Spherical Roller Bearings SKF 23140 CC/C3W33

The SKF 23140 CC/C3W33 spherical roller bearing, with dimensions of 200 × 340 × 112 mm, can accommodate high radial loads and compensates for misalignment during operation.

The 23140 CC/C3W33 self-aligning roller bearing is an open roller bearing made from standard bearing steel (100Cr6) with a bore of 200 mm, an outer diameter of 340 mm and a width of 112 mm. This SKF product is characterised by its spherical rollers and the hollow-spherical outer ring raceway. As a result, the design compensates for both static and dynamic angular misalignments between the shaft and housing. Under heavy loads, the bearing ensures smooth running across a temperature range of -30 to +200 degrees.

What loads can the 23140 CC/C3W33 self-aligning roller bearing accommodate?

This self-aligning roller bearing is used in applications where significant radial forces and combined axial loads occur. Thanks to its design, the bearing compensates for operational shaft deflection without causing excessive edge pressure. The sheet steel cage guides the rolling elements precisely between the flanges. As the open bearing is designed for demanding environments, its operation requires a suitable housing seal and regular relubrication.

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

The CC/C3W33 design features a slightly increased radial clearance (C3) and a lubrication groove with lubrication holes in the outer ring. The increased radial clearance compensates for thermal expansion caused by operating heat or tight fits, ensuring that the rollers do not become distorted. The W33 feature allows lubricant to be introduced directly between the rows of rollers, which facilitates relubrication during operation. The tolerance class combines dimensional accuracy PN with increased running accuracy P5 for improved concentricity.
