Thrust ball bearings are available in single and double acting versions. They sustain axial loads only, and therefore should not be used where radial loads are present.

The thrust loading should not drop below a minimum axial load, maintaining contact between the balls and the track when centrifugal forces are present.

They are manufactured in the following series: 511, 512, 513, 514, 522, 523

and 524.

Dimensions in accordance with ISO 104-2002 Single-acting thrust ball bearings

Single acting thrust ball bearings are used to carry thrust loads in only one direction and cannot carry radial loads. They are made up of a shaft washer, a ﬂat housing washer and a ball and cage assembly. These bearings can be easily mounted by separately ﬁtting each washer.

Double-acting thrust ball bearing,These bearings can carry thrust loadings in both directions. They are ﬁtted with an extra thrust washer and two ball and cage assemblies.

Minimum load

The thrust ball bearing requires a minimum axial load, so that the rolling elements maintain rolling contact and sliding is minimized. “Fam” can be obtained from formula:

Fam = M [ ]

-n Max 1000

[N]

where:

Fam = minimum thrust load (N) M = Factor for minimum load n = speed in RPM
