Complex Centrifugal Replaces Fabrication
Controllable pitch propulsion systems provide the ability to alter the angle of a ship’s propeller while in use, allowing for different performance during cruising and maneuvering. A centrifugal hub provides the strength and size needed to transfer horsepower to the attached propeller blades, and must perform in corrosive environments for the life of the vessel. Fabrications previously used were very intricate, with multiple pieces and welds, and much machining. The single piece nickel aluminum bronze hub that MetalTek supplies eliminates welded joints and fabrication defects that are only discovered after finished machining.
