The roller of a cylindrical roller bearing is usually guided by two edges of a bearing ring. The cage roller and the guide ring form an assembly, which can be separated from another bearing ring. It belongs to a separable bearing.

The bearing is easy to install and disassemble, especially when the inner and outer rings are required to be interference fit with the shaft and housing. This kind of bearing is generally only used to bear radial load. Only single row bearing with inner and outer rings with retaining edges can bear small steady axial load or large intermittent axial load.

Main applications: large motors, machine tool spindles, axle boxes, diesel engine crankshafts, automobiles, transformer boxes, etc.
