Axial Deep Groove Ball B. SKF 51315

The SKF 51315 axial deep-groove ball bearing is suitable for shafts with a 75 mm bore and accommodates axial loads on one side.

The 51315 axial deep-groove ball bearing is a standardised rolling bearing designed for purely axial loads. The component has an inside diameter of 75 mm, an outside diameter of 135 mm and a height of 44 mm. Manufactured from standard rolling bearing steel (100Cr6), the sheet steel cage guides the rolling elements in an orderly manner within the raceways. The open design is rated for a temperature range of -30 to +150 degrees.

What operating conditions does the 51315 axial deep-groove ball bearing require?

This rolling bearing is used where axial loads parallel to the shaft axis must be supported in one direction. Typical applications are found in general industrial and mechanical engineering in bearing arrangements subject to unilateral thrust loads. As this bearing acts purely on one side, it supports rotating shafts specifically on one side. Due to its design, this type of bearing cannot accommodate radial forces and requires a separate radial support where necessary.

What is important when fitting the 51315 bearing?

The single-sided axial bearing is not angularly adjustable and does not compensate for misalignment between the shaft and the housing axis. To ensure smooth running, the contact surfaces must be flat and perpendicular to the axis of rotation. The bearing is fitted without additional shims. Thanks to the standardised tolerance class P0/PN (corresponding to ABEC 1), the bearing meets the usual dimensional and running tolerances for shaft fits in mechanical engineering.
