Axial Deep Groove Ball B. SKF 51210

The SKF 51210 axial deep groove ball bearing, measuring 50x78x22 mm, accommodates unidirectional axial forces in mechanical and plant engineering.

The SKF 51210 axial deep groove ball bearing is designed to guide shafts subjected to unidirectional axial loads. Manufactured from standard rolling-bearing steel (100Cr6), this assembly consists of a shaft ring, a housing ring and, between them, a ball ring with a sheet steel cage. With a bore of 50 mm, an outside diameter of 78 mm and a height of 22 mm, this rolling bearing supports axial forces in a defined direction. The bearing is designed for operating temperatures ranging from -30 to +150 degrees.

What is the 51210 single-direction axial deep groove ball bearing suitable for?

Design engineers and maintenance technicians primarily use the 51210 axial deep-groove ball bearing where purely axial loads occur in one direction and radial forces are absorbed by separate radial bearings. As it is manufactured to tolerance class P0/PN (ABEC 1), this component is suitable for applications in general mechanical engineering involving axially loaded bearings. As this thrust bearing transmits axial forces exclusively, no radial load must be applied. The design supports the shaft axially on one side.

What do you need to bear in mind regarding angular adjustability during assembly?

When designing the bearing mounting, please note that the 51210 axial deep-groove ball bearing is not angularly adjustable. The contact surfaces on the shaft and housing must be exactly at right angles to and parallel with the axis to avoid damaging edge loads. As this product is designed without additional shims, misalignments cannot be automatically compensated for. The sheet steel cage guides the rolling elements across the entire temperature range from -30 to +150 degrees and requires appropriate lubrication.
