Quality Thrust Ball Bearings

Please wait while we load your selection


Thrust Ball Bearings are separable axial bearings that are produced in both single and double direction acting design.
To assist in simple effective mounting or dismounting the bearing washers, seatings, and cage and ball assemblies, may be individually mounted in their arrangement location.

Thrust ball bearings may accommodate comparatively high axial loads but they must not be exposed to any radial forces.

Due to their specific kinematic behaviour, thrust ball bearings are only suitable for low to medium operating speeds.

Furthermore, they require minimum axial loads for their optimum function.

Since thrust ball bearings do not compensate any misalignment, they are also frequently used in conjunction with sphered housing washers or with both sphered housing washers and seating washers.

Thrust ball bearings are produced in both, single direction and double direction design. The most important design variants are shown on the below.

Single direction thrust ball bearings consist of a shaft washer, a housing washer and a ball and cage thrust assembly, (see a, b and c below).
These bearings are able to accommodate axial loads in one direction only.
Single direction thrust ball bearings of series 511, 512, 513 and 514 have plain housing washers, (see a below)
For applications where some misalignment may occur, single direction thrust ball bearings of the series 532, 533 and 534 are also available with sphered housing washers, figure b.

These bearings may be applied either direct to sphered shaped bearing seats or, they may be used together with seating washers of series U2, U3 or U4 (see c below).

All thrust ball bearing types with flat housing washers do not allow any misalignment.

The contacting surfaces of both shaft and housing seats must be parallel.
Misalignments can only be accommodated by using Thrust Ball bearings with sphered housing washers.
NKE thrust ball bearings are normally fitted with pressed steel cages as standard.

For larger thrust ball bearings solid brass cages, (suffix M), or solid steel cages, (suffix F), are fitted as standard.
NKE thrust ball bearings are produced to normal tolerance class (PN) as standard.
For applications of higher dimensional and geometrical accuracy these bearings are produced to precision tolerance class (e.g. P6) on order request.

Manufactured to:

Standard plans DIN 616
Single direction DIN 711
Thrust ball bearings, double direction
Seating washers DIN 715 DIN 711
