Cylindrical Roller Bearing

Cylindrical rollers and raceways are line contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ferrule is small, which is suitable for high-speed rotation. According to whether the ring has ribs, 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 has a detachable inner ring and outer ring.

Cylindrical roller bearings without ribs in the inner ring or outer ring, the inner ring and outer ring can move relative to the axial direction, so it can be used as a free end bearing. A cylindrical roller bearing with double ribs on one side of the inner ring and outer ring, and a single rib on the other side of the ring, which can withstand a certain degree of axial load in one direction. Steel stamping cages are generally used, or copper alloy car-made solid cages. But there are also some polyamide shaped cages.
