Axial Spherical Roller B. SKF 29330 E

The SKF 29330 E axial self-aligning roller bearing, measuring 150 × 250 × 60 mm, accommodates high unilateral axial forces and compensates for misalignment.

The 29330 E axial self-aligning roller bearing belongs to the group of self-aligning roller bearings designed primarily for axial loads. Thanks to the barrel-shaped rolling elements on a spherical housing raceway, this design compensates for both static and dynamic misalignments of the shaft. At the same time, the bearing accommodates radial load components in addition to axial forces. Manufactured from 100Cr6 bearing steel in the SKF Explorer design, this version is designed for demanding industrial drives in continuous operation.

In which applications does the 29330 E axial-spherical roller bearing prove its worth?

Design engineers primarily select the 29330 E axial self-aligning roller bearing for heavy-duty shaft supports where high axial forces and elastic shaft deflection occur simultaneously. Typical applications include large industrial drives and vertical shaft lines subject to high unilateral thrust loads. The spherical housing raceway prevents edge stresses on the rollers when the shaft deflects slightly under load. Furthermore, the rolling bearing withstands shock loads without impairing the guidance of the shaft collar.

What are the key features of the cage and material in the 29330 E?

The integrated sheet steel cage guides the rolling elements with low friction and keeps the weight of the rotating components to a minimum. The component is resistant to common lubricating oils and greases. Together with the rolling bearing steel, the bearing assembly covers a thermal operating range from -30 to +200 degrees. As this is a single-direction bearing of tolerance class P0/PN or ABEC 1, operation requires a constant minimum axial load to ensure the rollers run without slippage.
