Spherical Roller Bearings SKF 22222 EK

The SKF 22222 EK self-aligning roller bearing (110x200x53 mm) withstands high radial loads and compensates for misalignment during operation.

This double-row 22222 EK self-aligning roller bearing combines a high radial load-carrying capacity with the ability to compensate for misalignment and shaft deflection. Manufactured from standard rolling-element bearing steel (100Cr6), this open bearing is suitable for demanding mechanical assemblies. The integrated sheet steel cage guides the symmetrical barrel rollers along their raceways. Thanks to SKF’s Explorer design, featuring standard dimensional accuracy PN and running accuracy P5, the design ensures smooth running even under high loads.

What loads does the 22222 EK self-aligning roller bearing accommodate during operation?

The bearing is primarily designed for heavy radial loads and shock loads, such as those encountered in shaft mountings prone to deflection. Thanks to the spherical raceway of the outer ring, the 22222 EK self-aligning roller bearing compensates for misalignment between the inner and outer rings, thereby counteracting edge stresses. The permissible temperature range is from -30 to +200 degrees Celsius. Lubricant is fed directly between the sets of rollers via the circumferential lubrication groove and the lubrication holes in the outer ring.

What characteristics does the tapered bore offer in terms of assembly and fit?

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats or use in conjunction with a suitable adapter sleeve on cylindrical shafts. The remaining radial bearing clearance can be adjusted by axially sliding the inner ring. As this is an unsealed bearing, the bearing housing requires external sealing as well as grease or oil lubrication as required.
