Yaskawa Motoman HW9381465-A Planetary Gear Reducer

The Yaskawa Motoman HW9381465-A Planetary Gear Speed Reducer delivers precise torque multiplication and speed reduction for the UP130 robot manipulator’s L-U axis, enabling accurate, repeatable axis motion in high-precision manufacturing. As part of the RV/planetary reducer family in the 320E reducer class, it provides approximately 171:1 reduction and mounts with an integrated mounting position within the robot axis assembly for compact, reliable drive performance. This reducer is used across industrial robot arms, welding robots, material handling systems, and automated production cells to amplify torque while preserving controlled motion for articulated axes. Manufactured in Japan by Yaskawa Motoman, the HW9381465-A carries the manufacturer part number HW9381465-A and is available in new, surplus, or used condition to support maintenance, retrofits, or replacements for UP130 configurations.
