Straight Gear Reducer
The straight gear reducer features a precision planetary gear train with coaxial input and output shafts, offering compact size and high torque output. Utilizing straight-cut (spur) gears, it delivers efficient power transmission with robust mechanical simplicity. Gears are carburized and quenched under a controlled atmosphere to achieve a tooth surface hardness of HRC58–62, while the high-strength ductile iron housing provides excellent resistance to wear and impact. With a single-stage efficiency of ≥97%, and configurable in 1–3 stages, the reducer offers a wide transmission ratio range from 3 to 250. A return clearance of ≤10 arc minutes ensures reliable positioning accuracy in cost-sensitive or high-volume automation systems.

Engineered To Perform Across Industries
