Spherical Roller Bearings SKF 23222 CC/W33

The SKF 23222 CC/W33 self-aligning roller bearing, with a bore diameter of 110 mm, offers high load-carrying capacity and compensates for misalignment thanks to its spherical raceways.

The SKF 23222 CC/W33 self-aligning roller bearing is a double-row roller bearing designed for heavy mechanical loads. With key dimensions of a 110 mm bore, 200 mm outer diameter and a width of 69.8 mm, this design is suitable for demanding shaft mountings. The barrel-shaped rollers compensate for angular misalignment between the inner and outer rings. Manufactured from standard rolling bearing steel 100Cr6, this rolling bearing retains its dimensional stability within a temperature range of -30 to +200 degrees.

What loads can the 23222 CC/W33 self-aligning roller bearing accommodate?

This design accommodates high radial forces whilst simultaneously compensating for misalignment and elastic deflection of the shaft. The symmetrical CC rollers contribute to smooth rolling behaviour on the raceways. Thanks to its standard radial clearance, the bearing is particularly suitable for operating conditions involving moderate thermal expansion of the shaft. It is primarily intended for use in heavy-duty bearing arrangements where component deflection must be compensated for by the design.

What is the function of the lubrication groove and P5 running accuracy?

The designation W33 indicates an annular lubrication groove with lubrication holes in the outer ring. This design facilitates relubrication whilst the bearing is installed, as fresh lubricant can reach directly between the rows of rollers. The increased running accuracy to tolerance class P5 reduces runout error, which contributes to smooth running and a reduced tendency to vibrate. As this is an open bearing, ensure that the housing system and external seals are suited to the ambient conditions.
