💡 What is a universal joint shaft coupler used for in motion systems? A universal joint shaft coupler joins two rods that sit at an angle so power moves through the bend without binding. It works well in rc airplanes boats and robot arms where the motor and driven part are not in a straight line. The rotatable design lets builders tweak the angle quickly during setup or repairs. Metal construction keeps the link strong while the 128g weight stays light enough for hobby projects.
