Cylindrical Roller Bearing Specification
Cylindrical Roller Bearing Description
Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the retaining edge of the ring 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 separable structure with inner ring and outer ring.
Cylindrical roller bearings with no ribs on the inner 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. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can bear a certain degree of axial load in one direction. Generally use steel stamping cages or copper alloy car solid cages. But there is also a part of the use of polyamide forming cage.
