Spherical Roller Bearings SKF 22338 CC/W33

The SKF 22338 CC/W33 open spherical roller bearing, measuring 190 × 400 × 132 mm, accommodates high radial loads as well as misalignment during operation.

The SKF 22338 CC/W33 self-aligning roller bearing is designed for demanding applications in mechanical engineering. Thanks to its barrel-shaped rollers, this design automatically compensates for both static and dynamic misalignments between the shaft and housing. As an open roller bearing made from standard 100Cr6 bearing steel, the unit is suitable for operating temperatures ranging from -30 to +200 degrees. The Explorer version combines dimensional accuracy in accordance with Class PN with enhanced running accuracy in accordance with Class P5.

What is the 22338 CC/W33 self-aligning roller bearing suitable for?

This roller bearing is primarily used where heavy radial forces act on shafts with a diameter of 190 mm and where misalignment may occur. The double-row bearing also accommodates combined loads with moderate axial forces in both directions. Thanks to its angular adjustment capability, the bearing continues to operate even with slight shaft deflection.

What features does the W33 lubrication groove offer?

The W33 designation indicates a ring-shaped lubrication groove with integrated lubrication holes in the outer ring of the bearing. This design feature allows direct relubrication via the bearing housing, without the need to force lubricant past the rolling elements from the side. As a result, grease or oil is distributed evenly across both rows of rollers. In combination with the lightweight sheet-steel cage and the standard radial clearance, this ensures smooth running.
