Axial Deep Groove Ball B. FAG 51112

The FAG 51112 axial deep-groove ball bearing, with dimensions of 60 × 85 × 17 mm, supports single-sided axial loads in mechanical engineering and fixture construction.

The 51112 axial deep-groove ball bearing absorbs pure axial forces from one direction and guides the shaft axially to one side. Manufactured from standard rolling-bearing steel (100Cr6), the component withstands high compressive stresses on the rolling elements. FAG equips this design with a sheet steel cage that keeps the balls spaced apart. The bearing operates within a temperature range of –30 to +150 degrees and complies with the standard tolerance class P0/PN (ABEC 1).

What loads can the 51112 axial deep-groove ball bearing accommodate?

This rolling bearing is primarily designed to accommodate axial forces in stationary or guided axles and shafts. As it is a single-direction axial bearing, it supports only axial thrust forces from a defined direction. The component must not be used to support radial loads; combined loads therefore always require a separate radial bearing for lateral support. Typical applications include bearings in mechanical engineering subject to purely single-sided axial loads.

What is important to bear in mind when installing the single-acting bearing?

Design engineers must bear in mind that this series is not angularly adjustable. The mating surfaces on the shaft and housing must be flat and machined at right angles to the axis of rotation, as misalignment leads to localised edge stresses on the raceways. The scope of supply includes the axial deep-groove ball bearing without a washer. During assembly, care must be taken to distinguish between the shaft washer and the housing washer: the shaft washer has a 60 mm bore with a tight fit, whilst the housing washer is larger to allow the shaft to pass through without contact.
