Axial Deep Groove Ball B. SKF 51111

The SKF 51111 single-direction axial deep groove ball bearing accommodates purely axial loads whilst maintaining compact dimensions of 55x78x16 mm.

The 51111 axial deep-groove ball bearing supports shafts in the axial direction and transmits the forces acting upon it in a defined direction. The axial bearing, manufactured by SKF, consists of a shaft ring, a housing ring and the set of balls housed between them. As it is manufactured from standard rolling-element bearing steel (100Cr6), the component offers dimensional stability under load. Standardised mounting dimensions allow for direct replacement in existing assemblies.

In which assemblies does the 51111 axial deep-groove ball bearing absorb axial forces?

This thrust bearing is designed for operating conditions in which purely axial forces from a single direction must be supported. The component must not absorb radial loads. As this version is not angularly adjustable, installation requires precisely perpendicular and rigid contact surfaces on the housing and shaft. Typical applications include rigid bearing arrangements with a unidirectional thrust load, where no misalignment of the axes occurs.

What are the key features of the design with a sheet steel cage and standard tolerances?

The integrated sheet steel cage guides the rolling elements evenly along the raceway whilst being lightweight itself, and allows operating temperatures ranging from -30 to +150 degrees. The component complies with standard tolerance class P0/PN (comparable to ABEC 1) and thus meets the usual industrial requirements for dimensional and concentricity accuracy. The scope of supply comprises the axial bearing only, without washers, so that the housing flange rests flat in the bearing seat.
