A new generation of Wärtsilä hydraulic couplings to provide solutions where it was previously impossible to maximize propulsion efficiency without shaft connection complexity. This innovative technology reduces surface contact pressure while increasing torque transmission capacity by 30% offering substantial cost-savings in the shaft line.
The couplings avoid the use of costly reinforcement sleeves, as well as the need to substitute large connection couplings. Designed for an easy, clean and fast install/uninstall with minimal personnel. Re-engineered to be 30% lighter, they are available in a wide range of sizes to ensure the perfect fit for your vessel.
