Cylindrical Roller Thrust Bearings

Cylindrical roller thrust bearings are suitable for heavy axial load accommodation. They are relatively insensitive to shock loads. They are very stiff and require little axial space. They are most commonly available as single direction bearings and can accommodate axial loads acting in single direction. Cylindrical thrust bearings may be produced in single row and double row designs. Double row patterns are mainly used where thrust ball bearings have insufficient load carrying capacity.

The cylindrical surface of the rollers is slightly relieved towards the ends. Thus the contact profile virtually eliminates damaging edge stresses. The bearings are of separable type, the individual components can be mounted separately.

Double direction cylindrical roller thrust bearings can easily be assembled by combining appropriate shaft washers or housing with two cylindrical roller and cage thrust assemblies and a suitable intermediate washer with internal or external centering.These intermediate washers should have the same quality and hardness as the bearing washers.

Dimensions - The boundary dimensions of cylindrical roller thrust bearings correspond to ISO.

Tolerance - Cylindrical roller thrust bearings are produced to Normal tolerances as standard.

Misalignment - They cannot tolerate any misalignment of the shaft with respect to the housing or any angular misalignment.

Cages - They are produced in injection molded cage of glass fiber or reinforced polyamide machined brass cage. For high temperature applications, metal cages should be preferred.

Minimum Load - The requisite minimum axial load to be applied to cylindrical roller thrust bearings can be obtained from formula


This needs to be adhered to if the bearings have to operate at high speeds or are subjected to rapid changes in the direction of load.
