For inflexible bearings, the biggest factor is the rigidity, reliability and rotation accuracy of bearings. Rigid bearings can be preloaded to a definite extent before leaving the factory to ensure enough tension of bearings. The major factor for flexible bearings is the maximum radial deformation of bearings.Harmonic reducer bearings encompass inflexible bearings and versatile bearings two types, rigid bearings involve 4 kinds 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 inner ring is a complete structure. Flange and bearing seat are usually not required for installation. It is especially utilized in the output parts of CSG (CSF) collection reducer.SHG (SHF) seriesThe outer ring and the interior ring are integral structure, which has nearly no impression on the performance throughout installation, and might achieve 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 kind bearing, mainly utilized in CSD series deceleration output parts.SHD seriesOuter ring and inner ring are integral structure, inside ring with teeth, can straight mesh with the enamel at the flexwheel, decrease height than SHG, saving the installation area of the reducer, chiefly used in the output a part of SHD reducer.
