The DCS(G) Series is a compact harmonic reducer designed for robotic and automation applications requiring precise positioning and reliable transmission performance. Its optimized structure integrates high rigidity, low hysteresis characteristics, and accurate motion control capabilities into a compact form factor. With transmission accuracy reaching 30 arcsec and hysteresis loss controlled to 1 arcmin, the series supports robot joints, automated mechanisms, and precision motion systems requiring stable and repeatable operation.
Optimized tooth engagement improves transmission accuracy and reduces positioning deviation in robotic motion systems.
Reinforced mechanical structure provides stable T1/T2 stiffness for dynamic loads and precise movement control.
Space-efficient design enables easy installation in robot joints and automated equipment with limited mounting space.
The DCS(G) Series covers sizes 14, 17, 20, 25, 32, 40, and 45, with reduction ratios from 50 to 160. Specifications include transmission accuracy, hysteresis loss, and torsional stiffness parameters.
