Tyre couplings Y Simple structure, excellent misalignment
compensation and vibration dampening
capability, yet require ample radial space;
Suitable for frequent start/stop cycles,
reversing torque loads, heavy shock,
vibration applications.

Metallic grid Y Good misalignment compensation
With metallic elastic elements Suitable for shock loading, medium to high
couplings capability, complicated structure, require
lubrication;
power transmission.

Diaphragm
lightweight;
couplings √ √ √ Y Simple structure, no need for lubrication,
Suitable for high-speed, high-temperature
or high-performance applications, like gas
turbines, precision machines, servo
systems.
