Axial Spherical Roller B. SKF 29348 E

The SKF 29348 E axial self-aligning roller bearing accommodates high unilateral axial loads with a 240 mm bore and an outer diameter of 380 mm.

This 29348 E axial self-aligning roller bearing is a heavy-duty roller bearing designed for demanding industrial applications. Its design combines angle-adjustable roller sets with a high load-carrying capacity in the axial direction. Made from standard 100Cr6 rolling bearing steel, the component is suitable for thermal conditions ranging from -30 to +200 degrees. As an SKF Explorer version, the bearing features matched contact surfaces to ensure an even force distribution.

When is the 29348 E axial self-aligning roller bearing used?

The bearing is designed for applications where very high axial forces occur and, at the same time, misalignment or shaft deflection must be compensated for. It is primarily used in bearing arrangements subject to combined loads and high axial loads. As this rolling bearing acts on one side only, it absorbs axial forces specifically in one direction. In addition, the bearing arrangement can transmit limited radial forces, provided that a minimum axial load is applied at the same time.

What are the distinctive features of the sheet steel cage in the axial self-aligning roller bearing?

The sheet steel cage guides the barrel-shaped rollers along the raceways and reduces frictional resistance during rotation. Sheet steel is characterised by low component weight combined with high strength, which benefits the flow of lubricant. In combination with the standard tolerance P0 or ABEC 1, the component can be mounted with dimensional accuracy onto shafts with a diameter of 240 mm and fitted into housings with a 380 mm bore.
