Axial Deep Groove Ball B. SKF 51216

The SKF 51216 axial deep-groove ball bearing accommodates single-direction axial loads with a shaft diameter of 80 mm in industrial applications.

The 51216 axial deep groove ball bearing is a separable rolling bearing specifically designed to accommodate pure axial forces in one direction. With dimensions of 80 mm bore diameter, 115 mm outside diameter and 28 mm height, the bearing provides axial support for rotating shafts. Manufactured from standard roller bearing steel (100Cr6) and fitted with a sturdy sheet steel cage, the unit is designed for operating temperatures ranging from -30 to +150 degrees. Thanks to its separable design, the housing washer, shaft washer and ball set can be handled separately during installation.

In which applications is the 51216 axial deep groove ball bearing used?

The design is suitable for assemblies in general mechanical engineering where medium to high axial loads must be supported parallel to the axis of rotation. The rolling bearing absorbs thrust forces in one direction, but by its very nature is not intended for transverse or radial loads. If combined forces occur in a bearing arrangement, additional radial bearings must be incorporated to ensure that no transverse forces act on the raceways of the rings.

What environmental requirements does the non-angle-adjustable design impose?

As this model is not angularly adjustable, the flat geometry of the raceways requires precisely right-angled machined contact surfaces on the shaft and housing. The bearing cannot compensate for angular or misalignment errors, as uneven edge loads would impair its running performance. SKF manufactures this product to tolerance class P0/PN or ABEC 1. The product comprises the axial deep-groove ball bearing only, without shims, consisting of a shaft disc, a housing disc and the guided ball and cage assembly.
