Cylindrical roller bearings

Cylindrical rollers have linear contact with the raceway,and the bearings can carry heavier load. Applications are found in situations characterized by heavy load and shock load and also high rotation speed.

The N type and NU type bearings can be movable along the shaft. They can adapt the position changes between the shaft and housing caused by the thermal expansion or the mounting erro and are most suitable for free end shafts.

NJ and NF types can accept certain axial load in one direction, and NUP type can accept certain axial load in two directions.

Inner ring and outer ring can be separable, and they are conbenient to mount and dismount.

The rigidity in carrying radial load in the NNU and NN types make them applicable for machine tool spindles.

FC, DCD and FCDP type can carry comparatively heave radial load and are mainly applied for mill rolls.

Applications of these bearings are mostly found in middle-sized and large-sized motors, electricity generators, internal comubustion engines,machine tool spindles, decelerarion devices, unloading and lifting machines and other industral machines.

Single-row cylindrical roller bearings

NU type and N type cylindrical roller bearings allow the shaft to move in the axial direction within certain limits in relation to the housing. Therefore, they can be used as bearings on the r\free end of the shaft.

NJ type cylindrical roller bearing can carry the axial load within certain limies in double directions.
