Cylindrical Roller Bearing

-----Single-row Cylindrical Roller Bearing

-----Double-row Cylindrical Roller Bearing

-----Four-row Cylindrical Roller Bearing

The cylindrical roller bearing is dismountable, which is easy to install and dismount. This feature is prominent when the inner ring and outer ring fit on the shaft and housing. The roller and the raceway is modified line contact, get rid of the rid stress. Compared with the ball bearing with the same sime, the cylindrical roller bearing can carry heavy radial load. For the structure, this kind of bearing is suitable for high speed rotation.

Structure type

1. The outer ring without rib N0000, the inner ring without rib NU0000

This kind of bearing can carry heavy radial load, the limit speed is high, can not limit the axial displacement of shaft and housing, can not carry the axial load.

2. The inner ring and outer ring with ribs

NJ0000,NF0000 can limit axial displacement of shaft or housing in one direction, and can carry small axial load in one direction. NU0000+HJ0000,NJ0000+HJ0000,NUP0000 can limit the axial displacement of shaft and housing within the bearing axial clearance and carry small axial load in two direction.

3,Others

RN0000 without outer ring. This kind of bearing is suitable for the parts with radial size limit, the surface of bore diameter is the rolling surface. The hardness, machining accuracy and surface roughness is relevant to the raceway of the ring.

NAL0000 and NNAL0000, the ourter ring with double ribs, this kind of long cylindrical roller bearing is used in petroleum machinery.

Double-row Cylindrical roller bearing, NNU0000, NN0000

Four-row Cylindrical roller bearing, FC, FCD, FCDP. This kind of bearing is also called four-row cylindrical roling mill bearing, which is used in heavy-duty machinery and steel factory.

The material of cage

The cylindrical roller baring adopts copper (steel) cage or pin cage.

Allowable slant angle

For the cylindrical roller bearing, the shaft is not allowed to incline to the hole of housing, but for the single-row cylindrical roller bearing, if the load is small, the axial line of inner and outer ring can incline 2', if the load is heavy, the error can be bigger, but not exceed 4'.
