Spherical Roller Bearings SKF 23026 CC/W33

The SKF 23026 CC/W33 self-aligning roller bearing (130x200x52 mm) withstands heavy radial loads and compensates for misalignment of the rotating shaft.

The 23026 CC/W33 self-aligning roller bearing is a rolling bearing made from standard bearing steel (100Cr6) for demanding industrial applications. The barrel-shaped rollers run on a common hollow spherical outer ring raceway, enabling the bearing to adapt to misalignments through angular movement. SKF manufactures this design in the Explorer performance class with standard radial clearance. The open bearing has a bore of 130 mm, an outer diameter of 200 mm and a width of 52 mm.

What is the 23026 CC/W33 self-aligning roller bearing suitable for in operation?

This rolling bearing is suitable for designs where high loads occur and elastic shaft deflection is to be expected. With larger bearing spacings, alignment errors between the housing seats may occur due to installation. The self-aligning roller bearing compensates for these misalignments during operation without causing adverse edge pressure. The design simultaneously accommodates high radial forces and axial forces acting on both sides, thereby relieving mechanical stress on adjacent components.

What do the designations CC, W33 and P5 mean in terms of bearing selection?

The abbreviation CC describes inner rings without a guide ring, featuring symmetrical rollers and window-type sheet steel cages that reduce friction. W33 denotes a circumferential lubrication groove with lubrication holes in the outer ring, which simplifies targeted relubrication. The tolerance class combines standard dimensional accuracy (PN) with enhanced P5 running accuracy for smooth concentricity. When selecting a lubricant, the permissible temperature range of -30 to +200 degrees must also be taken into account.
