Yaskawa ES165D, ES165DX T-Axis Speed Reducer

The Yaskawa 156809-1 Speed Reducer is a highly robust mechanical power transmission unit specifically engineered for the T-axis of heavy-duty industrial manipulators. Its primary function is to step down the rapid output from the driving servo motor and convert it into the high-torque, controlled motion necessary to rotate the robot's end-effector safely and accurately. This speed reducer is heavily deployed in large-scale automated multi-angle dispensing, where continuous and dynamic wrist twisting motions are required. Key features of this component include a rugged internal gearing architecture that guarantees exceptional torsional stiffness and virtually eliminates backlash, providing consistent, pinpoint accuracy during aggressive rotational cycles under heavy payloads. Furthermore, its compact design ensures it fits perfectly within the robot's wrist casting without adding unnecessary bulk. Regarding compatibility, the 156809-1 is tailored to seamlessly integrate with designated high-capacity Yaskawa Motoman ES165D and ES165DX robot manipulators.
