Axial Deep Groove Ball B. FAG 51105

The FAG 51105 single-direction axial deep-groove ball bearing absorbs purely axial forces and fits onto shafts with a diameter of 25 mm.

The FAG 51105 axial deep groove ball bearing supports axial forces in one direction and guides shafts axially. With key dimensions of a 25 mm bore, 42 mm outside diameter and 11 mm width, this design is suitable for compact installations. Manufactured from standard 100Cr6 rolling-bearing steel and fitted with a guided sheet steel cage, this rolling bearing is designed for operating temperatures ranging from -30 to +150 degrees. Manufactured to tolerance class P0/ABEC 1, it ensures smooth concentricity in industrial assemblies.

What is the 51105 axial deep-groove ball bearing suitable for?

This axial bearing is specifically designed to accommodate predominantly axial loads acting on the shaft from a single direction. As axial deep groove ball bearings must not bear any significant radial forces, designers usually combine them in practice with separate radial bearings. This design is used in bearing arrangements with a purely axial load direction, where guided rotational movements take place under axial pressure. A prerequisite for trouble-free operation is a precisely perpendicular abutment surface on the housing and shaft.

What distinguishes the single-acting design without a shim?

Model 51105 belongs to the category of non-angle-adjustable axial bearings and is designed without a separate shim. As a result, the unit is sensitive to misalignment between the shaft and the housing bore; the mating parts must be manufactured to be plane-parallel. During installation, the arrangement of the washers differs: the shaft washer with the smaller bore sits tightly on the shaft, whilst the housing washer has some play within the housing. The sheet steel cage keeps the rolling elements at a distance and is designed for operating temperatures up to +150 degrees.
