Crossroller bearings for harmonic reducers are divided into two major categories according to application scenarios: split outer ring with integral inner ring, and integral outer ring with integral inner ring. The rolling elements are cylindrical rollers arranged perpendicularly to each other at 90° inside Vshaped raceways. Bearings of this structure can bear multidirectional loads including axial loads, radial loads and overturning moments, featuring high precision, high rigidity and composite loadbearing capacity.
CSG (CSF) Specialpurpose Bearing for Harmonic Reducers (Split Outer Ring, Integral Inner Ring) The outer ring is split into two pieces while the inner ring adopts an integral structure. No flange or bearing housing is required for installation. It is mainly applied to the output sections of CSG and CSFseries reducers.
CSD Specialpurpose Bearing for Harmonic Reducers (Integral Outer Ring, Integral Inner Ring) Both outer ring and inner ring are of integral structure. It shares the same outerdiameter dimension with CSGtype bearings yet delivers higher rigidity, and is mainly used for the output sections of CSDseries reducers.
SHG (SHF) Specialpurpose Bearing for Harmonic Reducers (Integral Outer Ring, Integral Inner Ring) Both outer ring and inner ring are of integral structure. Installation barely affects its performance, enabling stable rotational precision and torque. It is mainly applied to the output sections of SHG and SHFseries reducers.
SHD Type (Integral Outer Ring, Integral Inner Ring) Both outer ring and inner ring are of integral structure. It has a lower height than SHG type to save installation space for reducers, and is mainly used for the output sections of SHD reducers.
