    Acme screw jacks for industrial applications
    An Acme screw jack with a traveling nut (or rotating screw) operates by having the lifting screw rotate within the gearbox, causing a guided nut to travel up and down the screw to move a load, rather than the screw translating itself. It is ideal for horizontal movement, compact spaces, or when the screw cannot protrude through the floor. 
    Key Features and Benefits 
    • Mechanism: The screw is keyed to the internal worm gear, forcing it to rotate while the external nut moves linearly.
    • Applications: Commonly used in industrial automation, material handling, and systems requiring synchronized, precise lifting or pushing.
    • Self-Locking: Acme screws are generally self-locking, meaning they hold the load in position without a brake when the screw efficiency is below 35%.
    • Versatility: These jacks can be operated manually or via motors, handling capacities ranging from 1 ton to over 100 tons.
    • Configurations: Available in upright (standard) or inverted (downward-facing) orientations. 
    Commonly Available Options 
    • Manufacturers: Offered by companies such as Joyce Dayton, Nook Industries (ActionJac), Servomech, and Lude Transmission.
    • Materials: Typically use high-strength bronze for the worm gear and traveling nut to reduce friction, with stainless steel options available for corrosive environments.
    • Customization: Custom travel lengths, screw diameters, and multi-start screw options (1, 2, 3, or 4 starts) are available from manufacturers like Lude Transmission. 
    These systems are ideal for applications requiring consistent, reliable, and often self-locking linear motion.
