ZH Flexible Propeller Shaft Coupling



Manufactured from a special bronze alloy, ZH COUPLING require virtually no maintenance and containing no bearings or rubber in their construction. The knock on effect of using a ZH COUPLING shaft coupling is that the forces typically generated from misalignment will not be transferred to the engine or transmission  extending their life significantly.

Unlike existing shaft couplings ZH COUPLING does not use rubber to dampen the vibrations or take out misalignment. ZH COUPLING shaft couplings are special constant velocity joints that are able to resist the propeller thrust without the need for thrust bearings in most applications. They are extremely compact and able to transmit higher torque than other propeller shaft couplings with similar dimensions. In addition, as they do not use rubber as a vibration suppression device, they are an exceptionally long wearing marine coupling, with minimal maintenance needed.
