Tapered Roller Bearings FAG 30317

The FAG 30317 tapered roller bearing, with its main dimensions of 85 × 180 × 44.5 mm, is designed to withstand high radial loads as well as unilateral axial loads in mechanical engineering applications.

This single-row tapered roller bearing 30317 is designed as a complete rolling bearing and consists of an inner ring with a roller cage and the corresponding outer ring. Thanks to the tapered arrangement of the rolling elements, the design effectively transfers combined forces to the surrounding structure. The component is used where compact dimensions combined with high load-carrying capacity are required. The integrated sheet steel cage guides the rolling elements and is suitable for operating temperatures ranging from -30 to +120 degrees.

What is the 30317 tapered roller bearing suitable for?

This 30317 tapered roller bearing is designed for applications where strong radial forces and single-sided axial forces occur simultaneously. As a single tapered roller bearing can only accommodate axial loads in one direction, in practice they are usually fitted in pairs, facing each other. Such arrangements provide precise guidance of the shaft as well as high rigidity of the entire bearing assembly under load.

What are the key considerations regarding tolerance and installation of the 30317 tapered roller bearing?

The bearing is manufactured to tolerance class P0/PN, which corresponds to ABEC 1 and represents the standard tolerance for industrial applications. As the inner ring with roller cage and the outer ring can be fitted separately, installation in the housing and on the shaft with a bore diameter of 85 mm can be carried out independently. To ensure even contact across all rollers, the precise adjustment of the axial bearing clearance during assembly is crucial.
