Yaskawa 26H002-20 RV Reducer Gearbox Assembly

The Yaskawa HW9280632 (26H002-20) RV reducer gearbox assembly delivers high-torque, precise L-axis and U-axis motion for Motoman SK6 robot systems. As an RV speed reducer, it reduces speed and increases torque to the joint drive, supporting smooth, repeatable positioning in robotic welding cells, material handling lines, and automated production environments where cycle time and accuracy are critical. The unit features a precision-machined gearbox housing designed for integration into the robot arm joint and typically weighs about 9.5 to 15 pounds depending on configuration; it is a discontinued Yaskawa part that is commonly available refurbished or surplus. Common replacements include Yaskawa HW9280631, HW9380957, and HW9380942.
