Cylindrical roller thrust bearings consist of cylindrical rollers and cage thrust assemblies and two bearing washers. The design can be single-row or double-row. They are rigid, have high load capacity and are resistant to impact loads. They can only accommodate axial forces.
Boundary dimensions

The boundary dimensions of cylindrical roller thrust bearings given in the dimension tables comply with the ISO 104 international dimension plan.

Designs

The components of cylindrical roller thrust bearings allow a combination of a cage with rollers and raceways formed by individual machine parts, or a combination of one raceway formed by a machine part and a bearing ring. A separate cage with rollers has the additional designation K, a separate shaft washer is designated WS and a separate housing ring is designated GS.

Designation

The designation of bearings with the basic design is given in the dimension tables. The difference from the basic design is designated by additional marks.

Cages
Cylindrical roller thrust bearings cages are made of polyamide 66 (designation TN) or brass (designation M).
Precision

Cylindrical roller thrust bearings are normally manufactured with normal precision grade P0 (the P0 mark is not designated). Bearings with higher precision grades P6 and P5 are available for special arrangements that require higher precision. Limiting values for dimensional and running accuracy deviations are given in ISO 199.

Minimum Axial Load

Cylindrical roller thrust bearings must be subjected to a certain minimum load to ensure reliable bearing function. If this load is not observed, abnormal rolling and slipping of the rolling elements and consequent damage to the raceways may occur.

The minimum load is calculated as follows:

Where
Fa min – minimum axial load [kN]
C0a – static load capacity [kN]
n – speed [min-1]
M – coefficient of minimum axial load
(The values are given in the dimension tables.)

Unless the minimum load is caused naturally in the bearing arrangement, the bearing must be loaded with additional force by a shaft nut or springs.
