problems consumers rated the highest, angular contact thrust ball bearing accounted for 10.1%, mainly reflected in the plate is thin, key sensitivity; the noise problem is very serious, bad review accounted for 3.7%; workmanship bad review mainly concentrated in the sealing is poor, rough surface, screw not firm, 3.4%. Therefore, enterprises should pay attention to strengthen the quality of products, improve the comprehensive competition strength.

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.
