Universal Couplings (Set Of 4) (83290)

Universal Joints Transmit Power, Isolate Vibration

Universal Coupling Set transmits smooth power between angled drive shafts in boats, trains, autos and other model mechanisms. Robust nylon ball-and-socket joints and 3/32 inch square brass drive rod transmit power at shaft angles up to 45 degrees. Sliding-ball technology compensates for the normal change in distance between the ends of the shafts as they change position. Set includes enough components to assemble 4 complete heavy-duty universal couplings up to 3-1/8 inches long. Overall diameter is 9/32 inch. Sockets press fit on 3/32 inch diameter shafts, but other shaft sizes can be used by bushing or boring out the socket.
