Features:
Size: Outer diameter X length: D7.4mm x L23.7mm, connection aperture: 4mm to 4mm.
Made of high-quality aluminum alloy, with high torque rigidity, low inertia and good sensitivity, wear and corrosion resistant.
Advantages: metal material, same outer diameter length, can be used directly instead of plastic coupling, more durable.
It connects two shafts to transmit power and torque, and play a protective role when the load is too large.
Warm reminder: Rigid type basically does not allow eccentricity, and must be fully adjusted during use.
