Spherical roller bearings on an adapter sleeve

Spherical roller bearings have two rows of rollers with a common sphered raceway in the outer ring and two inner ring raceways inclined at an angle to the bearing axis.

This gives them an attractive combination of design features making them irreplaceable in many demanding applications. They are self-aligning and consequently insensitive to misalignment of the shaft relative to the housing and to shaft deflection or bending.

Spherical roller bearings are leading in design and can, in addition to high radial loads, accommodate high axial loads acting in both directions.

The standard range of spherical roller bearings comprises

-Open bearings

-Sealed bearings

-Bearings for vibratory applications.

In addition to the standard range, offers a wide range of special spherical roller bearings adapted for specific applications.
