Axial Deep Groove Ball B. SKF 51115

The SKF 51115 axial deep groove ball bearing accommodates unilateral axial forces and is specifically designed to support shaft components measuring 75x100x19 mm.

The SKF 51115 axial deep groove ball bearing is designed for pure axial loads in one direction. With an inside diameter of 75 mm, an outside diameter of 100 mm and a height of 19 mm, this design supports rotating shaft components against axial thrust forces. Manufactured from standard rolling bearing steel (100Cr6) with a robust sheet steel cage, the bearing is suitable for industrial assemblies with coplanar contact surfaces. It is manufactured to tolerance class P0/PN or ABEC 1.

What is the 51115 single-direction axial deep groove ball bearing suitable for?

This single-direction thrust bearing supports shafts subjected to axial forces acting constantly from a single direction. This design is suitable for shaft mountings where purely axial thrust forces need to be absorbed. As the bearing is not angularly adjustable, the design requires mounting surfaces machined at right angles to the axis of rotation. This design cannot accommodate radial forces, which is why the shaft must be guided radially by a separate component.

What is important to bear in mind when installing without a separate shim?

Model 51115 is fitted without a separate shim, which makes it essential that the housing surfaces are flat and dimensionally stable. Misalignment between the shaft axis and the housing bore will quickly lead to uneven load distribution across the rolling elements. When fitting, ensure that the shaft washer and housing washer are kept clearly separate, as their internal diameters differ slightly. The combination of a sheet steel cage and roller bearing steel also allows for operating temperatures ranging from -30 to +150 degrees.
