Slewing ring bearings consist of an inner ring and an outer ring, one of which typically contains a gear. Together with the connecting holes in the two rings, they enable optimized power transmission and simple and fast connection between adjacent machine components. The bearing's raceways and rolling elements (as well as the cage or spacers) work together to accommodate unidirectional loads or combined loads in any direction.

JOJI manufactures a wide range of standard and custom support slewing bearings with outside diameters from 0.1 to 18 mm to meet the needs of special applications.
