XV

The XV type is designed with mounting holes in the outer ring and splited inner ring, since it has mounting holes on the outer ring, flanges and housing are not required when installing. In addition, because of the integrated outer ring, the installation has almost no effect on performance, so stable rotation accuracy, torque and rigidity can be obtained, it is mostly used in applications where the outer ring rotates, such as industrial robot joints, special robots, CNC multi-axis turntables, and rotating Tool magazine, industrial turntable, counterpoint platform, radar communication equipment, etc.
