Spherical Roller Bearings SKF 23124 CC/W33

The SKF 23124 CC/W33 self-aligning roller bearing, with dimensions of 120x200x62 mm and P5 precision, offers reliable load-carrying capacity under heavy radial loads.

The 23124 CC/W33 self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications. It accommodates high radial forces as well as combined axial forces and compensates for misalignment between the shaft and housing through angular movement. Manufactured from standard 100Cr6 rolling bearing steel and featuring a sheet steel cage, this design is rated for operating temperatures ranging from –30 to +200 degrees. The open bearing allows for direct lubricant supply whilst the bearing is in operation.

What is the 23124 CC/W33 self-aligning roller bearing suitable for?

This roller bearing is particularly suitable for heavy machinery with shaft diameters of 120 mm, where shaft deflection or misalignment may occur during operation. Typical applications include heavy-duty industrial drives, conveyor technology and large rotating units. Thanks to its internal geometry, the bearing dynamically compensates for angular misalignment without causing an excessive increase in friction. This protects adjacent machine components and ensures smooth running characteristics under high radial loads.

What role do P5 running accuracy and the W33 groove play?

The combination of standard dimensional accuracy (PN) and increased running accuracy in tolerance class P5 reduces runout error during operation. This minimises vibrations and running irregularities at medium to high speeds. The suffix W33 denotes a circumferential lubrication groove with lubrication holes in the outer ring. Maintenance personnel use this to apply fresh lubricant symmetrically and directly between both rows of rollers, which facilitates the distribution of the lubricating film inside the bearing.
