SKF 23060 CCK/W33, Double-row spherical roller bearing, 300 mm ID, 460 mm OD, Sheet metal Cage

Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.

The assortment of standard bearings includes basic design bearings, sealed bearings, bearings for vibratory applications.

Spherical roller bearings without seals
Open spherical roller bearings are available with either a cylindrical or tapered bore to suit all mounting methods. Depending on the bearing series, the tapered bore has a taper of either 1:12 (designation suffix K) or 1:30 (designation suffix K30). To facilitate efficient lubrication, most bearings are provided with an annular groove and three lubrication holes in the outer ring.
