What makes the Bruntons Sigmadrive Coupling different is its ability to resist propeller thrust when installed as a standalone coupling, directly from the shaft to the output flange on the engine’s transmission. It reduces and even eliminates vibrations that originate from an imperfect alignment between the propeller shaft and the engine, compensating for up to 3 degrees in all directions. This system can also be installed using thrust bearings so that the engine can be placed utilizing the space available ergonomically.

 

Manufactured from a special Aluminium Bronze, SigmaDrives are a premium product requiring virtually no maintenance and containing no bearings or rubber in their construction. In addition to requiring little maintenance themselves, fitting one also means considerably reduced maintenance will be necessary on other stern gear components.

  • Compact size, comparable to a standard shaft coupling.
  • Provides perfect alignment for the propeller shaft and works perfectly in line or out.
  • Easy and quick to fit, usually without slipping the vessel and without the need to modify the propeller shaft, or fit fixture plates or brackets for thrust bearings that are no longer required.
  • Contains no rubber or bearings, and is manufactured from a special alloy that ensures long life with little maintenance required.
  • A highly cost-effective solution requiring little or no costly modifications to the vessel.
