Spherical Roller Bearings SKF 22214 E/C3

The SKF 22214 E/C3 self-aligning roller bearing, measuring 70x125x31 mm, provides reliable compensation for shaft deflection whilst offering high radial load-carrying capacity.

The SKF 22214 E/C3 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. It withstands high radial loads and compensates for misalignment between the shaft and housing through angular movement. Manufactured from standard 100Cr6 rolling bearing steel and featuring a sheet steel cage, this open bearing withstands temperatures ranging from -30 to +200 degrees. An integrated lubrication groove with lubrication holes on the outer ring facilitates continuous relubrication whilst the bearing is in operation.

Under what conditions is the 22214 E/C3 self-aligning roller bearing used?

It is primarily used under high radial loads, where shaft deflection or misalignment needs to be compensated for. Thanks to the angular contact design, the spherical rollers compensate for misalignment between the inner and outer rings. The open design allows lubricant to be applied directly to the rolling elements and raceways. The operating temperature range of –30 to +200 degrees enables use under fluctuating process temperatures.

What are the key features of the version with C3 bearing clearance and P5 running accuracy?

The slightly increased factory-set radial bearing clearance (C3) provides the rollers with sufficient radial play should the inner and outer rings heat up to different degrees during operation or should tight fits reduce the bearing clearance. At the same time, the increased running accuracy to class P5, combined with standard dimensional accuracy PN, contributes to low-vibration operation. The design must include a suitable housing seal to keep contaminants away from the raceways of the open bearing.
