Product Description

NJ238 NJ240 NJ244 NJ248 Large stock original brand Copper Cage Cylindrical Roller Bearing use for machine made in China

       Cylindrical roller bearings  : 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.

Features:

1. The rollers and the raceway are in line contact or trimmed line contact, with large radial bearing capacity, suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
3. N-type and NU-type can move axially, can adapt to changes in the relative position of the shaft and the shell caused by thermal expansion or installation errors, and can be used as free end supports.
4. The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deviation of the axis of the outer ring must be strictly controlled to avoid contact stress concentration.
5. The inner or outer ring can be separated for easy installation and removal
