Spherical Roller Bearings SKF 22334 CCK/W33

The SKF 22334 CCK/W33 spherical roller bearing, measuring 170 × 360 × 120 mm and featuring a tapered bore, provides reliable compensation for misalignment under heavy loads.

The SKF 22334 CCK/W33 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. It accommodates very high radial loads as well as simultaneously acting axial forces in both directions. Thanks to the hollow-spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation. The Explorer version, made from classic standard rolling-element bearing steel 100Cr6, combines standard dimensional accuracy PN with increased running accuracy to tolerance class P5.

Under what operating conditions does the 22334 CCK/W33 self-aligning roller bearing prove its worth?

This self-aligning roller bearing performs particularly well in heavy-duty applications with high radial loads, where shock loads, vibrations and operational shaft deflection occur. The internal geometry guides the barrel-shaped rollers with low friction, whilst the guided sheet steel cage keeps the rolling elements spaced apart. The component is suitable for operating temperatures ranging from -30 to +200 degrees and is suitable for open bearing arrangements under demanding thermal conditions.

What is the function of the tapered bore and the W33 lubrication groove?

The designation CCK refers to a tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats as well as securing the bearing on cylindrical shafts using a clamping or withdrawal sleeve. Furthermore, the standard radial clearance can be precisely adjusted by axial sliding. The suffix W33 denotes a circumferential lubrication groove with lubrication holes in the outer ring, through which lubricant is fed directly between the two sets of rollers.
