What is the standard of Deep groove ball bearing quality grade

Deep groove ball bearing quality grade, different grades of bearings, the price difference is very large. There are three main criteria for evaluating the quality of deep groove ball bearings:

1. Tolerance of bearings: tolerances and shape tolerances of deep groove ball bearings are expressed by tolerance class. For example, P6 is better than P0, P5 is better than P6, and P5 is twice the price of P6.

2, vibration level: there are Z0, Z1, Z2, Z4 and so on. Z1 group is better than Z0 group, Z2 group is better than Z1 group; or V1 group is better than V0 group, V2 group is better than V1 group, etc.

3. Noise, there is no standard yet. However, for some equipment with special occasions, there are special requirements for noise.

4, bearing material: deep groove ball bearing material and bearing steel, carbon steel, stainless steel, ceramics, bearing prices vary greatly.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. 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.

The STARWEX bearing catalog lists a large range of designs, variants and sizes of deep groove ball bearings. Beyond our catalog offering, the STARWEX Explorer deep groove ball bearings are customizable to offer advantages for applications with specific performance needs.
