Spherical Roller Bearings SKF 23126 CC/W33

The SKF 23126 CC/W33 self-aligning roller bearing combines dimensions of 130 × 210 × 64 mm with enhanced P5 running accuracy for demanding industrial applications.

The 23126 CC/W33 self-aligning roller bearing accommodates high radial loads as well as axial loads on both sides simultaneously. The open bearing design, made from 100Cr6 rolling bearing steel, covers a temperature range from –30 to +200 degrees. Thanks to the hollow-spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation. The integrated sheet steel cage guides the rolling elements precisely and withstands mechanical stresses.

What loads can the 23126 CC/W33 self-aligning roller bearing accommodate?

The design is intended for high loads whilst accommodating housing deformations or misalignments. The spherical geometry of the raceway helps to reduce undesirable edge stresses on the rollers. The standard radial clearance is optimised for normal operating temperatures and standard fits. Thanks to its open design, the bearing can be incorporated into housing designs with an external lubrication supply.

What are the advantages of the W33 designation and the P5 running accuracy?

The suffix W33 denotes a circumferential lubrication groove with lubrication holes directly in the outer ring. This design directs grease or lubricating oil directly between the rows of rollers and simplifies regular maintenance of the bearing location. Whilst the dimensional accuracy corresponds to class PN, the bearing operates with the restricted running accuracy P5. This combination ensures low-vibration concentricity on shafts with increased requirements for guidance accuracy.
