Spherical Roller Bearings SKF 22336 CC/W33

The SKF 22336 CC/W33 spherical roller bearing, measuring 180 × 380 × 126 mm, offers high load-carrying capacity for heavy radial loads in continuous industrial operation.

The 22336 CC/W33 self-aligning roller bearing is an open roller bearing designed for demanding industrial applications involving high combined loads. Manufactured from standard rolling-element bearing steel (100Cr6) in the SKF Explorer design, this type automatically compensates for misalignment and shaft deflection. The design features a cylindrical bore of 180 mm, an outer diameter of 380 mm and a width across flats of 126 mm. With standard radial clearance and a guided sheet steel cage, the bearing is suitable for operating temperatures ranging from -30 to +200 degrees.

In which applications does the 22336 CC/W33 self-aligning roller bearing excel?

This rolling bearing is primarily used in industrial applications where high radial forces and axial loads in both directions occur. Thanks to the spherical outer ring raceway, the bearing accommodates shaft misalignment without edge pressure. The open-type design allows for flexible integration into housing systems with an external lubrication supply.

What are the advantages of the W33 lubrication groove and P5 running accuracy?

The W33 designation indicates an annular lubrication groove with lubrication holes in the outer ring. This feature facilitates relubrication whilst the bearing is installed and distributes the lubricant evenly throughout the rolling element chamber. Furthermore, the bearing meets the tighter running accuracy of tolerance class P5 whilst maintaining standard dimensional accuracy PN. This combination reduces vibrations during operation and ensures smooth running under demanding speed conditions.
