Spherical Roller Bearings SKF 22332 CC/W33

The SKF 22332 CC/W33 spherical roller bearing combines key dimensions of 160 × 340 × 114 mm with P5 running accuracy and a lubrication groove for heavy-duty industrial applications.

The open 22332 CC/W33 self-aligning roller bearing is a double-row roller bearing made from standard 100Cr6 bearing steel for use in demanding conditions. With a bore of 160 mm, an outside diameter of 340 mm and a width of 114 mm, this standard version of the Explorer series accommodates combined loads. This design accommodates operational misalignment of the shaft. Thanks to its wide temperature range of -30 to +200 degrees, the roller bearing remains operational in its intended mounting even in thermally demanding environments.

Under what load conditions does the 22332 CC/W33 self-aligning roller bearing perform well?

This design is intended for bearing arrangements subject to high radial forces and simultaneous axial loads. The design automatically compensates for angular misalignment between the shaft and housing, thereby preventing edge stresses. The integrated sheet steel cage guides the symmetrical rollers even under varying load conditions. In combination with the standard radial clearance, this design helps ensure that drives operate with low friction and smooth running at typical operating temperatures.

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

The designation W33 indicates a circumferential lubrication groove with lubrication holes in the outer ring. This design simplifies relubrication whilst the bearing is installed, as the lubricant is fed directly between the two rows of rollers. In combination with the increased running accuracy to tolerance class P5 and dimensional accuracy PN, this roller bearing is suitable for systems where precise concentricity is essential. When designing the system, users should protect the open design from contamination by using external housing seals.
