introduction：Bearings are mainly observed during testing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The rivet head is not crooked、The position of the slack weld is not correct。Cage welding is good or bad。Welding points are not too small，Some welding is not strong，Or excessive welding caused by the ball and other problems。Its all testingNTNbearing[NTNbearing:NTN A variety of bearing products，therefore 0.01 It is produced by high-precision machining and testing technology in micrometers，From the requirements of both high performance and low cost of ordinary household appliances，Aerospace rockets that can still perform their bearing functions normally in harsh working environments are required， NTN Bearings in all walks
