Spherical Roller Bearings SKF 22216 EK

The SKF 22216 EK spherical roller bearing, with an 80 mm tapered bore and an integrated lubrication groove, offers high load-carrying capacity for demanding industrial applications.

The 22216 EK self-aligning roller bearing is an open rolling bearing in the SKF Explorer performance class. It primarily withstands heavy radial loads whilst also accommodating axial loads in both directions. Thanks to the hollow-spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation. Manufactured from standard 100Cr6 rolling bearing steel, it has a permissible temperature range of -30 to +200 degrees Celsius.

In which applications does the 22216 EK self-aligning roller bearing excel?

Users primarily employ the bearing in industrial applications where high loads are accompanied by misalignment or shaft deflection. The sheet steel cage guides the rollers even under demanding operating conditions. As this is an open design without seals, the bearing can be incorporated into grease- or oil-lubricated housing systems.

What advantages does the tapered bore offer during installation?

The suffix ‘EK’ denotes a tapered bore with a taper ratio of 1:12 and an optimised internal design. Installation is carried out either directly onto a tapered shaft seat or, using a suitable clamping or withdrawal sleeve, onto cylindrical shafts. The remaining radial bearing clearance can be adjusted by axial displacement on the tapered seat. A lubrication groove with lubrication holes in the outer ring ensures targeted delivery of the lubricant.
