Spherical Roller Bearings SKF 22218 E/C3

The SKF 22218 E/C3 self-aligning roller bearing, measuring 90x160x40 mm and featuring increased C3 clearance, offers high load-carrying capacity in the event of misalignment.

As a double-row roller bearing, the 22218 E/C3 self-aligning roller bearing accommodates very high radial forces as well as axial forces on both sides. Thanks to the barrel-shaped rollers on the spherical outer ring raceway, the bearing automatically compensates for shaft misalignment. As an open component made from 100Cr6 roller bearing steel, it is designed for operating temperatures ranging from -30 to +200 degrees. A sturdy sheet steel cage guides the roller sets precisely and ensures smooth running during continuous operation.

What is the 22218 E/C3 self-aligning roller bearing suitable for?

This self-aligning roller bearing is used where heavy loads act on shafts and where deflection or misalignment may occur. Typical applications include mechanical drives and heavy-duty bearings subjected to high radial and axial loads. Thanks to the lubrication groove with integrated lubrication holes in the outer ring, lubricant can be fed directly into the interior of the bearing. This ensures an even supply to the contact surfaces and simplifies maintenance in industrial operations.

What do C3 bearing clearance and tolerance class P5 mean for your application?

The version with a slightly increased radial clearance (C3) offers more operating clearance than the standard clearance. This is advantageous when temperature differences between the shaft and housing lead to thermal expansion of the inner ring. The dimensional accuracy complies with the standard tolerance PN, whilst the increased running accuracy of class P5 promotes low-vibration concentricity. This open design requires a housing construction with external sealing and regular relubrication.
