Spherical Roller Bearings SKF 23160 CC/C3W33

The SKF 23160 CC/C3W33 spherical roller bearing, measuring 300 × 500 × 160 mm and featuring a C3 clearance, provides a high-load-capacity bearing solution for heavy-duty shaft guides.

The SKF 23160 CC/C3W33 self-aligning roller bearing is designed for demanding industrial applications involving high radial forces and shock loads. Thanks to the barrel-shaped rollers on the hollow-spherical outer ring raceway, the roller bearing automatically compensates for misalignment and shaft deflection during operation. Manufactured from standard 100Cr6 bearing steel in tolerance class P0/PN, this open design has proven its worth in harsh operating conditions and at ambient temperatures ranging from -30 to +200 degrees.

What is the 23160 CC/C3W33 self-aligning roller bearing suitable for?

This large-diameter roller bearing is primarily used in heavy machinery, industrial gearboxes and large-scale drive systems where significant radial loads and alternating axial forces are present. Designs with long spans utilise the bearing’s angular adjustability, as it compensates for misalignment between the inner and outer rings without causing edge pressure. The component is suitable for bearing arrangements with shafts of 300 mm in diameter under high continuous loads.

What are the advantages of C3 bearing clearance and the W33 lubrication groove?

The suffix C3 indicates a slightly increased radial clearance. This design is useful where operational heating or tight fits on the 300 mm shaft reduce the bearing clearance during operation. The W33 designation indicates an annular lubrication groove with lubrication holes in the outer ring. This allows lubricant in the open bearing to reach the rolling elements and raceways directly. The integrated sheet steel cage guides the rollers evenly and keeps the weight of the rotating components to a moderate level.
