Axial Deep Groove Ball B. SKF 51113

The SKF 51113 axial deep-groove ball bearing reliably withstands unilateral axial forces with a 65 mm bore, 90 mm outer diameter and 18 mm height.

This 511 series rolling bearing is designed for the axial guidance of shafts under unidirectional loading. Manufactured from standard roller bearing steel (100Cr6), the design comprises a shaft ring with a bore diameter of 65 mm, a housing ring with an outer diameter of 90 mm, and a seat for the balls and cage. The component is used as standard without a washer. The integrated sheet steel cage guides the rolling elements evenly along the raceways. The unsealed design is rated for operating temperatures from –30 to +150 degrees.

What loads and operating conditions determine the 51113 axial deep-groove ball bearing?

It is used in applications where axial forces parallel to the axis of rotation must be absorbed and radial loads are supported by separate radial bearings. Due to its single-direction action, the bearing specifically supports the shaft in one thrust direction. The bearing is suitable for shaft guides and mechanical drives where axial compressive forces predominate. Due to its design, this rolling bearing must not be used to support purely radial forces, as the raceways are designed exclusively for axial loads.

What should be taken into account when mounting and aligning bearing 51113?

As this model is not angle-adjustable, the bearing mounting requires careful right-angled alignment of the contact surfaces on the housing and shaft. Misalignment or skew cannot be compensated for without a spherical shim and will result in uneven loading. Manufacture to tolerance class P0 (PN or ABEC 1) defines precise fit conditions within the standard industrial range. The open axial bearing requires professional initial lubrication with a lubricant suitable for the operating conditions prior to first commissioning.
