Spherical Roller Bearings SKF 23940 CC/W33

The SKF 23940 CC/W33 spherical roller bearing offers high load-carrying capacity with a 200 mm bore, P5 running accuracy and an integrated lubrication groove for industrial applications.

The SKF 23940 CC/W33 self-aligning roller bearing is an open roller bearing for heavy-duty industrial applications, with a bore of 200 mm, an outer diameter of 280 mm and a width of 60 mm. The design automatically compensates for misalignment and shaft deflection during operation. Manufactured from standard 100Cr6 rolling-bearing steel, the bearing operates within a temperature range of -30 to +200 degrees. The integrated sheet steel cage guides the rollers and withstands mechanical stresses.

What is the 23940 CC/W33 self-aligning roller bearing suitable for?

This self-aligning roller bearing is particularly suitable for heavy-duty applications in general mechanical engineering where high radial loads occur and misalignment must be compensated for. Thanks to its design, the bearing dynamically compensates for misalignment between the inner and outer rings without impairing its function. Design engineers use this design primarily for shaft mountings subject to high radial forces and at risk of deflection. Proper operation is ensured by a targeted supply of lubricant and a stable housing environment.

What are the distinctive features of the CC/W33 and P5 designs?

The W33 design features a circumferential lubrication groove with lubrication holes in the outer ring. This facilitates relubrication whilst the bearing is installed, as the lubricant reaches directly between the roller sets. Another important feature is the tolerance class: whilst the dimensional accuracy corresponds to the standard PN tolerance class, the bearing offers increased running accuracy in accordance with class P5. As an open design with standard radial clearance, the bearing requires a housing seal to be fitted on site during operation.
