    About CSF harmonic drive reducer bearings

    Harmonic drive speed reducer is also called strain wave drive, its main components including wave generator, flex gear, ring gear, and crossed roller bearing. As one of the most important components of the strain wave drive, the quality and service life of the crossed roller bearing (output bearings of harmonic reducer) are essential. The cross-roller ring of harmonic reducer gear units is very different in shape and structure from the ordinary crossed roller bearing. Firstly the mounting holes, especially the inner ring of the CSF|CSG series harmonic reducer bearing, tapped holes of different PCD & specifications are placed on the inner ring from the outside to the inside. Secondly, there is a big difference in the heat treatment process. Although the materials are all made of GCr15 bearing steel, BRS Bearing adopt a special technic during the heat treatment processing of inner and outer ring, in order to ensure the accuracy of each positioning hole and mounting hole.
