Cylindrical roller bearings NJ Series

The internal structure of cylindrical roller bearing adopts rollers arranged in parallel, and spacers or spacers are installed between the rollers, which can prevent the inclination of the rollers or the friction between the rollers, and effectively prevent the increase of the rotational torque. Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs or not, 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 structure in which the inner ring and the outer ring can be separated.

Почта

NJ series bearings have ribs on both sides of the outer ring, and ribs on one side of the inner ring. Can withstand a certain amount of unidirectional axial load.
