Spherical Roller Bearings SKF 22326 CC/W33

The SKF 22326 CC/W33 self-aligning roller bearing, with dimensions of 130 × 280 × 93 mm, provides a high-load-capacity bearing solution for heavy radial loads and misalignment.

The SKF 22326 CC/W33 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. With a bore of 130 mm, an outer diameter of 280 mm and a width of 93 mm, it accommodates heavy radial loads as well as simultaneously acting axial forces. Thanks to the spherical outer ring raceway, the self-aligning roller bearing automatically compensates for shaft misalignment. As an open bearing made from standard 100Cr6 rolling bearing steel, this version is designed for operating temperatures ranging from -30 to +200 degrees.

What is the 22326 CC/W33 self-aligning roller bearing suitable for?

The 22326 CC/W33 self-aligning roller bearing is particularly suitable for demanding applications where high radial forces and shaft deflection occur. Thanks to its angularly adjustable design, the bearing compensates for misalignment between the inner and outer rings without compromising load-carrying capacity. Operators use this SKF Explorer design in systems where precise guidance and running accuracy to tolerance class P5 are required.

What do the designations CC and W33 mean for this bearing?

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring, which directs lubricant directly into the bearing interior. The designation CC stands for guide-free inner rings and window-type sheet steel cages, which reduce friction and support smooth rolling of the rollers. As this is an open bearing with standard radial clearance, the bearing housing must be protected against the ingress of dirt and relubricated externally in order to utilise the full temperature range from -30 to +200 degrees.
