Thin wall angular contact ball bearings
This type of bearing is mainly used as the main bearing of the reducer. It has a large contact angle, usually 40°~50°, has high precision and high rigidity, and has an important influence on the torque rigidity of the reducer; the inner and outer rings of the bearing are usually not of the same height. , on the one hand, this is due to the compact structural limitations of the reducer to avoid interference with the bearing during installation, and on the other hand, it is also for the convenience of bearing lubrication and heat dissipation; the bearing cage usually uses a PA66 injection molded crown cage.
Thin wall deep groove ball bearings
This kind of bearing is mainly used in the output part of the reducer, which requires high precision and stable output.
Thin wall tapered roller bearings
These bearings are divided into two types: crank support and main support. The crank support with thin-walled tapered roller bearings is usually smaller and placed on both sides of the crank to support the crank.
Cylindrical roller (needle roller) and cage assembly
This type of bearing has no inner and outer rings. When used, it can be placed in the middle part of the crank. The matching shaft and hole are used as the inner and outer rings and raceways of the bearing, which play an important role in supporting the crank cycloidal wheel. The structure Very simple and compact.
