[Total Size] - Outer Diameter: 12mm / 0.47".
Connection Diameter: 4mm to 4mm / 0.16" to 0.16".
[Material] - This universal coupling is made of premium iron metal material, which is durable and has a long service life, fine workmanship.
[Feature] - The universal joint of the purpose is to firmly connect the driving shaft and the driven shaft to rotate together and transmit motion and torque, cost effective coupling design, which is very flexible and easy for use, and is great replacement for your old or broken one.
[Design] - Rotatable design. Allow the angle between the two axes within a limited range vary with operational needs, and easy to set up the items on the shaft and control the holding capacity of the coupling.
[Wide Application] - Universal joint coupling are used in servo motor systems, 3D printer, cnc machine, diy encoder, spindle transmissions, stepping motors, lifting platforms, machine tool transmissions, stepping motors, encoders, screw drives, machine platforms or gearboxes, etc.
Great suitable for short support shaft, bushing model, miniature Shaft, model airplane/ boat/ car.
