Cylindrical roller bearing is a bearing in line contact with the raceway.Large load capacity, mainly bearing radial load.The friction between the roller and the ring is small, suitable for high speed rotation.
The inner ring and outer ring of the bearing are separable.
A cylindrical roller bearing with an inner or outer ring without a retaining edge, the inner and outer rings can be moved relative to the axial direction and can be used as free-end bearings.
The cylindrical roller bearing which one side of the inner or outer ring has a double retaining edge, the other side of the ring has a single retaining , can bear a certain degree of axial load in one direction.
Double row cylindrical roller bearing had high rigidity to radial load, mainly used in machine tool spindle.
Generally use steel plate stamping cage, or copper alloy car cage.But some use poly-amide - shaped retainers.
