ZYS Precision Bearing,Bearing Test Machine,Rolling mill bearing

Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
