Spherical Roller Bearings SKF 23028 CC/W33

The 23028 CC/W33 spherical roller bearing from SKF Rolling Bearings, measuring 140 × 210 × 53 mm, compensates for shaft deflection and withstands heavy radial loads in industrial applications.

The 23028 CC/W33 self-aligning roller bearing belongs to SKF’s proven Explorer performance class and is designed as a double-row spherical roller bearing. With a bore of 140 mm, an outer diameter of 210 mm and a width of 53 mm, this rolling bearing can accommodate very high radial forces. At the same time, the hollow-spherical raceway of the outer ring compensates for misalignment and skewing of the shaft. Manufactured from standard 100Cr6 rolling bearing steel, it can be used in a temperature range from –30 to +200 degrees.

What is the 23028 CC/W33 self-aligning roller bearing suitable for?

This roller bearing is particularly suitable for industrial applications involving high radial forces, where shaft deflection or misalignment occurs. Designs featuring flexible shafts benefit from the self-aligning capability, as this prevents edge pressures on the rollers. In combination with suitable bearing housings, the bearing forms a robust unit for demanding operating environments where continuous radial load-carrying capacity and axial guidance in both directions are required.

What is the function of the suffix W33 and tolerance class P5?

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This allows lubricant to reach directly between the rows of rollers, which facilitates relubrication during operation. As this is an open bearing, you must seal the housing against dirt using external components. The increased running accuracy of class P5 ensures smooth running at normal radial bearing clearance and reduces vibrations at medium speeds.
