Spherical Roller Bearings SKF 23952 CC/W33

The SKF 23952 CC/W33 open spherical roller bearing combines dimensions of 260 × 360 × 75 mm with enhanced P5 running accuracy and a lubrication groove for demanding heavy-duty applications.

The 23952 CC/W33 self-aligning roller bearing is an open, double-row roller bearing from SKF designed for heavy radial and combined axial loads. With a bore of 260 mm, an outside diameter of 360 mm and a width of 75 mm, this design automatically compensates for misalignment and shaft deflection during operation. Manufactured from standard rolling-bearing steel (100Cr6), the bearing is suitable for a temperature range of -30 to +200 degrees. The integrated sheet steel cage guides the rolling elements with low vibration during operation.

What is the 23952 CC/W33 self-aligning roller bearing suitable for?

This double-row large-size bearing is designed for heavy-duty mechanical applications involving large shaft diameters, where shaft deflection may occur. Thanks to the hollow-spherical outer ring raceway, the rolling element system self-aligns and compensates for misalignment between the shaft and housing without generating edge pressures. The design accommodates high radial loads as well as axial loads in both directions. As an open bearing, the unit requires integration into external lubrication systems.

What are the advantages of a lubrication groove and P5 running accuracy?

The suffix W33 denotes a circumferential lubrication groove with lubrication holes in the outer ring. The lubricant flows directly between the two rows of rollers via this lubrication channel. Whilst the dimensional accuracy corresponds to the standard PN class, the tighter running accuracy of class P5 offers improved concentricity during operation. With this open design, a suitable external housing seal is required to prevent lubricant loss and the ingress of contaminants.
