Axial Spherical Roller B. SKF 29420 E

The SKF 29420 E axial self-aligning roller bearing accommodates high axial loads on one side, with a 100 mm bore, 210 mm outer diameter and 67 mm width.

This 29420 E axial self-aligning roller bearing is designed as a single-acting rolling bearing for demanding industrial applications. The version made from standard bearing steel 100Cr6 features raceways arranged at an angle to the bearing axis, enabling the bearing to accommodate radial load components in addition to dominant axial forces. Thanks to the crowned rollers, the component automatically compensates for misalignment or shaft deflection during operation. SKF’s Explorer design offers an optimised internal geometry for even load distribution.

In which designs is the 29420 E axial self-aligning roller bearing used?

The bearing is primarily used in mounting arrangements subject to high unilateral axial forces and simultaneous radial loads. As the design compensates for angular misalignment, it is suitable for applications where the housing may deform during operation or where the shaft may deflect elastically under load. The sheet steel cage guides the rolling elements and supports operation across a wide temperature range from –30 to +200 degrees Celsius.

What function does the sheet steel cage perform during operation?

The integrated sheet steel cage combines low weight with mechanical stability. It keeps the barrel-shaped rollers at a distance from one another and allows unobstructed access of lubricant to the contact surfaces. Manufactured to tolerance class P0/PN (corresponding to ABEC 1), the bearing meets standardised precision specifications for mechanical engineering. To ensure slip-free operation, the single-acting bearing always requires a minimum axial load due to operational conditions.
