Spherical Roller Bearings SKF 23132 CC/W33

The SKF 23132 CC/W33 self-aligning roller bearing, with a 160 mm bore, offers high load-carrying capacity for heavy radial and axial loads under shaft deflection.

The SKF 23132 CC/W33 self-aligning roller bearing is a double-row roller bearing made from standard bearing steel (100Cr6) for demanding industrial applications. Thanks to the hollow-spherical outer ring raceway, this design automatically compensates for misalignment and shaft deflection during operation. The open bearing has main dimensions of 160x270x86 mm, a sheet steel cage and is designed for a temperature range of -30 to +200 degrees.

Under what load conditions is the 23132 CC/W33 self-aligning roller bearing used?

This bearing design is intended for heavy-duty industrial applications where combined radial and axial loads act simultaneously on the shaft. As the barrel rollers are guided in the outer ring with adjustable angular misalignment, the component accommodates elastic deflections and misalignments without causing excessive edge pressure. This reduces the risk of premature wear on the raceways and promotes uniform concentricity under varying operating conditions in industrial machinery.

What are the characteristics of P5 running accuracy and W33 lubrication groove?

The suffix W33 denotes a circumferential lubrication groove with lubrication holes in the outer ring. This design facilitates relubrication whilst the bearing is installed, as the lubricant enters the rolling space directly between the rows of rollers. Furthermore, this variant combines standard dimensional accuracy (PN) with a restricted running accuracy in accordance with tolerance class P5. The standard radial bearing clearance is designed for standard fit conditions between the shaft and housing without significant temperature differences.
