Spherical Roller Bearings SKF 22222 E/C3

The SKF 22222 E/C3 self-aligning roller bearing, with a bore of 110 mm, an outside diameter of 200 mm and a C3 clearance, offers high load-carrying capacity under shaft deflection.

The SKF 22222 E/C3 self-aligning roller bearing is a double-row roller bearing designed for demanding mechanical loads in mechanical engineering. With an inner diameter of 110 mm, an outer diameter of 200 mm and a width of 53 mm, this roller bearing accommodates high radial forces and combined axial forces. The barrel-shaped rollers run on a common hollow spherical outer ring raceway. This geometry automatically compensates for misalignment or elastic shaft deflection during operation without causing additional edge pressure.

What is the 22222 E/C3 self-aligning roller bearing suitable for in cases of shaft deflection?

This bearing design is particularly useful where shaft deflection or misalignment occurs between the bearing locations. The component compensates for both static and dynamic angular misalignments directly within the rolling element set. As this bearing is of an open design, lubrication is applied externally. A lubrication groove with lubrication holes in the outer ring directs grease or oil directly to both rows of rollers, which facilitates relubrication during maintenance.

What is the function of the C3 bearing clearance and tolerance class P5?

The C3 designation defines an increased radial clearance compared with the standard version. This clearance is necessary when thermal expansion occurs due to tight fits or temperature differences between the inner and outer rings. The component is designed for a temperature range of -30 to +200 degrees. In addition, the design combines dimensional accuracy class PN with running accuracy class P5. A sheet steel cage guides the rolling elements on the raceways made of 100Cr6 roller bearing steel.
