Benefits of Worm Screw Jack:
Self-locking safety
Holds the load securely in position without the need for continuous power — preventing accidental lowering.
Precise motion control
Ensures accurate linear movement, ideal for automated systems requiring high positioning accuracy.
High load capacity
Capable of handling multi-ton loads in presses, platforms, and machinery setups.
Compact & modular design
Small in size yet powerful, making them easy to install in tight or modular systems.
Low maintenance
No hydraulic leaks or complex oil systems — only periodic lubrication and inspection needed.
Versatile drive options
Can be manually operated, motor-driven, or integrated into synchronized systems for multi-point lifting.

Types of Worm Screw Jack:
Parallel shaft worm gear screw jack
This type of screw jack is distinguished by the worm and screw, which run parallel to each other. They are integrated into the same mechanical system. When engaging, the worm turns the screw to create the required linear motion. This effort results in an effective space-saving design and can elevate significant loads.
Translating screw jack
Translating screw jacks are engineered to move the load by causing the screw to drive through the nut fixed on the frame. These jacks provide direct linear motion, making them suitable for applications requiring precise position adjustments.
Ball screw jack
A ball screw jack incorporates a ball screw. It utilizes ball bearings to minimize friction between the screw and nut, thus enhancing efficiency. This capability also results in a greater load-carrying capacity and longer service life. These features make this jack ideal for high-performance scenarios.
Nutnecked screw jack
A floating screw jack nut is characterized by its nut that moves along the screw threads to translate the worm's rotational motion into linear motion. This kind of screw jack is highly valued for its ability to effect changes with low friction and high efficiency. Often, this screw jack type is found in spaces critical for application in movement with less required space.
Bevel worm gear screw jack
An angle skew bevel cone worm gear screw jack includes a bevel worm and screw engagement at certain angles. This configuration allows for more compact designs with the ability to change directions and high load capacities. These are preferable in areas requiring vertical or horizontal load support and transfer.
