Spherical Roller Bearings SKF 22322 EK

The SKF 22322-ek spherical roller bearing, with a 1:12 tapered bore, an outer diameter of 240 mm and a width of 80 mm, offers high load-carrying capacity under misalignment conditions.

The 22322-ek self-aligning roller bearing is a double-row rolling bearing designed for demanding mechanical loads. This SKF component accommodates heavy radial loads as well as simultaneously acting axial forces in both directions. Thanks to the spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation. Manufactured from standard rolling-bearing steel, the bearing housing retains its dimensional stability under continuous loading.

What loads does the 22322-ek self-aligning roller bearing accommodate?

This roller bearing is used in designs where high radial forces occur in combination with additional axial forces and where elastic deformations of the shaft must be taken into account. The symmetrical arrangement of the two rows of rollers ensures that the load is distributed evenly across the rolling elements. As this is an open bearing without an integrated seal, the lubricant reaches the contact surfaces between the rollers and raceways unhindered. The permissible temperature range extends from –30 to +200 °C, covering a wide thermal operating range.

What are the distinctive features of the tapered bore and the sheet steel cage?

The suffix refers to the tapered bore with a taper ratio of 1:12. The bearing can be mounted directly onto a suitably tapered shaft seat or, using a mounting or withdrawal sleeve, onto a cylindrical shaft. The integrated sheet steel cage separates and guides the rolling elements precisely whilst having a low mass. The design with standard radial bearing clearance takes into account that the radial clearance is reduced due to expansion when the inner ring is press-fitted onto the tapered seat.
