タイトルまたは説明

Cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bear radial load. The friction between the rolling element and the ring rib is small, which is suitable for high-speed rotation. According to whether the ring has flange, it can be divided into single row cylindrical roller bearings such as Nu, NJ, NUP, N, 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 without rib in inner ring or outer ring can move relative to axial direction, so it can be used as free end bearing. The cylindrical roller bearing with double rib on one side of inner ring and outer ring and single rib on the other side can bear axial load in one direction to a certain extent. Generally, steel stamping cages or copper alloy turning solid cages are used. But some use polyamide formed cages.
