Axial Spherical Roller B. SKF 29338 E

The SKF 29338 E axial self-aligning roller bearing, measuring 190 × 320 × 78 mm, accommodates high axial forces acting from one side whilst allowing for angular misalignment.

The 29338 E axial self-aligning roller bearing is an open roller bearing from SKF designed specifically to accommodate axial loads acting from one side. It combines a high axial load-carrying capacity with the design feature of compensating for manufacturing-related misalignments and shaft deflection. Manufactured from standard rolling-element bearing steel 100Cr6 in tolerance class P0/PN (ABEC 1), this design belongs to the SKF Explorer performance class. The standardised main dimensions are 190 mm bore, 320 mm outside diameter and 78 mm width.

What loads and deflections does the 29338 E axial self-aligning roller bearing compensate for?

This design is intended for heavy-duty bearing arrangements where dominant axial forces act on rotating shafts. Thanks to the spherical housing raceway, the roller set adjusts with angular freedom and automatically compensates for misalignment and elastic shaft deflection during operation. In addition to the main axial forces, the bearing’s design also allows it to accommodate radially acting load components, provided that a sufficient axial load is applied at the same time.

What are the characteristics of the sheet steel cage and the structural design?

The integrated sheet steel cage guides the rolling elements and is designed for an operating temperature range of –30 to +200 degrees. As a single-direction axial bearing, the component supports loads in a defined axial direction. As axial self-aligning roller bearings are not self-retaining, the shaft ring with roller ring and housing ring can be fitted separately. To ensure slip-free operation, a minimum axial load must be maintained during operation.
