Spherical Roller Bearings SKF 22212 E/C3

The SKF 22212 E/C3 open self-aligning roller bearing measures 60 × 110 × 28 mm, offers increased C3 clearance and compensates for misalignment during operation.

The SKF 22212 E/C3 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. It accommodates heavy radial loads as well as simultaneously acting axial forces in both directions. Thanks to its barrel-shaped rollers and the hollow-spherical outer ring raceway, the bearing automatically adjusts to shaft deflection. A sheet steel cage guides the rolling elements evenly, whilst the standard bearing steel 100Cr6 ensures the necessary dimensional stability.

In which installation situations does the 22212 E/C3 self-aligning roller bearing compensate for misalignment?

This roller bearing is suitable for bearing arrangements subject to high radial and axial loads, where shaft deflection or misalignment between the shaft and housing occurs. Thanks to its angularly adjustable design, the bearing automatically compensates for misalignment and reduces mechanical stresses. The permissible temperature range is between –30 and +200 degrees Celsius. As this is an open bearing, lubrication is supplied via the housing system.

What characteristics do C3 bearing clearance and P5 running accuracy offer?

The design with a slightly increased radial clearance (C3) prevents the rollers from seizing up should temperature differences arise between the inner and outer rings during operation, or should tight fits reduce the bearing clearance. In addition to the standard dimensional accuracy PN, this version is characterised by a tighter running accuracy in accordance with Class P5. To facilitate the supply of lubricant, the outer ring features an integrated lubrication groove with lubrication holes.
