Spherical Roller Bearings SKF 22320 E

The SKF 22320 E self-aligning roller bearing, with dimensions of 100 × 215 × 73 mm, withstands heavy radial loads and compensates for shaft misalignment.

The SKF 22320 E self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. It has a cylindrical bore of 100 mm, an outer diameter of 215 mm and a width of 73 mm. The design is characterised by the hollow-spherical outer ring raceway. This allows the bearing to self-align in the event of shaft deflection. Manufactured from standard 100Cr6 rolling bearing steel in the SKF Explorer design, the open construction withstands operating temperatures from -30 to +200 °C.

What is the 22320 E spherical roller bearing suitable for in industrial applications?

This self-aligning roller bearing is particularly suitable for heavy-duty machinery designs subject to high radial forces and shock loads. Typical applications include mounting positions with shaft deflection and misalignment. As the outer ring compensates for angular misalignment, the bearing operates without disruptive edge pressure. The integrated sheet steel cage guides the symmetrical rollers stably through the raceways, enabling the bearing to withstand demanding operating conditions.

What are the advantages of P5 running accuracy and the integrated lubrication groove?

When selecting the 22320 E self-aligning roller bearing, dimensional and running characteristics play a key role. The bearing combines standard dimensional accuracy (PN) with increased running accuracy of tolerance class P5. This results in improved shaft concentricity and reduces vibrations during operation. The lubrication groove with holes in the outer ring facilitates relubrication whilst the bearing is installed. As this is an open bearing, you can select the lubricant and external seal to suit your design.
