Spherical Roller Bearings SKF 23148 CC/C3W33

The SKF 23148 CC/C3W33 spherical roller bearing, measuring 240 x 400 x 128 mm, offers reliable load-carrying capacity for heavy radial and axial loads in continuous industrial operation.

The SKF 23148 CC/C3W33 self-aligning roller bearing withstands heavy loads and automatically compensates for misalignment between the shaft and housing. As an open roller bearing with main dimensions of 240 mm bore, 400 mm outer diameter and 128 mm width, this model is designed for installation in enclosed housing systems. The integrated sheet steel cage guides the rolling elements through the raceways with minimal vibration.

What is the 23148 CC/C3W33 self-aligning roller bearing suitable for?

Design engineers and maintenance technicians rely on this bearing when heavy shaft mountings need to rotate reliably despite deflection or assembly inaccuracies. The hollow-spherical outer ring raceway allows angular movements without impairing function. Typical applications include industrial settings where high radial forces and axial forces acting on both sides occur, and where misalignments need to be compensated for.

What do the C3 clearance and the designation W33 mean for this bearing?

The suffix C3 indicates an increased radial clearance as supplied. This additional freedom of movement prevents the rolling elements from becoming stressed when the shaft and bearing rings heat up during operation or when tight fits cause the inner ring to expand. The designation W33 stands for a circumferential lubrication groove with lubrication holes in the outer ring. Maintenance teams use this to feed the lubricant directly between the roller sets, which facilitates relubrication whilst the bearing is in operation.
