Spherical Roller Bearings SKF 24040 CC/C3W33

The SKF 24040 CC/C3W33 spherical roller bearing, measuring 200 × 310 × 109 mm, compensates for misalignment and can handle very heavy radial loads.

The 24040 CC/C3W33 self-aligning roller bearing is an open, double-row roller bearing designed for heavy-duty industrial applications. Thanks to the spherical outer ring raceway, the bearing can adjust its angle to accommodate shaft deflection or misalignment. Manufactured from standard roller bearing steel (100Cr6) with a sheet steel cage, the design is rated for operating temperatures from -30 to +200 degrees. This version combines standard dimensional accuracy (PN) with enhanced running accuracy to tolerance class P5.

What requirements does the 24040 CC/C3W33 spherical roller bearing meet?

The self-aligning roller bearing is primarily used in heavy-duty shaft mountings where high radial forces and shock loads occur. Thanks to its design, the bearing compensates for misalignment between the housing and the shaft directly during operation. In addition to primarily radial forces, the design also accommodates axial guidance forces in both directions. As this is an open design, it is intended for operation within a lubricated and externally sealed housing.

What do the designations C3 and W33 mean?

The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional clearance helps to prevent the bearing from becoming seized if operational heating or tight fits cause the rings to expand radially. The W33 designation indicates a circumferential lubrication groove with lubrication holes in the outer ring. Lubricant can be applied directly between the rows of rollers via these openings, which improves lubricant distribution within the bearing.
