Spherical Roller Bearings SKF 23230 CC/W33

The SKF 23230 CC/W33 spherical roller bearing, measuring 150 × 270 × 96 mm, offers a high load-carrying capacity and automatically compensates for misalignment.

This double-row 23230 CC/W33 self-aligning roller bearing from SKF is designed for heavy radial loads as well as combined axial forces in both directions. Thanks to the hollow spherical raceway in the outer ring, the bearing automatically adjusts to load-induced shaft deflection or misalignment. Manufactured from standard rolling-bearing steel 100Cr6, the design is suitable for a temperature range of -30 to +200 degrees. With a bore of 150 mm, an outer diameter of 270 mm and a width of 96 mm, this roller bearing is suitable for demanding industrial bearing applications.

In which applications does the self-aligning roller bearing compensate for misalignment?

The bearing compensates for manufacturing-related housing misalignment and elastic shaft deflection without generating additional internal constraint forces. In industrial applications with high radial loads, the open design allows for targeted lubrication via the surrounding bearing housing. The integrated sheet steel cage guides the symmetrical rollers precisely within the raceways and maintains a uniform distance between them, even under varying operating conditions.

What is the function of P5 running accuracy and the W33 lubrication groove?

The suffix W33 denotes an annular lubrication groove and lubrication holes in the outer ring, allowing grease or lubricating oil to be applied directly into the bearing interior during maintenance work. In addition to the standard dimensional accuracy PN, this design is characterised by a tighter running accuracy of tolerance class P5. This reduces the radial runout error at normal radial bearing clearance and ensures smooth running of the mounted shaft.
