Spherical Roller Bearings SKF 24034 CC/W33

The SKF 24034 CC/W33 spherical roller bearing, measuring 170 × 260 × 90 mm, offers a high radial load capacity and compensates for angular misalignment during operation.

The 24034 CC/W33 self-aligning roller bearing is an open roller bearing made from standard bearing steel (100Cr6) in the SKF Explorer design. It has a cylindrical bore of 170 mm, an outer diameter of 260 mm and a width of 90 mm. With its standard radial clearance and sheet steel cage, this design is specifically intended for applications where high radial forces act on the shaft and deflection may occur.

What is the 24034 CC/W33 self-aligning roller bearing suitable for?

This bearing is primarily used in mechanical engineering applications where heavy loads must be supported. As the barrel-shaped rollers run on a common hollow spherical outer ring raceway, the design automatically compensates for static and dynamic misalignments between the shaft and housing. The open design covers a temperature range from -30 to +200 degrees and is suitable for bearing locations with demanding thermal environmental conditions.

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

The suffix W33 denotes a circumferential lubrication groove with lubrication holes in the outer ring. This design facilitates relubrication whilst the bearing is installed, as the lubricant enters directly into the interior of the bearing. With dimensional accuracy PN and increased running accuracy in accordance with Class P5, the bearing offers precise concentricity. As this is an open bearing without an integrated seal, an external housing seal is required to protect against contamination.
