1. Cylindrical Roller Bearings
Cylindrical roller bearings are radial rolling bearings in which the rolling elements are cylindrical rollers. Cylindrical rollers and raceways are line contact bearings. Load capacity, mainly bear radial load. The rolling element has little friction with the ferrule rib and is suitable for high speed rotation. According to the ferrule with or without 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 is a structure in which the inner ring and the outer ring are separable. Models are divided into 200 series, 300 series, 400 series, 1000 series, 2200 series, 2300 series.
