The reducer is a power transmission mechanism. The speed converter of the gear is used to reduce the rotation number of the power source to the required rotation number, and obtain a larger torque. The reducer bearing plays a role in supporting the gear shaft or connecting rod between the rotations, because the cylindrical roller bearing can obtain a continuous and stable supporting torque within the effective size range, and has a certain amount of axial movement. Nu NJ type cylindrical roller bearings are usually used, which are installed at the support positions at both ends of the shaft.
The single row and double row non outer ring bearings produced by ASAL Bearing are mostly used in the planetary reducer gearbox. For example: RSL series, CPM series, F-series, etc.
