Spherical Roller Bearings SKF 23234 CC/C3W33

The SKF 23234 CC/C3W33 spherical roller bearing features a 170 mm bore, increased C3 clearance and compensates for misalignment under heavy radial loads.

The SKF 23234 CC/C3W33 self-aligning roller bearing is an open roller bearing designed for demanding bearing applications in mechanical and plant engineering. With key dimensions of a 170 mm bore diameter, 310 mm outer diameter and 110 mm width, this bearing type can withstand very high radial forces whilst also tolerating axial loads in both directions. Manufactured from standard roller bearing steel (100Cr6) with a sheet steel cage, this design is rated for operating temperatures ranging from –30 to +200 degrees.

What is the 23234 CC/C3W33 self-aligning roller bearing suitable for?

This self-aligning roller bearing is primarily used in applications involving high radial loads combined with misalignment or shaft deflection. Thanks to the hollow spherical raceway in the outer ring, the bearing automatically adjusts to angular misalignments between the shaft and housing. This prevents the build-up of excessive edge stresses. The open design allows for direct relubrication via the existing lubrication groove in the outer ring whilst the bearing is in operation.

What are the advantages of C3 clearance and W33 lubrication?

The version with bearing clearance class C3 has increased radial clearance compared with standard clearance. This counteracts the risk of the rolling elements becoming jammed if operational heating or tight fits cause the inner ring to expand. The W33 feature provides the outer ring with an integrated lubrication groove with lubrication holes. This facilitates targeted relubrication and distributes the lubricant evenly across the roller sets. The running accuracy to tolerance class P5 also ensures smooth, low-vibration operation.
