How to distinguish between precision bearings and ordinary bearings?

How much do you know about precision bearings? Compared with ordinary bearings, what outstanding features does it have?

Jinan Maolei Bearing Co., Ltd. summarizes for everyone that precision bearings and ordinary bearings should be distinguished from the following points:

1. The dimensional requirements are different, and the dimensional deviation (inner diameter, outer diameter, ellipse, etc.) of products with high precision bearings are smaller than that required by products with low precision grades;

2. The required value of rotation accuracy is different. The rotation accuracy (inner radial runout, outer radial runout, end-to-raceway runout, etc.) of products with high precision bearings are stricter than that required by products with lower precision grades;

3. The required values of surface shape and surface quality are different. The surface shape and surface quality of products with high precision grades (surface roughness of raceways or channels, circular deviation, groove shape deviation, etc.) are lower than those with low precision grades. The value required by the product must be strict;

4. The material properties of products with particularly high precision grades are more favorable than those of products with general precision grades.
