The Navtec ultra-light, custom 7500 psi M Cylinder delivers maximum muscle where it is needed most on the world’s top racing yachts. The standard on TP52s, IRC designs, and high-performance race yachts, the M Cylinder has helped drive America’s Cup class winners since 1992.
By designing a cylinder that operates at 7500 psi rather than the standard 5000 psi or the heavier 10,000 psi, Navtec have improved the hydraulic working performance. Higher pressure results in faster performance alongside a reduction in size and weight. Machined from one long bar with an integral cylinder end fitting, weight has been reduced by eliminating the need for a mechanical end fitting. Eliminating the need for seals at the cylinder end has reduced the overall length. Machining the cylinder from a solid bar means that an unlimited number of end fittings can be incorporated, including clevis, jaw, eye, lashing eye, and threaded.
For the America’s Cup yachts, the Navtec cylinder is machined from a high-strength 7000 series aluminum material, while a more marine stable 6000 series aluminum is used for grand prix race yachts where longer life span is required. While the 6000 series aluminum increases the weight of the cylinder by approximately 6%, the life span increases from 2-3 years to 6-8 years without compromising on performance.
The M Series Cylinder integrates with the Navtec 7500 psi Valve, providing a sophisticated hydraulic system that delivers the highest level of performance.
