The structure of Cylindrical Roller Bearings is the inner ring and outer ring which can be separated. Cylindrical Roller Bearing without sidewall in inner nor outer rings can be used as a free-end bearings because Its inner and outer rings can move relative to the axial. Cylindrical Roller Bearing which has double sidewalls in either inner or outer ring and single sidewall in the other side, can bear a certain degree of axial load. Usually we use stamping steel retainer or lathe-manufactured Copper Alloys retainer. However, we also use polyamide forming retainer.
