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.
