Spherical Roller Bearings SKF 23244 CC/C3W33

The SKF 23244 CC/C3W33 spherical roller bearing has dimensions of 220 × 400 × 144 mm, a C3 clearance and a lubrication groove for heavy radial loads.

The SKF 23244 CC/C3W33 self-aligning roller bearing is an open roller bearing designed for heavy radial and axial loads. With key dimensions of a 220 mm bore, 400 mm outside diameter and 144 mm width, this design can withstand considerable forces. Two symmetrical rows of rollers automatically compensate for misalignment between the shaft and the housing. The integrated sheet steel cage guides the rolling elements precisely at operating temperatures ranging from -30 to +200 degrees.

In which applications is the 23244 CC/C3W33 self-aligning roller bearing used?

This size is primarily used in bearing arrangements subject to high radial and axial loads, where shaft deflection or misalignment may occur. Thanks to the barrel-shaped design of the rolling elements, the bearing compensates for angular misalignment without inducing residual stresses. Manufacture from standard roller bearing steel 100Cr6 gives the components high compressive strength for operation under heavy loads. For open bearing arrangements, an external housing seal and regular relubrication must be provided for.

What is the function of C3 bearing clearance and the W33 lubrication groove?

The designation C3 indicates a slightly increased radial clearance compared with the standard version. It compensates for thermal expansion at high temperatures as well as interference fits on the shaft and housing. The designation W33 refers to a lubrication groove with lubrication holes in the outer ring, allowing lubricant to reach directly between the rows of rollers. The tolerance class combines increased running accuracy (P5) with dimensional accuracy (PN) to ensure uniform concentricity in the drive train.
