Spherical Roller Bearings SKF 22230 CC/C3W33

The SKF 22230 CC/C3W33 self-aligning roller bearing, measuring 150 × 270 × 73 mm, withstands heavy radial loads and compensates for shaft misalignment.

The SKF 22230 CC/C3W33 self-aligning roller bearing is a double-row roller bearing designed for demanding mechanical loads. It supports shafts under combined loads and automatically compensates for misalignment between the inner and outer rings. Manufactured from standard 100Cr6 rolling bearing steel and featuring a slightly increased C3 clearance, this design is particularly well-suited to thermal variations during operation. The open design allows for direct lubricant supply via the surrounding housing system.

What loads can the 22230 CC/C3W33 self-aligning roller bearing accommodate?

This self-aligning roller bearing is designed for applications involving heavy radial forces and axial forces acting in both directions. Thanks to its angularly adjustable design, the bearing accommodates elastic shaft deflection and misalignment without generating harmful edge stresses. As it is designed for operating temperatures ranging from –30 to +200 degrees, it retains its dimensional stability even in warm environments. The integrated sheet steel cage guides the rolling elements precisely under continuous, long-term loads.

What are the distinctive features of the CC/C3W33 design and tolerance class P5?

The suffix C3 indicates increased radial bearing clearance compared to the standard. This clearance helps to prevent stress build-up if the shaft heats up more than the housing during operation. The designation W33 describes an integrated lubrication groove with lubrication holes in the outer ring, which facilitates relubrication whilst the bearing is installed. Whilst the dimensional accuracy complies with class PN, the running accuracy to P5 ensures smooth concentricity.
