Tapered Roller Bearings SKF 30317

The SKF 30317 tapered roller bearing (85x180x44.5 mm) can accommodate high combined radial and axial loads and features a sheet steel cage.

The SKF 30317 single-row tapered roller bearing is designed for industrial applications in which radial and unilateral axial forces act simultaneously. As a complete rolling bearing, this design comprises the inner ring with a set of rollers and the corresponding outer ring. With a bore of 85 mm, an outside diameter of 180 mm and a width of 44.5 mm, this standard design is suitable for a wide range of bearing arrangements in mechanical engineering and drive technology. The optimised dimensions ensure a stable bearing arrangement under demanding operating conditions.

What loads can the 30317 tapered roller bearing withstand?

In industrial drive technology, the single-row tapered roller bearing 30317 withstands high radial forces as well as axial forces from one direction. As the axial load capacity is design-related and acts on one side only, two bearings are frequently mounted in pairs facing each other in designs. The separate assembly of the inner ring (including the roller cage) and the outer ring facilitates fitting into the housing and onto the shaft. This design ensures that the supported shafts exhibit high rigidity under combined loads.

What distinguishes the Explorer version with a sheet steel cage?

In SKF’s Explorer version, the bearing is designed for optimised friction characteristics and a harmonious contact profile between the tapered rollers and raceways. The integrated sheet steel cage guides the rolling elements evenly and is suitable for an operating temperature range of -30 to +120 degrees. Manufactured to tolerance class P0/PN or ABEC 1, this roller bearing fits precisely into existing assemblies. During commissioning, care must be taken to ensure an appropriate lubrication supply for the application.
