Product categories of cross roller bearings for harmonic reducers

Crossed roller bearings for harmonic reducers are divided into two categories according to their use occasions: split outer ring, integral inner ring, and both outer ring and inner ring are integral. The rolling elements are cylindrical rollers, which are arranged vertically at 90° in the V-shaped raceway. Bearings with this structure can simultaneously bear loads in various directions such as axial load, radial load and overturning moment. The bearings have 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. Their naming method adopts the naming of reducers.

CSG (CSF) type

The outer ring is divided into two pieces, and the inner ring is an integral structure. Flanges and bearing seats are not required during installation. It is mainly used in the output part of CSG and CSF series reducers.

CSD type

Both the outer ring and the inner ring are integral structures. The outer diameter size is the same as that of the CSG type. It has higher rigidity than the CSG type bearings and is mainly used in the output part of the CSD series reducer.

SHG (SHF) type

The outer ring and inner ring are both integral structures, which have almost no effect on performance during installation, and can obtain stable rotation accuracy and torque. They are mainly used in the output parts of SHG and SHF series reducers.

SHD type

The outer ring and inner ring are both integral structures, and the height is lower than that of SHG, which saves the installation space of the reducer. It is mainly used in the output part of SHD reducers.
