Axial Spherical Roller B. SKF 29340 E

The SKF 29340 E axial self-aligning roller bearing, measuring 200 × 340 × 85 mm, accommodates high unilateral axial loads and compensates for misalignment.

The 29340 E axial self-aligning roller bearing is a heavy-duty rolling bearing designed for demanding industrial applications. The design combines barrel-shaped rollers with spherical raceways in the housing disc. Thanks to this geometry, the bearing transmits heavy axial forces in one direction whilst simultaneously accommodating both static and dynamic misalignments of the shaft. Manufactured from standard 100Cr6 rolling-element bearing steel in the SKF Explorer design, this component features optimised internal contact surfaces.

What is the 29340 E axial self-aligning roller bearing suitable for in practice?

This type of bearing is primarily used in heavy-duty drivetrains and industrial gearboxes where significant axial thrust forces occur. As the roller arrangement is designed to be angularly adjustable, the bearing compensates for misalignment and deflection of the shaft under load without causing adverse edge loading. Typical applications include vertical shaft lines and heavily loaded large gearboxes, where, in addition to the dominant axial forces, moderate radial loads may also act on the bearing location.

What advantages does the sheet steel cage offer in this axial bearing?

The integrated sheet steel cage guides the rolling elements whilst being lightweight and facilitates unobstructed access of lubricant to the roller end faces. Together with the rolling bearing steel, the bearing unit covers a temperature range from –30 to +200 degrees. Manufacturing is carried out to the standard tolerance P0/PN (corresponding to ABEC 1). When designing the connecting components, it must be taken into account that the bearing is designed for single-sided loading and requires a minimum axial load during operation.
