Spherical Roller Bearings SKF 22328 CCK/W33

The SKF 22328 CCK/W33 self-aligning roller bearing, with a 140 mm bore, tapered seat and lubrication groove, offers a robust solution for heavy-duty industrial drives.

As a double-row roller bearing, the 22328 CCK/W33 self-aligning roller bearing can accommodate high radial and axial loads. The barrel-shaped rollers run on a common spherical outer ring raceway, which automatically compensates for misalignment and shaft deflection during operation. Manufactured from standard 100Cr6 rolling-bearing steel in the SKF Explorer performance class, this open rolling bearing is designed for heavy-duty machinery where dimensional accuracy and mechanical load-carrying capacity are both essential.

For which loads is the 22328 CCK/W33 self-aligning roller bearing suitable?

This roller bearing is typically used in industrial gearboxes and shaft mountings subject to combined loads. Thanks to its angularly adjustable design, the bearing compensates for misalignment between the shaft and housing without causing additional edge pressures on the rolling elements. The integrated sheet steel cage guides the rollers with dimensional stability and low friction within the permissible temperature range of -30 to +200 degrees Celsius.

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

The suffix ‘K’ denotes a tapered bore with a 1:12 taper ratio, allowing the bearing to be mounted directly onto tapered shaft seats or onto cylindrical shafts using shrink sleeves and withdrawal sleeves. The W33 feature comprises a lubrication groove with lubrication holes in the outer ring, which simplifies targeted relubrication. With standard radial bearing clearance and running accuracy to tolerance class P5, this design is suitable for low-vibration industrial applications.
