What Is a JWM Trapezoidal Screw Jack?
The JWM trapezoidal screw jack is a mechanical linear actuator that converts rotary motion into linear motion for lifting, lowering, pushing, and positioning heavy loads
It consists of two main components:
A precision trapezoidal screw (the threaded rod that moves up and down)
A high-precision worm gear (the mechanism that drives the screw)
The Name Explained
| Part | Meaning |
|---|---|
| J | Japan-origin design standard-1 |
| W | Worm gear screw jack |
| M | Machine screw type (trapezoidal thread) |
Low speed, low frequency operation
Heavy loads with infrequent movement
Cost-effective applications
Where Are They Used?
JWM screw jacks are widely used in mechanical equipment, water conservancy, metallurgy, construction, and industrial automation
