  Cylindrical Roller Bearings

The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling element and the ring rib is small, and it is suitable for high-speed rotation. According to whether the ring has rib or not, it can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is a separable structure of inner ring and outer ring. Cylindrical roller bearing without rib on inner or outer ring, whose inner ring and outer ring can move relative to each other in axial direction, can be used as free end bearing. Cylindrical roller bearing with double ribs on one side of the inner ring and outer ring and single rib on the other side of the ring can withstand axial load in one direction to a certain extent. Generally, pressed steel cages or solid copper alloy cages are used. However, some of them use polyamide shaped cages.
