Spherical Roller Bearings SKF 23226 CCK/W33

The SKF 23226 CCK/W33 self-aligning roller bearing (130x230x80 mm) combines a tapered bore with a W33 lubrication groove and enhanced P5 running accuracy for heavy radial loads.

The 23226 CCK/W33 self-aligning roller bearing from SKF is designed for demanding applications involving high radial forces. Thanks to its double-row barrel rollers, the design automatically compensates for misalignment and shaft deflection during operation. The open bearing, made from standard 100Cr6 rolling-element steel, is suitable for a temperature range of -30 to +200 degrees. The integrated sheet steel cage guides the rolling elements with minimal vibration and withstands mechanical stresses during continuous industrial operation.

What is the 23226 CCK/W33 self-aligning roller bearing suitable for?

This roller bearing is used wherever heavy radial loads occur and misalignment between the housing and shaft needs to be compensated for. Applications include heavily loaded industrial applications involving combined forces and demanding operating conditions. The open bearing design allows for flexible lubricant selection and facilitates integration into existing lubrication systems, whilst the design accommodates axial forces in both directions.

What are the advantages of the tapered bore and the W33 designation?

The suffix ‘K’ denotes the tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats or using suitable clamping and withdrawal sleeves. The W33 designation refers to a circumferential lubrication groove with lubrication holes in the outer ring. This allows grease or lubricating oil to be directed precisely between the two rows of rollers. In combination with dimensional accuracy PN and running accuracy P5, the bearing assembly achieves precise concentricity.
