Cylindrical Roller Bearing
Characteristics of cylindrical roller bearing:
The rollers of cylindrical roller bearings are usually guided by two flanges of a bearing ring. The cage rollers and the guide ring form a combination that can be separated from the other bearing ring and belong to separable bearings.
This type of bearing is easy to install and disassemble, especially when the inner and outer rings are required to have interference fits with the shaft and housing.
This type of bearing is generally only used to bear radial loads. Only single-row bearings with flanges on both the inner and outer rings can bear smaller constant axial loads or larger intermittent axial loads.
Main uses: large motors, machine tool spindles, axle boxes, diesel engine crankshafts, automobiles, tractor gearboxes, etc.
Classification of cylindrical roller bearing:
