Product Overview: Robot reducers have the characteristics of high precision, high rigidity, high load, high speed ratio, high life, low inertia, low vibration, low noise, low temperature rise, compact structure, and simple installation. There are two main types of reducers currently used in the field of robot reducers, one is the harmonic reducer and the other is the Rv reducer. Bearings, as one of the most core components in the reducer, are also divided into the following categories according to the reducer, namely, cross roller bearings for harmonic reducers, flexible bearings for harmonic reducers, and angular contact ball bearings for Rv reducers. Cross roller bearings for harmonic reducers include four series, CSG (CSF) series, CSD series, SHG (SHF) series, and SHD series. The naming method adopts the naming of the reducer; the flexible bearings for harmonic reducers are named HYR, and the main bearings of RV reducers are named Rv.
