introduction： Due to precision micro ball bearings[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 accuracy of itself in1μmwithin，Therefore, it is required to match the machine(shaft、Bearing block、End cover、retainer)High dimensional accuracy and shape accuracy，In particular, the accuracy of the mating surface should be controlled in the same way as that of the bearing
