Spherical Roller Bearings SKF 23024 CC/W33

The SKF 23024 CC/W33 spherical roller bearing, measuring 120 × 180 × 46 mm, provides a robust bearing solution for heavy radial loads under shaft deflection.

The 23024 CC/W33 self-aligning roller bearing is an open, double-row roller bearing designed for demanding industrial applications. Its design automatically compensates for misalignment and elastic deflection of the shaft during operation. This bearing, made from 100Cr6 bearing steel, features a pressed sheet steel cage and is designed for an operating temperature range of –30 to +200 degrees. SKF manufactures this version in the Explorer performance class with standard radial clearance.

What is the 23024 CC/W33 self-aligning roller bearing suitable for in industrial plant?

Design engineers primarily select this size for heavy-duty shaft mountings where high radial forces occur and misalignments need to be compensated for. Typical applications include industrial gearboxes and material handling systems. The integrated lubrication groove, together with lubrication holes in the outer ring (designation W33), allows lubricant to be applied directly into the interior of the roller rows. The open design permits operation with both grease and lubricating oil.

What are the distinguishing features of tolerance class P5 and the CC design?

The CC version features window-type sheet steel cages and an inner ring without a guide ring, which reduces friction and aids the formation of a lubricating film. Whilst the dimensional accuracy corresponds to the standard PN class, the bearing has the tighter P5 tolerance class for running accuracy. This promotes smooth shaft rotation at higher speeds. During installation, care must be taken to ensure an external housing seal is fitted, as this is an open bearing without an integrated seal.
