The miniature taper roller bearing mainly use in RV reducers , it's one of the key components of the RV reducers. It is designed with compact dimensions and consists of an inner ring, an outer ring, rollers, and a cage. It can be used in a compact RV reducer , meeting the requirements of RV reducer for bearings to bear radial and axial combined loads, high rigidity, impact resistance, wear resistance, impact resistance, and long service life.

The high precision angular contact ball bearings for the RV reducer are generally slim thrust ball bearings with a 40° contact angle. They are used in pairs, high capacity, high precision, high rigidity, stable operation, and bear all the external loads of the RV reducer. This is the main positioning bearings. The structural characteristics and precision ensure high working positioning accuracy, low vibration, and large reduction ratio for industrial robots under specific working conditions.
