Spherical Roller Bearings SKF 23130 CC/W33

The SKF 23130 CC/W33 spherical roller bearing, measuring 150 x 250 x 80 mm, can handle heavy loads and compensates for misalignment.

The 23130 CC/W33 self-aligning roller bearing is an open roller bearing designed for demanding industrial applications involving combined loads. With an inner diameter of 150 mm, an outer diameter of 250 mm and a width of 80 mm, the design can withstand high radial forces. The 100Cr6 material gives the components high dimensional stability. Thanks to the integrated sheet steel cage, the roller sets remain precisely guided even under continuous load. The component is suitable for operating temperatures ranging from -30 to +200 degrees Celsius.

What is the 23130 CC/W33 spherical roller bearing suitable for in operation?

Design engineers select this design primarily for heavy-duty shaft mountings where deflection or misalignment between the housing and the shaft may occur. Thanks to the hollow spherical raceway in the outer ring, the bearing can be adjusted to compensate for angular misalignment. Typical applications are found in general mechanical engineering on shafts subjected to combined loads. As the bearing is open at both ends, it can be flexibly integrated into existing lubrication systems using oil or grease.

What are the advantages of the W33 lubrication groove and tolerance class P5?

The designation W33 denotes an annular lubrication groove with bore holes in the outer ring. This feature facilitates relubrication whilst the bearing is installed, as the lubricant reaches directly between the rows of rollers. In addition to the standard dimensional accuracy PN, this design is characterised by the tighter running accuracy of tolerance class P5. The improved concentricity reduces vibrations in the system and ensures smooth running with normal radial bearing clearance.
