Spherical Roller Bearings SKF 22326 CCK/W33

The SKF 22326 CCK/W33 self-aligning roller bearing (130x280x93 mm) compensates for misalignment and withstands heavy radial loads at temperatures up to 200 °C.

The SKF 22326 CCK/W33 self-aligning roller bearing belongs to the Explorer performance class for demanding industrial applications. Two symmetrical rows of rollers carry loads on a common hollow-spherical outer ring raceway, enabling the open bearing to automatically compensate for angular misalignment and shaft deflection during operation. The 100Cr6 material used in manufacture gives the rings and rolling elements high dimensional stability within a temperature range of -30 to +200 degrees.

In which installation situations does the 22326 CCK/W33 self-aligning roller bearing prove its worth?

This design is particularly suitable for heavy-duty applications involving high radial forces and shock loads. Wherever shaft deflection or misalignment between the bearing housings occurs, the oscillating movement reduces mechanical stress within the system. The integrated sheet steel cage guides the two rows of rollers precisely and withstands dynamic accelerations during operation.

What are the advantages of a tapered bore and the W33 design?

The suffix CCK denotes a tapered bore with a ratio of 1:12. This allows direct mounting on a tapered shaft seat or, alternatively, on a cylindrical shaft using suitable mounting and withdrawal sleeves. The remaining radial bearing clearance can be precisely adjusted via the axial slide-on travel. The W33 designation indicates a circumferential lubrication groove with lubrication holes in the outer ring, which facilitates the supply of lubricant directly into the interior of the rolling bearing once it is installed.
