Axial Deep Groove Ball B. SKF 51126

The SKF 51126 axial deep-groove ball bearing, measuring 130 × 170 × 30 mm, withstands high unilateral axial forces in continuous industrial operation.

This rolling bearing is designed as a single-direction type. It guides shafts in an axial direction and transfers the resulting thrust forces directly to the housing. As it is manufactured from standard rolling-element bearing steel (100Cr6), the component offers high dimensional stability under load. The 51126 axial deep-groove ball bearing is suitable for designs in which purely axial loads are expected to occur and no radial forces act on this bearing.

In which applications is the 51126 axial deep-groove ball bearing used?

It is primarily used where shafts need to be axially fixed. Typical applications include vertical shaft arrangements and bearing arrangements subject to high unilateral thrust forces in mechanical engineering. As the bearing accommodates thrust forces in one direction only, it is often used as a fixed bearing in combination with separate radial bearings. It is important that the load is purely axial, as radial forces would place an uneven load on the rolling element raceways.

What installation requirements does the rigid design entail?

This bearing is not angle-adjustable. The connecting parts on the shaft and housing must therefore be manufactured exactly at right angles to the axis of rotation. Misalignment or tilting leads to edge stresses, which can shorten the service life. The guided sheet steel cage keeps the balls spaced apart and allows for a temperature range of -30 to +150 degrees. During installation, the housing flange must lie flat, as this product is designed without a shim.
