Crossed roller bearings for harmonic reducers are divided into two categories according to their application occasions: split outer ring, integral inner ring, and integral outer ring and inner ring. The rolling elements are cylindrical rollers, which are arranged vertically at 90° to each other in a V-shaped raceway. This type of bearing can simultaneously withstand loads in all directions such as axial load, radial load and overturning moment. The bearing has high precision, high rigidity and composite load capacity. Crossed roller bearings for harmonic reducers include four series, CSG (CSF) series, CSD series, SHG (SHF) series, and SHD series, and their naming method adopts the naming of reducers.

The CSG (CSF) type outer ring is divided into two pieces, and the inner ring is an integral structure. No flange and bearing seat are required during installation. It is mainly used in the output part of CSG and CSF series reducers.
