Axial Spherical Roller B. SKF 29424 E

The 29424 E axial self-aligning roller bearing (120 × 250 × 78 mm) accommodates heavy axial loads on one side and automatically compensates for angular misalignment during operation.

The SKF 29424 E axial self-aligning roller bearing is a robust rolling bearing designed for heavy axial loads whilst simultaneously accommodating radial forces. With a bore of 120 mm, an outer diameter of 250 mm and a width of 78 mm, this bearing is suitable for demanding industrial drives. The crowned rollers run on a spherical housing raceway, enabling the bearing to compensate for misalignment and shaft deflection. Manufactured from standard rolling-element bearing steel (100Cr6), the Explorer version offers an optimised internal geometry for high loads.

What is the 29424 E axial self-aligning roller bearing suitable for?

This single-acting bearing is used in heavy-duty industrial applications where high axial thrust forces occur. Typical applications include heavy-duty gearbox construction and bearing arrangements with vertical shaft orientation. Thanks to its angularly adjustable design, the 29424 E axial self-aligning roller bearing compensates for misalignment between the shaft and housing. As the rollers are arranged at an angle to the bearing axis, the component transfers not only the primary axial forces but also combined radial loads to the surrounding structure.

What role do the sheet steel cage and tolerance class P0 play in the 29424 E bearing?

During design, operating conditions and installation circumstances determine the suitability of the components. The guided sheet steel cage keeps the rollers stable on their raceway and is suitable for operating temperatures ranging from –30 to +200 degrees. Tolerance class P0 (or ABEC 1) meets the standard accuracy requirements in general mechanical engineering. As the shaft washer and housing washer can be fitted separately, this design facilitates step-by-step installation onto the shaft and into the housing.
