SHF/SHG harmonic reducer bearing are integral structure, this kind bearing can obtain stable rotation accuracy and torque; it is suitable for SHF (SHG) series harmonic reducers, and can also use in industrial robot arm joints, bionic robots, aerospace equipment, precision machining turntables, solar energy collection platforms, and other occasions requiring high positioning accuracy and high reduction ratio.

The outer ring of the CSF (CSG) harmonic reducer bearing is seperate in two parts, and the inner ring with mounting holes, which is suitable for the CSF (CSG) series of harmonic reducers. The rigid bearings for harmonic reducers are crossed roller structures. According to their use occasions, they are divided into two categories: 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° to each other in a V-shaped raceway. This type of bearing can simultaneously withstand loads in all directions such as axial loads, radial loads, and overturning moments. The bearings have high precision, high rigidity, and composite load-bearing capacity.

The outer ring and inner ring of the CSD micro harmonic reducer bearing are integral, and the outer diameter is the same as that of the CSG type. It has higher rigidity than the CSG type bearing and is mainly used in the output part of the CSD series reducer. Since the inner and outer rings have been processed with mounting holes, there is no need for fixing flanges and support seats, which is more conducive to installation. It is mainly used in robot micro harmonic reducers.

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

Flexible bearings for harmonic reducer are mainly used in harmonic reducer. Harmonic transmission includes three basic components: wave generator, Flexspline,Circular Spline and flexible bearing. Flexible bearings are the core components, and the transmission meets the performance requirements of high deceleration ratio through the elastic deformation of bearings.

In the work of flexible bearing, the inner ring is installed on the elliptical cam, the outer ring is installed on the Flexspline, and the elastic deformation occurs with the rotation of the cam, which not only bears the cyclic stress load, but also bears the alternating stress load.

The hollow rotating platform is supported by a set of ZK hollow rotating platform bearings, which has a simplified structure and enhanced supporting performance. Because the rollers in the ZK hollow rotating platform bearings are staggered at 90 degrees, and the roller diameter is slightly larger than the raceway size between the inner and outer rings of the bearings, there is a preload between the inner and outer rings and rollers of the ZK hollow rotating platform bearings. The servo rotating platform turntable supported by the bearings can withstand various moments such as radial, axial, and overturning, and has high rotation positioning accuracy (up to 0.003mm), accurate positioning without gaps, and rigidity is more than 10 times that of traditional combined bearings, which greatly extends the service life of the rotating platform.
