Spherical Roller Bearings SKF 22324 CC/W33

The SKF 22324 CC/W33 self-aligning roller bearing, measuring 120 × 260 × 86 mm, accommodates heavy radial loads and reliably compensates for misalignment.

The SKF 22324 CC/W33 self-aligning roller bearing belongs to the Explorer performance class and withstands high combined loads in industrial plant. Thanks to its crowned rollers and the hollow-spherical outer ring raceway, the bearing automatically adjusts itself in the event of shaft deflection. The sheet steel cage guides the rolling elements, whilst the standard rolling bearing steel 100Cr6 enables operation in a temperature range from -30 to +200 degrees.

Under what operating conditions does the bearing compensate for misalignment?

This rolling bearing is suitable for heavily loaded industrial drives and heavy machinery where misalignment or elastic shaft deflection occurs. The double-row roller arrangement transmits considerable radial forces as well as simultaneously acting axial forces in both directions without causing any significant additional friction. The open design allows for the flexible use of grease or lubricating oil and facilitates integration into external lubrication systems where bearing support distances are large.

What are the functions of the lubrication groove and P5 running accuracy?

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This design directs lubricant directly between the rows of rollers, which facilitates relubrication during operation. Dimensional accuracy complies with standard class PN, whilst running accuracy is manufactured to tolerance class P5. This tighter running tolerance reduces vibrations and promotes uniform concentricity at rated speeds.
