The roller body of cylindrical roller bearing is the centripetal roller bearing of cylindrical roller. 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 ring has no edge, NSK cylindrical roller bearings are divided into single row bearings, such as NU, NJ, NUP, N, NF, and double row bearings of 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.
 
The roller and raceway of 1.NSK cylindrical roller bearings are linear contact or repair line contact, radial bearing capacity is large, suitable for heavy load and impact load.
 
2.NSK cylindrical roller bearings have small friction coefficient, suitable for high speed, and the ultimate speed is close to deep groove ball bearings.
 
The 3.NSK cylindrical roller bearing N and NU type can be moved in axial direction, which can be used as a free end support for the change of the relative position of the shaft and the shell caused by the thermal expansion or installation error.
 
4.NSK cylindrical roller bearings have higher requirements for shaft or seat holes, and the relative deflection of outer ring axis after bearing installation should be strictly controlled so as not to cause contact stress concentration.
 
5.NSK cylindrical roller bearing inner ring or outer ring can be separated for easy installation and disassembly.
 
Main uses:
 
Large and medium motor, locomotive and vehicle, machine tool spindle, internal combustion engine, generator, gas turbine, reducer, rolling mill, vibrating screen and lifting transport machinery, etc.
