The SWL screw jack is a versatile and reliable linear motion solution designed for industrial lifting, lowering, pushing, and positioning tasks. As a fundamental mechanical screw jack actuator, it is widely used in machinery manufacturing, automation, construction equipment, stage systems, and material handling applications. With a compact structure, long service life, and strong load capacity, the SWL series provides a stable and cost-effective alternative to hydraulic and pneumatic lift systems.
The SWL series is built around a worm gear and trapezoidal screw mechanism, offering excellent self-locking performance, smooth operation, and precise height control. It can be powered by electric motors or operated manually, supporting a wide range of lifting requirements. Available in multiple configurations and installation forms, the SWL screw jack can be used as a single unit or combined into multi-jack lifting systems for synchronized motion.
Key Features
Compact & High-Strength Structure: The SWL worm screw jack features a compact body, light weight, and high structural rigidity. The worm gear mechanism ensures stable torque transmission and long service life even in continuous operation.
Versatile Operation Methods: Electric motor drive; Handwheel / manual operation; Servo motor or stepper motor compatible. This flexibility makes it suitable for both manual screw jack and electric screw jack actuator applications.
Accurate Lifting & Positioning: The internal worm gear lifting system allows precise linear motion, making it ideal for environments requiring controlled lifting, lowering, or pushing. SWL jacks can be arranged in single, dual, or multi-unit combinations for synchronized motion.
Multiple Structure & Assembly Options: Available in various structural types to support different engineering needs: *Translating screw type *Rotating screw type *Anti-rotation version *Upright or inverted installation *Customizable lifting height This makes the SWL series suitable as a machine screw jack in a wide range of industries.
Quiet, Smooth, and Safe Operation: The worm gear mechanism ensures: *Low noise *Smooth travel *High reliability *Natural self-locking ability (safety holding force when power is off)
Whether used as a worm screw lift, mechanical screw jack, or a synchronized multi-jack actuator system, the SWL series provides stable and reliable performance. Learn more about the working principles of screw jacks on Wikipedia.
