Cylindrical roller bearing


The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling element and the retaining edge of the ferrule is small, which is suitable for high-speed rotation. According to whether the ferrule has retaining edge or not, it can be divided into single row cylindrical roller bearings such as Nu, NJ, NUP, N and NF, and double row cylindrical roller bearings such as NNU and NN. The bearing is a separable structure of inner ring and outer ring.

Cylindrical roller bearing with inner ring or outer ring without retaining edge, whose inner ring and outer ring can move relatively axially, can be used as free end bearing. A cylindrical roller bearing with double retaining edges on one side of the inner ring and the outer ring and a single retaining edge on the other side can bear a certain degree of axial load in one direction. Generally, steel plate stamping cage or solid cage made of copper alloy are used. However, some use polyamide shaped cages.
