Spherical Roller Bearings SKF 24122 CC/C4W33

The SKF 24122 CC/C4W33 self-aligning roller bearing (110x180x69 mm) compensates for misalignment and accommodates heavy radial loads under thermal expansion.

The SKF 24122 CC/C4W33 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. It has a cylindrical bore of 110 mm, an outer diameter of 180 mm and a width of 69 mm. Manufactured from standard 100Cr6 rolling bearing steel, the open design operates within a temperature range of -30 to +200 degrees. The integrated lubrication groove with holes in the outer ring facilitates relubrication during operation.

In which operating conditions does the 24122 CC/C4W33 spherical roller bearing prove its worth?

This self-aligning roller bearing absorbs high radial forces and compensates for shaft deflection during operation. Thanks to the hollow-spherical outer ring raceway, the bearing automatically adjusts to misalignment between the shaft and housing. The window-type sheet steel cage guides the symmetrical rollers with low friction. Typical applications include heavy-duty industrial drives and machine mountings where shock-like radial forces occur.

Why is the C4 clearance important for this self-aligning roller bearing?

The version with bearing clearance class C4 has greater radial clearance than standard bearings. This increased bearing clearance is necessary when significant temperature differences arise between the inner and outer rings during operation. If the shaft expands more than the housing, there remains sufficient operating clearance to prevent the rolling elements from becoming jammed. The increased running accuracy to tolerance class P5 also supports low-vibration concentricity at rated speeds.
