Spherical Roller Bearings SKF 22324 CC/C3W33

The SKF 22324 CC/C3W33 self-aligning roller bearing, with dimensions of 120 × 260 × 86 mm, C3 clearance and a W33 lubrication groove, provides reliable guidance under high radial loads.

As a double-row roller bearing, the SKF 22324 CC/C3W33 self-aligning roller bearing accommodates very heavy radial and combined axial forces. Thanks to the hollow-spherical outer ring raceway, this design automatically compensates for misalignment and shaft deflection during operation. The open bearing is made from standard rolling-element bearing steel (100Cr6) and operates within a temperature range of -30 to +200 degrees Celsius. Fitted with a sheet steel cage, it is suitable for demanding industrial drives and heavy machinery applications.

In which applications does the 22324 CC/C3W33 self-aligning roller bearing prove its worth?

This bearing is primarily used in demanding applications involving heavy radial loads and combined axial forces, where high loads act on shafts with a diameter of 120 mm. The barrel roller geometry compensates for misalignment between the inner and outer rings by allowing angular movement, without causing an excessive increase in friction. The open design, without an integrated seal, allows for direct integration into centralised oil circulation or grease lubrication systems during continuous operation.

What do the designations C3, W33 and P5 mean for your bearing selection?

The designation C3 indicates a slightly increased radial bearing clearance. This additional clearance accommodates thermal expansion at operating temperatures up to +200 degrees or tight fits without the bearing becoming stressed. The designation W33 indicates a lubrication groove with lubrication holes in the outer ring, which simplifies targeted relubrication within the housing. In addition, the running accuracy to tolerance class P5 with dimensional accuracy PN ensures smooth, low-vibration running of the rolling elements.
