Rockford Ball Screw products provide our customers the ability to lift, position, hold and support loads in a variety of industrial applications. We support Marine applications by supplying robust standard ball screws and free wheeling units with short lead times and competitive pricing. In addition, we store our customer's product (Kanban systems) for rapid turnaround times.
Automatic hatch lifts are becoming extremely popular in the marine industry. The first illustration (1) to the shows RBS screws automating a boat "trunk storage" hatch lift.
While we supply actuation for all hatch lifts, one of the areas our product automates is the hatch lift for the engine. This raises and holds the motor cover, generating a spacious area for the boat owner to safely maintain the boat motor systems.
Another marine application Rockford Ball Screw supplies product to is TRIM TABS. RBS is a top supplier in this area. Trim tabs allow for smooth sailing when the water is choppy. The ball screws for trim tabs shown below are supplied to some of our best customers for Marine products (Lenco, Bennett Marine, Linear Devices, etc.).
We do this by utilizing a free-wheeling ball screw. The screw is actuated by a small motor with a gear box reducer. The ball nut on this device can travel the length of the screw, stop at the desired, full forward or full reverse, position and stay there while the screw is still turning. This eliminates electrical stop switches.
