Spherical Roller Bearings SKF 22334 CC/W33

The SKF 22334 CC/W33 spherical roller bearing, with a 170 mm bore and an outer diameter of 360 mm, offers high load-carrying capacity for heavy radial and axial loads.

The 22334 CC/W33 self-aligning roller bearing is an open roller bearing designed for demanding industrial applications where shaft deflection or misalignment may occur. SKF manufactures this version from standard 100Cr6 bearing steel with dimensions of 170 x 360 x 120 mm. As a model in the Explorer series, the bearing features a sheet steel cage and standard radial clearance. The design covers a temperature range from –30 to +200 degrees and is designed for continuous use in mechanical engineering.

What loads can the 22334 CC/W33 self-aligning roller bearing accommodate?

This double-row bearing automatically compensates for misalignment and shaft deflection during operation. The 22334 CC/W33 self-aligning roller bearing accommodates high radial forces whilst reliably absorbing axial forces in both directions. The design, which does not feature an integrated seal, allows for a continuous supply of grease or lubricating oil via external bearing housings, thereby minimising friction and heat build-up under heavy loads.

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

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This enables direct and uniform relubrication of the rolling elements during operation. Combined with the increased running accuracy of tolerance class P5, the rolling elements operate with particularly low vibration, whilst the dimensional accuracy PN facilitates standardised installation in machined housing seats. The dimensions 170 x 360 x 120 mm are relevant for the design.
