Buck Algonquin Shaft Coupling 50-9001U

9" Buck Algonquin Split Propeller Shaft Coupling for Allison, and Twin Disc Marine Transmissions.

The 9" Buck Algonquin Split Propeller Shaft Coupling is engineered for Allison and Twin Disc marine transmissions, providing a secure and precise connection between the transmission output flange and propeller shaft. Designed for demanding inboard applications, this coupling ensures consistent power transfer and alignment under load.

Its split coupling design allows for easier installation and removal compared to traditional solid couplings, eliminating the need for extensive shaft disassembly during maintenance or replacement. This significantly reduces service time while maintaining a tight, reliable fit.

Constructed from high-strength ductile iron and machined to strict marine tolerances, the 50-9001U ensures reliable power transfer, proper shaft alignment, and long service life in demanding inboard applications.
