Axial Deep Groove Ball B. SKF 51317

The 51317 axial deep-groove ball bearing accommodates unidirectional axial forces and, with dimensions of 85x150x49 mm, offers a standardised bearing solution made from rolling bearing steel.

The SKF 51317 axial deep groove ball bearing guides shafts when subjected to purely axial forces in one direction. With a bore of 85 mm, an outer diameter of 150 mm and a height of 49 mm, this rolling bearing is suitable for industrial assemblies where precise axial guidance is required. Manufactured from through-hardened standard rolling-element bearing steel (100Cr6) and guided by a sheet steel cage, the design covers an operating temperature range of -30 to +150 degrees Celsius.

What is the 51317 single-direction axial deep-groove ball bearing suitable for?

This thrust bearing is designed to specifically accommodate high axial loads acting exclusively in one direction. The bearing must not accommodate radial forces. Typical applications include vertically aligned shaft mountings and assemblies subject to predominantly axial loads in mechanical engineering. As the design is not angle-adjustable, the mounting surfaces on the housing and shaft must be parallel to each other and perpendicular to the axis of rotation.

What should be taken into account regarding tolerances and the installation of the 51317 axial deep groove ball bearing?

The bearing complies with the standard tolerance P0/PN (comparable to ABEC 1) and is designed as a single-acting unit without a shim. During design, it must be taken into account that the shaft ring and housing ring have different fit dimensions. The shaft ring fits tightly on the shaft, whilst the housing ring requires clearance within the housing. To ensure stable operation, a sufficient minimum axial load is recommended during operation to prevent the rolling elements from lifting off.
