AB/ABR Helical Servo Gearbox

AB series and ABR series (angle version) built with precision helical gears. The gears shape optimized by 3D Simulation technology. Single piece structured ring gear to minimize the assembling error accumulation. Whole piece planetary carrier with bearings supported on each end taken large radial load capacity. They are best choice for the precision positioning applications as well as smooth running required.
