Spherical Roller Bearings SKF 23022 CC/W33

The SKF 23022 CC/W33 self-aligning roller bearing, with dimensions of 110 × 170 × 45 mm, can accommodate high radial loads and automatically compensates for misalignment during operation.

The 23022 CC/W33 self-aligning roller bearing is a double-row roller bearing made from standard rolling-element steel (100Cr6). As an open bearing of the SKF Explorer design, this component combines dimensional accuracy in accordance with normal class PN with increased running accuracy in accordance with class P5. A robust sheet steel cage guides the rolling elements precisely between the inner and outer rings.

Under what operating conditions does the 23022 CC/W33 self-aligning roller bearing compensate for misalignment?

Designs featuring long shafts or high radial forces often result in slight misalignment or shaft deflection during operation. Thanks to the hollow spherical raceway of the outer ring, the roller set adjusts with angular movement in response to shaft deflection and misalignment between the housing and the shaft. The open design is intended for installation in lubricated housings at operating temperatures ranging from –30 to +200 degrees Celsius.

What is the function of the W33 lubrication groove and tolerance class P5?

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This design facilitates the supply of lubricant directly to the rolling elements. Tolerance class P5 defines increased running accuracy, which reduces radial runout errors during rotational operation. The design must take into account the standard radial bearing clearance and the cylindrical seat on a shaft with a diameter of 110 mm.
