Axial Spherical Roller B. SKF 29426 E

The SKF 29426 E axial self-aligning roller bearing accommodates high unilateral axial forces with a 130 mm bore, 270 mm outer diameter and 85 mm width.

The SKF 29426 E axial self-aligning roller bearing is designed for demanding industrial applications where heavy axial loads act parallel to the shaft. Manufactured from standard roller bearing steel (100Cr6) in the Explorer design, this bearing is characterised by high load-carrying capacity and dimensional stability. The angularly adjustable design automatically compensates for misalignment and shaft deflection during operation. This ensures that the pressure is distributed evenly across the crowned rollers, thereby reducing friction and minimising wear.

What loads can the 29426 E axial self-aligning roller bearing accommodate?

This bearing design accommodates high axial thrust forces whilst also being capable of transmitting accompanying radial forces. Typical applications include heavy-duty mechanical engineering and industrial gearboxes subject to high loads. As the design compensates for angular misalignment between the shaft and housing, operation remains stable even when shaft deflection occurs. The component acts on one side only and transmits axial forces in a specified direction.

What conditions apply to the operation of the single-acting design?

The defined load direction is crucial during design, as single-acting axial bearings only accommodate forces in one axial direction. A minimum axial load during operation ensures that the roller set rolls smoothly on the raceways without slippage. The sheet steel cage guides the rolling elements in an orderly manner and is suitable for operating temperatures ranging from -30 to +200 degrees. With tolerance class P0/PN (ABEC 1), this design complies with the standard fits for cylindrical bearing seats.
