Spherical Roller Bearings SKF 23226 CC/W33

The 23226 CC/W33 self-aligning roller bearing from SKF Rolling Bearings features a 130 mm bore, a 230 mm outer diameter and a width of 80 mm, designed for heavy radial loads.

The 23226 CC/W33 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. This SKF rolling bearing component accommodates high radial loads as well as combined axial forces. Thanks to the spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation. Manufactured from standard 100Cr6 rolling bearing steel, the components possess the necessary dimensional stability for demanding operating conditions.

What is the 23226 CC/W33 self-aligning roller bearing suitable for in operation?

This self-aligning roller bearing is particularly suitable for heavy-duty applications in mechanical and plant engineering where shaft deflection or angular misalignment between the shaft and housing occurs. The design features two symmetrical rows of rollers in a robust sheet steel cage. The open bearing allows operating temperatures ranging from –30 to +200 degrees Celsius and operates reliably in continuously loaded industrial drives when properly lubricated.

What is the function of the W33 lubrication groove and tolerance class P5?

The suffix W33 denotes an annular lubrication groove with lubrication holes in the outer ring. This feature facilitates relubrication whilst the bearing is installed, as the lubricant reaches directly between the two rows of rollers. This design combines standard dimensional accuracy PN with the higher running accuracy P5. This tighter running tolerance reduces radial runout and promotes smooth running with normal radial bearing clearance.
