ZCH-120 Hypoid Gear Hollow Rotary Table
The ZCH-120 hypoid gear hollow rotary table is a medium-size right-angle rotary platform for automation systems requiring higher load capacity, compact motor installation, and stable hollow output rotation. Compared with ZCH-60, it provides stronger axial and radial load support for assembly fixtures, inspection modules, and compact indexing equipment.
