Spherical Roller Bearings SKF 24044 CC/W33

The SKF 24044 CC/W33 self-aligning roller bearing, with a 220 mm bore, compensates for shaft deflection and accommodates heavy radial loads.

The SKF 24044 CC/W33 self-aligning roller bearing is a double-row roller bearing designed for heavy mechanical loads. With main dimensions of 220 × 340 × 118 mm, this rolling bearing is suitable for industrial applications where high radial forces act on the shaft. The hollow spherical raceway in the outer ring allows the bearing to self-align. The roller set automatically compensates for misalignment and elastic deflection of the shaft during operation. You receive an open bearing made from 100Cr6 rolling bearing steel in the SKF Explorer design.

What is the 24044 CC/W33 self-aligning roller bearing suitable for in operation?

This bearing design is primarily used in heavy-duty industrial drives and shaft mountings where high combined loads occur. As shafts can yield elastically under radial and axial forces, the self-aligning bearing compensates for misalignment and reduces edge pressures at the ends of the rollers. With a temperature range of –30 to +200 degrees, the component withstands thermal fluctuations during operation. The open design allows for flexible lubrication with grease or oil via the customer-supplied lubrication system.

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

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. Maintenance personnel can apply lubricant directly between the roller rings, which facilitates relubrication whilst the bearing is in operation. At the same time, the combination of standard dimensional accuracy PN and increased running accuracy P5 ensures smooth running characteristics and low radial runout. A sheet steel cage is used to guide the rolling elements. When designing the system, it must be borne in mind that the open bearing requires an external housing seal to protect against contamination.
