Spherical Roller Bearings SKF 23060 CCK/C3W33

The SKF 23060 CCK/C3W33 spherical roller bearing, measuring 300 × 460 × 118 mm, with a tapered bore and C3 clearance, compensates for shaft deflection under heavy loads.

The SKF 23060 CCK/C3W33 self-aligning roller bearing is an open rolling bearing designed for demanding industrial applications involving high mechanical loads. With a bore diameter of 300 mm, an outer diameter of 460 mm and a width of 118 mm, the design accommodates high radial and axial forces on both sides. Thanks to the hollow-spherical outer ring raceway, the bearing compensates for misalignment and elastic deflection of the shaft during operation. A sheet steel cage guides the symmetrical rollers evenly along the raceways.

In which applications is the 23060 CCK/C3W33 spherical roller bearing used?

This design is primarily used in industrial bearing arrangements where shafts are prone to deflection under load or where there are angular misalignments resulting from the manufacturing process. Thanks to the open design and the lubrication groove with lubrication holes on the outer ring (W33), lubricant can be applied precisely from the outside. This facilitates regular relubrication whilst the bearing is installed, without the need for time-consuming disassembly of the housing.

What is the function of the tapered bore and the C3 clearance?

The tapered bore with a 1:12 taper allows for precise mounting on tapered shaft seats as well as with clamping or withdrawal sleeves. Axial press-fitting causes the inner ring to expand, thereby reducing the radial bearing clearance. The increased C3 bearing clearance compensates for this installation shrinkage as well as operational thermal expansion within a temperature range of -30 to +200 degrees, ensuring that the bearing continues to run freely.
