Spherical Roller Bearings SKF 24044 CC/C3W33

The SKF 24044 CC/C3W33 self-aligning roller bearing has a bore diameter of 220 mm, an outside diameter of 340 mm and automatically compensates for misalignment during operation.

The SKF 24044 CC/C3W33 self-aligning roller bearing is designed for high radial and combined axial loads. Thanks to the spherical raceway in the outer ring, the double-row set of rollers aligns itself automatically, enabling the roller bearing to compensate for angular misalignment and shaft deflection. Manufactured from 100Cr6 standard roller bearing steel and guided by a sheet steel cage, this open bearing is designed for thermally and mechanically demanding applications.

In which applications does the 24044 CC/C3W33 self-aligning roller bearing prove its worth?

This size is suitable for heavy-duty shaft mountings with high radial loads, where elastic housing deflection or manufacturing-related misalignment occurs. Thanks to its open design, the lubricant reaches the raceways unhindered, which ensures effective lubrication of the contact surfaces during continuous operation. The self-aligning bearing automatically compensates for misalignment between the inner and outer rings, preventing harmful edge pressures from prematurely stressing the roller sets.

What are the functions of the C3 bearing clearance and the W33 feature?

The increased radial bearing clearance (C3) serves to compensate for thermal expansion at high operating temperatures as well as for fits caused by rigid bearing seats. This ensures that the required radial operating clearance is maintained within the specified temperature range of -30 to +200 degrees. The W33 design, featuring a circumferential lubrication groove and lubrication holes in the outer ring, directs fresh lubricant directly into the centre between the two rows of rollers during maintenance.
