Water-resistant lead screws & nuts for boat lifts, docks and interiors

Boat lifts are one of the most important applications for lead screws, as a high load capacity is essential to be able to withstand the weight of the boat. Other applications include various moving components on the interior of a boat such as windows, adjustable television stands and seating adjustments.

dryspin® lead screws and nuts are ideal for these applications, as the high-performance polymers used in the nuts have a high weight capacity, low moisture absorption, and maintain good wear resistance in submerged applications.

The lead screws are available in both 304 and 316 stainless steel, so whether your application is used in freshwater or saltwater performance won’t be negatively impacted. Various IP-rated motors are also available to pair with our lead screws, creating an entire system with adequate water resistance.

Racing Sailboat

A racing sailing boat that hovers over the water surface thanks to special wing profiles and the conversion of water pressure.

The students of the Polytechnic of Turin build racing sailboats with airfoils. The pressure exerted by the water on the profiles causes the boats to hover, reducing hull friction and allowing full use of the wind's propulsive power. One of the systems developed is the rudder mount. It allows sailors to adjust the angle of attack of the profile at the rudder end, instantly providing the desired lift for the racing conditions at hand.
