Screw Jack

A screw jack is a mechanical transmission device that converts rotary motion into linear lifting motion. Its core function is to achieve precise lifting, pushing, pulling, or positioning of heavy objects, and it features both high load-bearing capacity and high control precision.

• Self-locking: This is one of its most significant advantages. Due to the typical use of worm gear drives, when the reduction ratio is large enough, friction creates a self-locking effect. This means that when power is off or the drive stops, the load can safely remain in any position without falling, eliminating the need for additional braking devices.
• High-precision positioning: The helical drive itself has high displacement accuracy, enabling precise stroke control.
• High thrust: A large axial thrust can be generated with a small input torque.
• Compact structure and flexible installation: Diverse designs allow for easy installation in various directions (push-up, pull-down, horizontal push, etc.).
• Simple maintenance and long service life: Reliable structure, with proper selection and lubrication, results in a long service life.
