Axial Deep Groove Ball B. SKF 51110

The SKF 51110 axial deep-groove ball bearing, with dimensions of 50x70x14 mm, accommodates single-direction axial forces within a temperature range of -30 to +150 degrees.

The 51110 axial deep-groove ball bearing guides shafts in the axial direction and supports pure axial forces from a single direction. SKF manufactures this single-acting rolling bearing from standard 100Cr6 bearing steel, which offers high dimensional stability. The design comprises a shaft ring with a 50 mm bore, a housing ring with an outer diameter of 70 mm, and the guided ball and cage assembly with a height of 14 mm. It is primarily used where pure thrust forces in the longitudinal direction act on the bearing arrangement without any radial forces.

What is the 51110 axial deep-groove ball bearing suitable for?

This axial bearing is primarily used in mechanical devices where components must absorb axial compressive loads. Typical applications are found in assemblies with purely axial load transmission. As the design acts on one side only, the bearing specifically supports the shaft in one axial direction. When designing the assembly, care must be taken to ensure that no transverse forces act on the bearing, as the grooved raceways of the discs are designed exclusively for forces in the axial direction.

What is important when fitting the single-acting 51110?

As the 51110 version is not angularly adjustable and is fitted without a spherical washer, the contact surfaces on the shaft and housing must be exactly perpendicular to the axis of rotation. Otherwise, misalignment will lead to uneven load distribution across the balls. The integrated sheet steel cage maintains a uniform distance between the rolling elements and is suitable for operating temperatures ranging from -30 to +150 degrees. Thanks to the standard tolerance class P0 or ABEC 1, the component can be easily integrated into standardised fits.
