Axial Deep Groove Ball B. SKF 52311

The SKF 52311 double-acting axial deep groove ball bearing supports shafts with a 45 mm bore on both sides, with an outer diameter of 105 mm and a height of 64 mm.

The SKF 52311 axial deep groove ball bearing is a double-acting rolling bearing designed to accommodate high axial forces from both directions. Comprising a shaft ring, two housing rings and two separate sets of rolling elements, this design supports the shaft in both thrust directions. Manufactured from standard roller bearing steel (100Cr6) with a robust sheet steel cage, the thrust bearing covers an operating temperature range from -30 to +150 degrees. Its use is recommended wherever only axial loads, without any radial forces, act on the bearing.

What is the 52311 double-acting axial deep groove ball bearing suitable for?

The 52311 axial deep-groove ball bearing is used in bearing arrangements where alternating thrust forces occur in both axial directions. As the design transmits purely axial forces, a separate radial bearing provides the radial shaft support during operation. Due to its design, the bearing does not tolerate misalignment and requires flat, precisely right-angled machined mounting shoulders in the housing.

What is important when installing without a shim?

This model is supplied as a bearing unit only, without spherical washers, and is not angle-adjustable. Misalignment between the shaft and the housing bore quickly leads to edge running and uneven load distribution across the ball sets. The connecting surfaces must therefore be of high dimensional and positional accuracy. Manufactured to standard tolerances (P0/PN or ABEC 1), the rolling bearing can be fitted with dimensional accuracy. As an open component, it requires an external lubricant supply as well as a suitable seal in the surrounding housing.
