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.
There are single row bearings such as Nu, NJ, NUP, N and NF and NNU and NN double row bearings according to whether the ferrule has a retaining edge or not.
The bearing has 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 or outer ring and a single retaining edge on the ferrule on the other side can bear a certain degree of axial load in one direction.
Double row cylindrical roller bearing, with high rigidity to radial load, is mainly used for machine tool spindle.
Generally, steel plate stamping cage or copper alloy car cage are used. However, some use polyamide shaped cages.
