For inflexible bearings, the largest thing is the rigidity, reliability and rotation accuracy of bearings. Rigid bearings could be preloaded to a definite extent earlier than leaving the factory to guarantee sufficient stress of bearings. The fundamental thing for bendy bearings is the maximum radial deformation of bearings.Harmonic reducer bearings consist of inflexible bearings and flexible bearings two types, inflexible bearings involve four sorts of series, CSG (CSF) series, SHG (SHF) series, CSD series, SHD series, the naming of the reducer; Flexible bearing is called HYR.CSG (CSF) seriesThe outer ring is split into two pieces, and the internal ring is a complete structure. Flange and bearing seat aren't required for installation. It is especially utilized in the output elements of CSG (CSF) collection reducer.SHG (SHF) seriesThe outer ring and the interior ring are integral structure, which has nearly no influence on the performance during installation, and may obtain steady rotation accuracy and torque. It is principally used in the output elements of various forms of retarders of SHG and SHF series.CSD seriesThe outer ring and internal ring are integral structure, the outer diameter size and CSG sort are the same, extra inflexible than CSG variety bearing, mainly utilized in CSD series deceleration output parts.SHD seriesOuter ring and inner ring are integral structure, inner ring with teeth, can immediately mesh with the teeth at the flexwheel, lower top than SHG, saving the installation space of the reducer, mainly used in the output a part of SHD reducer.
