CSF/CSG Series Harmonic Reducer Bearings (split outer ring, integral inner ring)
The outer ring is divided into two pieces and the inner ring is a whole structure, which does not need flange and bearing seat when installing, and is mainly used in the output part of all kinds of reducers of CSG and CSF series.
Harmonic reducer bearings include rigid and flexible bearings, rigid bearings include four series, CSG (CSF) series, CSD series, SHG (SHF) series, and SHD series, whose nomenclature adopts the nomenclature of the harmonic reducer; flexible bearings include two series, F and 3E.
1. CSF/CSG Series Harmonic reducer bearings Structure
Rolling body is cylindrical roller, distributed in each other into 90 ° vertical arrangement in the V-type raceway. This structure makes a single bearing can simultaneously withstand axial load, radial load and tilting moment and other directions of load, the bearing has a high stiffness, rotational accuracy and composite bearing capacity; this type of bearings in compact shape, the bearings come with mounting holes, easy for customers to install directly, suitable for a variety of different types of harmonic reducer.
2. CSF/CSG Series Harmonic reducer bearings Features
CSF/CSG/SHF/SHG Series Cross Roller Bearing for Harmonic Drive is cross roller structure.According to its application area there are two types( CSF/CSG Series and SHF/SHG Series ).Rolling body are cylindrical rollers which arranged orthogonality,this structure can make one bearing can bear the load from every direction e.g. radial,axial and tilting torque etc. Bearing with high rigidity,rotation accurancy and load carrying capacity. This series bearing has compact appearance,with mounting hole,customer can mount directly,suitable for every kinds of harmonic drives.
3. CSF/CSG Series Harmonic reducer bearings pplications
Harmonic reducer is usually applied on rob9ts, machine tool, and aerospace industries which have higli requiremets on harmonic reducer precision7 rigidity, and load capacity. So it has high requirements -ts:
harmonic reducer parts machining precision rd mountng precision and also to bearings. For rigid bearing the most important are the bearing rigidity, reliability, and rotation precision. Rigid bearing usually has some prelad before leaving the factory in 94-der to giarantee bearing has enough rigidity. The maximum (radial defdrmation is very important to flexible bearing.)
