Yaskawa EPH130 JT2-Axis Speed Reducer

The Yaskawa 167939-1 Speed Reducer, designed as model EPH130 for the JT2-axis is an indispensable mechanical element designed to control the primary lifting arm of heavy-duty industrial robots. Its core purpose is to step down the high RPM output from the driving servo motor and convert it into the immense torque necessary to elevate and maneuver the robot’s lower arm against gravity, especially when carrying maximum payloads. The application of this specialized reducer is critical in demanding industrial processes such as heavy part transfer. Key features include an advanced cycloidal or planetary gear design that provides exceptional shock load resistance, high kinematic accuracy with near-zero backlash and superior rigidity. These features ensure that the robot maintains strict path accuracy during aggressive vertial movements. In terms of compatibility, the 167939-1 is precision-matched for specific high-payload Yaskawa Motoman robot manipulators.
