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.
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.
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.
The bearing has a 50 mm bore on the shaft flange, an outer diameter of 70 mm on the housing flange and a total width of 14 mm. These standardised dimensions enable a precise fit when installed on corresponding shaft shoulders and in housing bores in mechanical engineering applications.
The bearing accommodates only axial loads acting on the shaft from a single direction. By design, this type of bearing is not suitable for radial forces. If combined loads occur, a separate radial bearing must be fitted alongside the axial bearing to accommodate the radial forces.
No, the bearing is not angle-adjustable and has flat discs without spherical washers. It is therefore sensitive to misalignment between the shaft and the housing. All contact surfaces must be precisely at right angles and flat in order to prevent edge stresses and premature wear of the rolling elements.
The bearing, made from 100Cr6 roller bearing steel with a sheet steel cage, operates within a temperature range of -30 to +150 degrees. During commissioning, a lubricant must be selected that meets these thermal requirements, as the open design has no integrated seals.
Tolerance class P0, also known as standard tolerance or ABEC 1, defines the permissible dimensional and running deviations of the discs. It represents the established industry standard for general mechanical engineering and ensures a precise fit on standard shafts and in housing fits.
The sheet steel cage guides the rolling elements safely along their circular path and prevents the balls from coming into contact with one another. It is characterised by its low weight and good lubricant permeability, and withstands both mechanical and thermal stresses within the permissible temperature range.
