Spherical Roller Bearings SKF 23224 CC/C3W33

The SKF 23224 CC/C3W33 self-aligning roller bearing combines dimensions of 120 × 215 × 76 mm with a C3 clearance and a lubrication groove for heavy-duty industrial applications.

The SKF 23224 CC/C3W33 self-aligning roller bearing is a double-row roller bearing designed for applications involving high radial loads and simultaneous axial forces. The outer ring’s spherical raceway can compensate for both static and dynamic misalignment of the shaft. Manufactured from standard 100Cr6 rolling-element bearing steel, the open version features a sheet steel cage. With dimensional accuracy to PN class and running accuracy to tolerance class P5, the bearing is suitable for demanding guidance applications.

What is the 23224 CC/C3W33 self-aligning roller bearing suitable for?

This self-aligning roller bearing is primarily used in shaft mountings subject to high combined loads, where elastic deflection or misalignment may occur under load. The open design allows for free lubricant circulation. The permissible temperature range extends from –30 to +200 degrees Celsius, making the component suitable for both cold environments and operating conditions subject to thermal stress.

What are the advantages of the C3 bearing clearance and the W33 designation?

The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This clearance helps to prevent the bearing from becoming stressed when the shaft heats up or in the case of tight fits. The W33 feature denotes a lubrication groove with lubrication holes in the outer ring. Maintenance personnel use this route to apply lubricant directly between the roller sets. This promotes even lubricant distribution and simplifies service intervals.
