Slewing bearings

SKF
Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear.
Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components.

The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.
We can provide you standard and customized slewing bearings in various designs, with outside diameters from 0,1 to 18 m to meet the demands of particular applications.

Further to that, we can provide you as well Standard or custom-made slewing bearings from other wellknown manufacturers which are only specilized in this field. Please contact us for further information.
