Spherical Roller Bearings SKF 22234 CCK/C3W33

The SKF 22234 CCK/C3W33 self-aligning roller bearing, with a 170 mm bore, tapered seat and C3 clearance, offers high load-carrying capacity for heavy-duty industrial applications.

The SKF 22234 CCK/C3W33 self-aligning roller bearing accommodates high radial loads as well as simultaneously acting axial forces in both directions. With key dimensions of a 170 mm bore diameter, 310 mm outer diameter and 86 mm width, this open roller bearing is designed for demanding shaft mountings. Thanks to its angularly adjustable design, the bearing automatically compensates for misalignment or shaft deflection during operation. Manufactured from standard 100Cr6 rolling bearing steel, the rolling elements and raceways offer high wear resistance.

In which operating conditions does the 22234 CCK/C3W33 self-aligning roller bearing prove its worth?

This double-row roller bearing is suitable for heavy-duty shaft mountings subject to combined loads and deflection. Thanks to the integrated sheet steel cage and the temperature range of –30 to +200 degrees, the design operates reliably even under thermal stress. As the open bearing has no seals, it can be flexibly integrated into the customer’s lubrication systems. The lubricant is fed directly between the two sets of rollers via the lubrication groove with lubrication holes in the outer ring.

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

The designation CCK refers to the tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats or using clamping and withdrawal sleeves. The slightly increased radial bearing clearance (C3) compensates for the reduction in radial clearance that occurs when the inner ring is pressed onto the shaft. Furthermore, this bearing clearance accounts for operational temperature differences between the inner and outer rings. This design combines PN dimensional accuracy with the increased running accuracy of P5 for smooth running.
