Spherical Roller Bearings SKF 22224 EK/C3

The SKF 22224 EK/C3 self-aligning roller bearing, with a 120 mm tapered bore and C3 clearance, offers high load-carrying capacity in the face of shaft deflection and misalignment.

The SKF 22224 EK/C3 self-aligning roller bearing is designed for demanding bearing applications involving high radial and axial loads. The design automatically compensates for angular misalignment between the inner and outer rings during operation. The open bearing, made from standard roller bearing steel 100Cr6, has main dimensions of 120x215x58 mm. It withstands operating temperatures from -30 to +200 degrees Celsius and is suitable for continuous industrial loads in heavy machinery.

What loads can the 22224 EK/C3 self-aligning roller bearing accommodate?

This roller bearing is particularly suitable for demanding applications involving combined forces. It accommodates high radial main loads whilst simultaneously withstanding axial forces in both directions. As the outer ring features a continuous hollow-spherical raceway, misalignment and elastic shaft deflection do not result in harmful edge stresses. The integrated sheet steel cage guides the symmetrical rollers precisely and keeps friction within the bearing to a minimum.

What are the advantages of a tapered bore and C3 clearance?

The EK design features a tapered bore with a taper ratio of 1:12. This allows the bearing to be mounted either directly onto a tapered shaft seat or onto cylindrical shafts using a mounting or withdrawal sleeve. The slightly increased radial clearance (C3) compensates for the radial expansion of the inner ring when the fit is tightened. An integrated lubrication groove with lubrication holes in the outer ring also facilitates targeted relubrication within the housing.
