Spherical Roller Bearings SKF 24056 CC/W33

The SKF 24056 CC/W33 spherical roller bearing, measuring 280 × 420 × 140 mm, offers high load-carrying capacity for heavy-duty shaft mountings with angular misalignment.

The 24056 CC/W33 self-aligning roller bearing is an open, double-row roller bearing designed for demanding industrial applications with shaft diameters of 280 mm. The design, made from standard 100Cr6 bearing steel, automatically compensates for misalignment and shaft deflection during operation. Fitted with a robust sheet steel cage and manufactured in the SKF Explorer design, this large bearing is suitable for continuous heavy-duty service within a temperature range of -30 to +200 degrees Celsius. This provides technical buyers and maintenance engineers with a durable solution for compact installation spaces.

What is the 24056 CC/W33 spherical roller bearing suitable for under high loads?

This self-aligning roller bearing is primarily used on heavily loaded large shafts and industrial gearboxes where high radial and axial forces act simultaneously. As shafts can deform elastically under heavy loads, the hollow-spherical outer ring raceway counteracts harmful edge stresses on the roller bodies. The operating temperature range of -30 to +200 degrees Celsius allows for operation even in high-heat working environments.

What are the advantages 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 the targeted supply of lubricant directly into the centre of the rolling elements during routine maintenance. In combination with the standard dimensional accuracy PN and the increased running accuracy of class P5, the bearing operates with low vibration and good concentricity even under high radial loads. For designers and fitters, this system simplifies relubrication cycles and ensures even grease distribution.
