The function of a coupling is to connect two shafts (active and driven) in different mechanisms to rotate together and transmit torque. Some couplings also have functions such as buffering, vibration reduction, and improving the dynamic performance of the shaft system.
Capable of simultaneously absorbing large deflections, eccentricities, and axial movements
Fully absorb shock/vibration/no lubrication/low inertia torque/with electrical insulation
