Worm Gear Screw Jack
Worm gear screw jacks are a core category of screw jacks, utilizing a worm gear transmission mechanism as the core driving unit. Combined with a screw and nut assembly, they convert the rotational motion from a motor or manual input into precise linear lifting motion, making them a commonly used linear actuator in industrial applications.

Features
- Self-locking: Most models have self-locking capabilities, eliminating the need for additional braking when the load stops, ensuring high safety;
- Reduce speed and increase torque: The worm gear drive has a large reduction ratio, allowing for the output of high thrust (up to several hundred tons per unit);
- Controllable precision: Slow lifting speed and high positioning accuracy make it suitable for applications requiring precise adjustment;
- Compact structure: High integration, small installation space, and supports synchronous linkage of multiple units.
