Spherical Roller Bearings SKF 23040 CC/C3W33

The SKF 23040 CC/C3W33 self-aligning roller bearing features a 200 mm bore, increased C3 clearance and automatically compensates for misalignment during operation.

The SKF 23040 CC/C3W33 self-aligning roller bearing is a double-row roller bearing made from standard bearing steel (100Cr6) for industrial applications involving high radial loads. Measuring 200 × 310 × 82 mm, this open bearing is used in applications where shaft deflection may occur. Thanks to the spherical outer ring raceway, the roller pack self-aligns during operation. A sturdy sheet steel cage guides the rolling elements, whilst the temperature range of –30 to +200 degrees opens up a wide range of applications in industrial maintenance.

What loads and operating conditions can the 23040 CC/C3W33 self-aligning roller bearing withstand?

This rolling bearing is primarily designed for heavy-duty shaft mountings in mechanical and plant engineering, where significant radial loads and axial forces act simultaneously. Typical applications include situations involving shaft deflection or misalignment. As this is an open design, the construction integrates the bearing into a housing with external lubrication. The P5 precision class ensures smooth running characteristics during continuous operation.

What do C3 bearing clearance and the designation W33 mean?

The designation C3 indicates a slightly increased radial clearance compared with the standard version. It compensates for thermal expansion at higher operating temperatures or with tight fits, ensuring that the roller assembly rotates freely. The suffix W33 refers to a circumferential lubrication groove with lubrication holes in the outer ring. This feature facilitates relubrication whilst the bearing is installed, as the lubricant reaches directly between the two rows of rollers. Before installation, always check the dimensions: 200 mm inner diameter and 310 mm outer diameter.
