Spherical Roller Bearings SKF 22334 CC/C3W33

The 22334 CC/C3W33 spherical roller bearing from SKF Rolling Bearings, with dimensions of 170 × 360 × 120 mm, is designed to support heavy radial and axial loads.

The 22334 CC/C3W33 self-aligning roller bearing is an open roller bearing made from standard bearing steel (100Cr6) for demanding industrial applications. Two symmetrical rows of rollers and the hollow-spherical raceway of the outer ring enable the compensation of misalignment or shaft deflection during operation. With a sheet steel cage and a design suitable for temperatures ranging from -30 to +200 degrees, this SKF bearing covers a wide range of applications in mechanical engineering.

What is the 22334 CC/C3W33 self-aligning roller bearing suitable for?

Design engineers and maintenance personnel prefer to use this bearing type in heavily loaded shaft mountings subject to combined forces and deflections. Thanks to its angularly adjustable design, the roller bearing dynamically compensates for unavoidable misalignments between the inner and outer rings. The open design allows for the free circulation of oil or grease. The integrated lubrication groove and lubrication holes in the outer ring facilitate rapid relubrication, which simplifies maintenance intervals in industrial plants.

What do the designations C3, W33 and running accuracy P5 mean in practice?

This design features a sheet steel cage for stable roller guidance. The suffix C3 indicates a slightly increased radial bearing clearance. This additional radial clearance is advisable in the presence of thermal stresses or tight fits, to prevent the bearing from being subjected to undesirable preload. The W33 designation refers to lubrication grooves and lubrication holes in the outer ring. The design is complemented by the tolerance class with normal dimensional accuracy (PN) and increased running accuracy (P5) for smooth concentricity.
