Crossed roller bearings for harmonic reducers are divided into two types: the outer ring split and the inner ring integrated according to the application occasion. The outer ring and the inner ring are two types of the whole. The rolling elements are cylindrical rollers, which are arranged vertically at 90° in the V-shaped raceway. The bearings of this structure can simultaneously bear axial loads, radial loads and overturning moments. The bearings have high precision, high rigidity and composite load-bearing capacity.
There are four series of crossed roller bearings for harmonic reducers, CSG (CSF) series, CSD series, SHG (SHF) series, and SHD series, and the naming method adopts the name of the reducer.
CSG (CSF) type
The outer ring is divided into two pieces, and the inner ring is an integral structure. No flange and bearing seat are required for 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 have integral structure, and the outer diameter is the same as the CSG type bearing, which has higher rigidity than the CSG type bearing, and is mainly used in the output part of the CSD series reducer.
SHG (SHF) type
Both the outer ring and the inner ring are integral structures, which have almost no impact 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 the inner ring are integral structures, and the height is lower than that of SHG, which saves the installation space of the reducer, and is mainly used in the output part of the SHD reducer.
