Axial Deep Groove Ball B. FAG 51115

The FAG 51115 axial deep-groove ball bearing, measuring 75 x 100 x 19 mm, accommodates unilateral axial loads.

The FAG 51115 axial deep-groove ball bearing is designed as a separable rolling bearing for the specific purpose of accommodating single-direction axial forces. The components are made of standard rolling-bearing steel (100Cr6) and are fitted with a sheet steel cage. With a bore of 75 mm, an outside diameter of 100 mm and a height of 19 mm, this design is suitable for assemblies that need to accommodate purely longitudinal forces without any radial load.

What is the 51115 axial deep-groove ball bearing suitable for in mechanical engineering?

This rolling bearing is used for single-sided axial guidance of shafts and spindles in general mechanical engineering. As it is designed to act on one side only, the unit absorbs thrust forces exclusively from one direction. Typical applications include bearing arrangements where axial support is required. Important for the design: The bearing must not be subjected to radial forces, which is why designers divert radial loads via separate bearings.

What is important when fitting the 51115 axial deep groove ball bearing?

As the bearing is subject to the standard tolerance P0/PN (corresponding to ABEC 1) and is not angularly adjustable, installation requires connection surfaces that are precisely at right angles and aligned. Misalignment between the housing and the shaft leads to edge stresses, which accelerate wear. The scope of supply comprises the axial deep-groove ball bearing only, without a washer. For operation, the permissible temperature range of -30 to +150 degrees Celsius must be observed, and the lubrication must be adapted to the thermal load.
