Spherical Roller Bearings SKF 23240 CCK/C3W33

The SKF 23240 CCK/C3W33 self-aligning roller bearing, with a 200 mm bore, offers high load-carrying capacity for demanding industrial applications involving misalignment.

The SKF 23240 CCK/C3W33 self-aligning roller bearing accommodates heavy radial loads as well as combined axial forces. Thanks to the hollow spherical outer ring raceway, this design automatically compensates for static and dynamic angular misalignments between the inner and outer rings. As an open rolling bearing made from standard 100Cr6 bearing steel with a sheet steel cage, the component is designed for a temperature range of –30 to +200 degrees. The integrated lubrication system, comprising grooves and bores in the outer ring, facilitates relubrication during operation.

Under what loads does the 23240 CCK/C3W33 self-aligning roller bearing perform well?

This design is suitable for demanding shaft mountings subject to high radial loads and simultaneous axial forces. If elastic shaft deflection or manufacturing-related angular misalignment occurs between the bearing seats, the bearing compensates for these deviations without the need for forced alignment. With main dimensions of 200 × 360 × 128 mm, the component also absorbs uneven impact forces during continuous operation.

What are the advantages of a tapered bore and C3 clearance?

The tapered bore with a taper ratio of 1:12 allows for secure mounting directly onto tapered shaft seats or onto cylindrical shafts using clamping or withdrawal sleeves. When axially slid onto the tapered seat, the radial clearance is measurably reduced, allowing the interference fit to be precisely adjusted. The increased bearing clearance class C3 helps to ensure that sufficient operating clearance is maintained after press-fitting and when the bearing is heated. The W33 feature provides lubricant supply directly into the bearing interior.
