Axial Deep Groove Ball B. SKF 51207

The SKF 51207 axial deep groove ball bearing accommodates unilateral axial loads and guides shafts with a 35 mm bore and an outer diameter of 62 mm.

The 51207 axial deep-groove ball bearing is designed to support rotating machine components subjected to pure axial forces from a single direction. This SKF rolling bearing is made from standard bearing steel (100Cr6) and has a 35 mm bore, an outer diameter of 62 mm and a height of 18 mm. By design, this type of bearing cannot accommodate radial forces. A guided sheet steel cage keeps the rolling elements on the specified raceway and ensures smooth running under load.

What is the 51207 single-direction axial deep groove ball bearing suitable for?

This rolling bearing is used in applications where designs require defined axial forces in one direction. Typical applications include vertical or horizontal mounting points in general mechanical engineering subject to unilateral thrust loads. As this is a single-direction design, the bearing provides axial support to the shaft on one side. Such bearings are not designed for alternating load directions. Additional radial support via separate radial bearings is required in these systems.

What is important to bear in mind regarding the installation and tolerance class P0 for bearing 51207?

The bearing is manufactured to the standard tolerance class P0 (equivalent to ABEC 1), which complies with the standards for regular industrial applications. As this version is not angle-adjustable and is supplied without a spherical washer, the housing and shaft contact surfaces must be perpendicular to the axis of rotation. Otherwise, misalignment will lead to localised edge loads on the raceways. The permissible temperature range of -30 to +150 degrees allows for use in demanding thermal environments, provided the correct lubricant is used.
