Cylindrical roller bearing
The cylindrical roller and the raceway are line contact bearings. The load capacity is large, and it is mainly subjected to radial load. The friction between the rolling body and the ring edge is small, which is suitable for high-speed rotation. According to whether the rings have edges, they can be divided into single row bearings, such as NU, NJ, NUP, N, NF, and double row bearings such as NNU and NN. The bearing is a detachable structure in the inner ring and outer ring. The inner ring and outer ring of the cylindrical roller bearing without inner ring or outer ring can move relative to the axial direction, so it can be used as a free end bearing. One side of the inner ring and outer ring has two sides, and the other side has a cylindrical roller bearing with a single side, which can bear a certain degree of axial load in one direction. Generally use steel stamping cage or copper alloy car cage. But some use polyamide forming cage.

Cylindrical roller bearing features:
1. roller and raceway for line contact or repair line contact, radial bearing capacity is large, suitable for bearing heavy load and impact load.
2. the friction coefficient is small, suitable for high speed, and the limit speed is close to deep groove ball bearings.
3. the N and NU can be moved axially, which can be adapted to the relative position changes between the shaft and the shell caused by thermal expansion or installation error, and can be used for free end support.
4. the processing requirements for the shaft or seat hole are higher, and the relative deflection of the outer ring axis after bearing installation should be strictly controlled so as not to cause contact stress concentration.
5. inner ring or outer ring can be separated for easy installation and disassembly.
