Axial Deep Groove Ball B. FAG 51108

The 51108 axial deep-groove ball bearing from FAG Wälzlager, with dimensions of 40x60x13 mm, accommodates high single-sided axial forces in mechanical engineering.

The 51108 axial deep-groove ball bearing is a separable rolling bearing comprising a shaft ring, a housing ring and the ball and cage assembly housed between them. Its primary function is to absorb and guide axial forces in a defined direction. Manufactured from standard rolling-bearing steel (100Cr6) and fitted with a sheet steel cage, this version covers an operating temperature range from –30 to +150 degrees. Manufactured to tolerance class P0/PN or ABEC 1, these dimensionally accurate components are suitable for industrial bearing applications.

What is the 51108 axial deep-groove ball bearing suitable for?

Design engineers specifically use this bearing in assemblies where purely axial compressive forces occur. As the direction of action is designed to be single-sided, the bearing unit fixes a shaft axially in one direction. The range of applications includes bearing arrangements with unilateral axial loads, where no radial forces act on the axial bearing. The design cannot accommodate radial forces, which is why the component should always be supplemented by separate radial roller bearings in the bearing arrangement.

What are the key considerations for the non-angle-adjustable version?

This roller bearing is not designed to be angularly adjustable and does not include a shim. The mounting surfaces in the housing and on the shaft must be machined to be flat and perpendicular to the axis of rotation. Otherwise, misalignment or tilting between the shaft and the housing will result in uneven load distribution across the rolling elements. Precise alignment of the mating parts ensures that the washers make full contact and that smooth running is maintained.
