Spherical Roller Bearings SKF 23030 CC/W33

The SKF 23030 CC/W33 spherical roller bearing, measuring 150 × 225 × 56 mm, compensates for misalignment and withstands heavy radial loads.

The SKF 23030 CC/W33 self-aligning roller bearing is a rolling bearing designed for industrial applications involving demanding load conditions. With a bore of 150 mm, an outer diameter of 225 mm and a width of 56 mm, this bearing is particularly suitable for larger shaft mountings. The barrel-shaped rollers run in two rows and compensate for both static and dynamic angular misalignment of the shaft. Manufactured from standard roller bearing steel 100Cr6, the design with a sheet steel cage offers high dimensional stability during operation.

In which installation situations does the 23030 CC/W33 self-aligning roller bearing prove its worth?

This self-aligning roller bearing is used where high radial forces act on rotating shafts and where deflection or misalignment must be compensated for. Such requirements arise primarily in heavily loaded shaft mountings in mechanical engineering, where misalignment can result from manufacturing tolerances or elastic deformation. Thanks to its open design, the bearing can be integrated into housing systems where centralised oil lubrication or defined relubrication intervals using grease are provided.

What is the function of the W33 lubrication groove and the P5 running accuracy?

The W33 designation indicates an annular lubrication groove with lubrication holes in the outer ring. This design facilitates the even supply of lubricant to the raceways directly from the outside, without the need to apply lubricant via the end faces. Furthermore, this bearing combines standard dimensional accuracy PN with the finer running accuracy P5. This combination ensures low-vibration operation and precise shaft guidance at operating temperatures ranging from –30 to +200 degrees Celsius.
