Ball bearings are important Support parts in the frame of platform, their performance affects the precision, reliability and stability of the platform system dircetly. In this paper, the mechanism of friction moment of low speed ball bearings are analysed and tested,three factors affecting the starting friction moment are approached, and some methods of mitigating the friction moment are presented. In order to improve the performance of the ball bearing, retainer made from high precise and porous materials and dilute lubricating oil should be used.
