Precision bearing according to the classification standard of the ISO can be divided into: P0, P5, P6, P4, P2.
Higher level in turn, which is suitable for ordinary precision P0, other grades are precision level.
Of course, different classification standard, the different types of bearings, their classification method is different, but the significance is one to.
Precision bearing using the performance requirements of revolving beating with high precision, high speed rotation and friction and low friction change.
Precision bearings and plain bearing should to distinguish from the following points: 1, the required values are not the same size, high precision grade product size deviation (
Inside diameter, outside diameter, elliptical, etc. )
Lower than the accuracy grade of the value of the product requirements to small;
2, rotation accuracy requirements are different, the product with high precision grade the rotation accuracy (
Radial runout, outer diameter to the beat, end face a race to beat, etc. )
Lower than the accuracy grade of product value to strict;
3, surface shape and surface quality is not the same as the required value, high precision grade of the surface shape and surface quality (
Race or surface roughness of the channel, circular deviation, furrowed deviation, etc. )
Lower than the accuracy grade of product value to strict;
4, particularly high precision grade products its material is better than general precision grade products of material performance.
