Spherical Roller Bearings SKF 23224 CCK/W33

The SKF 23224 CCK/W33 self-aligning roller bearing (120x215x76 mm) withstands high radial loads and compensates for misalignment via its spherical rollers.

The SKF 23224 CCK/W33 self-aligning roller bearing is a rolling bearing designed for demanding industrial applications involving combined loads. Manufactured from standard 100Cr6 bearing steel, the Explorer version offers enhanced performance in a compact design. Two symmetrical rows of rollers and the hollow-spherical outer ring raceway enable self-alignment during operation. The open bearing is suitable for operating temperatures ranging from –30 to +200 degrees Celsius and can be flexibly integrated into existing lubrication systems.

In which applications is the 23224 CCK/W33 self-aligning roller bearing used?

This self-aligning roller bearing is primarily suitable for designs subject to high radial forces where operational shaft deflection or misalignment must be compensated for. Typical operating conditions include mechanical bearing arrangements subject to alternating shock loads or shaft misalignment. Thanks to its PN dimensional accuracy and increased running accuracy in accordance with tolerance class P5, the bearing ensures smooth, low-vibration operation. The open design requires a suitable housing concept with external sealing to protect against contamination and moisture.

What are the advantages of the tapered bore and the relubrication groove on the 23224 CCK/W33?

The tapered internal bore with a taper ratio of 1:12 facilitates mounting on a mounting or withdrawal sleeve, as well as directly onto a tapered shaft seat. This allows the standard radial bearing clearance to be precisely adjusted during press-fitting. The designation W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This feature directs grease or lubricating oil directly between the rows of rollers, which aids targeted relubrication and helps to maintain the contact surfaces.
