is that they are not as versatile as typical ball bearings, but they perform well in handling heavyweight items. This feature of rolling bearings can change the time it takes to replace wheel bearings.

·       Precision Ball Bearings

This type of wheel bearing is used in high-performance vehicles and needs, thus changing the time required to replace wheel bearings. These precision ball bearings have the ability to reduce excessive heat generated by friction and material friction together. The speed of precision ball bearings is higher than that of conventional bearings and has been widely used for thrust and radial loads of vehicles.

·      Tapered Roller Bearings

Conventional wheels in vehicles will have tapered roller bearings, and when the thrust load is high, these bearings will reduce friction, excessive movement, friction, and heat. When turning the car, tapered roller bearings can prevent parts from grinding and affect the time required to replace the hub bearing.

Conclusion

As we all know, wheel bearings are the key components of automotives, and are essential to the normal operation, function and performance of vehicles. Since wheel bearings are vital to the function of tires and wheel components, they must be replaced and replaced in time. In addition, different types of wheel bearings are installed in your vehicle, which changes the time to replace wheel bearings.

What is deep groove ball bearings

Deep groove ball bearings are the most widely used bearing type. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

Deep groove ball bearings are a more common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. The deep groove ball bearing types are single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without sealing structure.

The sealed deep groove ball is divided into dust-proof seal and oil proof seal. The dust seal cover material is stamped from steel plate, which is simple to prevent dust from entering the bearing raceway. The oil-proof type is a contact type oil seal, which can effectively prevent the grease inside the bearing from overflowing.

The single row deep groove ball bearing type code is 6, and the double row deep groove ball bearing code is 4. The utility model has the advantages of simple structure, convenient and is a kind of bearing which is relatively popular in production and widely used.

Deep groove ball bearings are mainly subjected to radial loads and can also withstand radial loads and axial loads. When it is only subjected to radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed.

According to the size and size of deep groove ball bearings can be divided into:

• Miniature bearings—-bearings with a nominal outside diameter range of 26mm or less;
•  Small bearings—-bearings with a nominal outer diameter range of 28-55mm;
•  Small and medium-sized bearings—-bearings with a nominal outer diameter range of 60-115mm;
• Medium and large bearings—-bearings with a nominal outer diameter range of 120-190mm
• Large bearings—-bearings with a nominal outer diameter range of 200-430mm;
• Large bearings—-bearings with a nominal outer diameter range of 440mm or more
