Axial Deep Groove Ball B. FAG 51228

The FAG 51228 axial deep-groove ball bearing, with dimensions of 140 × 200 × 46 mm, supports pure axial loads from a single direction.

The 51228 axial deep-groove ball bearing is designed for the precise guidance of shafts under unilateral axial loading. The design, comprising a shaft ring, a housing ring and a ball-guided sheet steel cage, can be dismantled, which simplifies the installation of the components. Manufactured from standard rolling bearing steel 100Cr6 in tolerance class P0/PN or ABEC 1, this version is suitable for operating temperatures ranging from -30 to +150 degrees.

What functions does the 51228 axial deep-groove ball bearing fulfil in the design?

This bearing is primarily used in general mechanical engineering where pure compressive forces parallel to the axis of rotation need to be absorbed. Typical applications include vertical shaft mountings and bearing arrangements with a single-sided guiding force. As the design is single-acting, the bearing specifically absorbs axial forces from one direction. This bearing type is not intended for radial loads and must be supplemented with radial bearings when subjected to combined loads.

What should be taken into account when fitting the 51228 axial deep-groove ball bearing?

As this model is not angularly adjustable, the design requires contact surfaces that are flat and aligned at right angles to the shaft axis. Misalignments cannot be compensated for without shims and may lead to uneven edge loads. In addition, care must be taken to ensure the rings are correctly positioned: the shaft ring with a 140 mm bore is mounted on the shaft, whilst the housing ring with an outer diameter of 200 mm rests against the housing.
