Spherical Roller Bearings SKF 23030 CCK/W33

The SKF 23030 CCK/W33 spherical roller bearing compensates for misalignment and, with dimensions of 150 × 225 × 56 mm, withstands high radial loads in industrial applications.

The 23030 CCK/W33 self-aligning roller bearing is a double-row roller bearing designed for demanding mechanical environments. This SKF model combines a tapered bore with an integrated lubrication groove and lubrication holes in the outer ring. As it is designed as an open bearing, lubricant reaches the moving parts directly. A sheet steel cage guides the rolling elements in an orderly manner between the inner and outer rings. This ensures the component maintains smooth running characteristics under varying mechanical loads.

In which installation situations does the 23030 CCK/W33 self-aligning roller bearing compensate for misalignment?

This rolling bearing proves particularly effective under high radial loads and demanding operating conditions. Wherever shaft deflection occurs or misalignment between bearing positions needs to be compensated for, the spherical outer ring raceway demonstrates its advantages. The bearing compensates for angular misalignment without any significant increase in friction. As it is suitable for a temperature range of –30 to +200 degrees, the component can withstand thermal operating conditions in continuous operation.

What is the function of the tapered bore and the W33 lubrication groove?

The designation ‘K’ indicates the tapered inner bore with a taper ratio of 1:12. This design facilitates assembly, as the bearing can be mounted either directly onto a tapered shaft seat or using a mounting or withdrawal sleeve. The suffix W33 indicates the circumferential groove with lubrication holes in the outer ring. This allows fresh grease or lubricating oil to be fed directly into the bearing, which simplifies routine maintenance.
