Spherical Roller Bearings SKF 23224 CC/W33

The SKF 23224 CC/W33 spherical roller bearing (120x215x76 mm) accommodates heavy combined loads and compensates for misalignment during operation.

The SKF 23224 CC/W33 self-aligning roller bearing is an open roller bearing designed for demanding industrial applications. With a bore of 120 mm, an outer diameter of 215 mm and a width of 76 mm, this bearing accommodates high radial and, at the same time, axial forces. Manufactured from standard roller bearing steel (100Cr6), this design features a sheet steel cage. The permissible temperature range is from –30 to +200 degrees.

What is the 23224 CC/W33 self-aligning roller bearing suitable for?

Design engineers and maintenance technicians prefer to use this bearing in heavy-duty applications where shaft deflection or misalignment may occur. Thanks to the hollow-spherical outer ring raceway, the barrel-shaped rollers self-align, thereby reducing edge stresses. Typical applications can be found in general mechanical engineering and in highly stressed shaft bearings. The standard radial clearance ensures balanced running behaviour during normal operation for standard fits.

What do the suffixes CC, W33 and tolerance class P5 mean?

These additional designations provide information about the design features of this model. The designation W33 indicates a circumferential lubrication groove with holes in the outer ring, through which lubricant is fed directly to the rolling elements. The abbreviation CC refers to window-type sheet steel cages and an inner ring without a guide ring to optimise friction. Whilst the dimensional accuracy corresponds to the standard class PN, the running accuracy P5 offers a tighter concentricity tolerance for low-vibration applications.
