Cylindrical roller bearings
Cylindrical Roller Bearings, the rolling element is a radial rolling bearing with cylindrical rollers. 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.
