Axial Deep Groove Ball B. SKF 51320

The SKF 51320 axial deep-groove ball bearing is designed to accommodate single-direction axial loads and has dimensions of 100 × 170 × 55 mm.

The 51320 axial deep groove ball bearing is designed as a single-acting rolling bearing for pure axial loads in one direction. With a bore of 100 mm, an outside diameter of 170 mm and a height of 55 mm, the component provides axial support for corresponding shaft axes. SKF manufactures the rings and rolling elements from standard roller bearing steel (100Cr6) to tolerance class P0/PN or ABEC 1. A dimensionally stable sheet steel cage guides the balls evenly between the two raceways.

What is the 51320 axial deep-groove ball bearing suitable for in operation?

This rolling bearing is designed to accommodate high axial forces parallel to the axis of rotation. It is used in industrial bearing arrangements where forces are applied predominantly from one side and where no shaft deflection or misalignment occurs. As this design is intended for purely axial loading, it does not absorb any radial forces. To ensure complete shaft guidance, the bearing arrangement is therefore combined with separate radial bearings.

What installation requirements does the rigid 51320 design have?

This design is not angle-adjustable and is supplied without a shim. Both the shaft shoulder and the housing contact surface must be machined to be flat and perpendicular to the axis of rotation. Misalignment or skewing will result in uneven load distribution across the balls. The specified operating temperature range is between –30 and +150 degrees. As the bearing is of open design, an external lubricant supply and housing-side sealing elements must be provided.
