Spherical Roller Bearings SKF 23038 CCK/C3W33

The SKF 23038 CCK/C3W33 spherical roller bearing compensates for misalignment under heavy radial loads and measures 190 x 290 x 75 mm.

The SKF 23038 CCK/C3W33 self-aligning roller bearing handles high radial and axial loads in demanding industrial applications. As an open roller bearing made from standard 100Cr6 bearing steel, it is suitable for operating temperatures ranging from -30 to +200 degrees. A guided sheet steel cage maintains the correct spacing between the roller sets during operation. Thanks to the combination of a tapered bore, a slightly increased radial clearance (C3) and a lubrication groove with lubrication holes in the outer ring, this bearing unit integrates seamlessly into industrial maintenance and new designs.

In which installation situations does the 23038 CCK/C3W33 self-aligning roller bearing compensate for misalignment?

This design is primarily used for heavy radial loads where elastic deflection of the shaft or misalignment may occur. The two rows of rollers run on a common hollow-spherical outer ring raceway, enabling the bearing to automatically compensate for misalignment between the shaft and housing. This reduces edge pressures on the rolling elements. The open design also allows for flexible integration into existing lubrication systems with external housing seals.

What is the function of the tapered bore and the C3 clearance?

The tapered bore, with a taper ratio of 1:12, allows mounting on tapered shaft seats or, using clamping or withdrawal sleeves, on smooth shafts. When the bearing is pushed onto the shaft, the bearing clearance is specifically reduced. The increased bearing clearance class C3 helps to ensure that sufficient radial clearance remains even after the bearing has become a tight fit and during temperature-induced expansion whilst the bearing is in operation. In addition, the integrated W33 lubrication groove in the outer ring facilitates relubrication during operation.
