Linipower Jack JWM (Trapezoidal Screw Type)

- JWM (Trapezoidal Screw type) is a general-purpose, low-noise screw jack.
- The main components are a concentric Trapezoidal Screw and a high-precision worm gear.
- Simple, compact structure and economical. Load retention is expected. (Self-locking)
- Left-handed and stainless steel screw specifications are also available.
Features
-
Economical
Its simple and compact structure makes it economical.
-
・Low noise
It uses Trapezoidal Screw with sliding contact, making it ideal for applications where noise is a problem.
-
・Load retention
Trapezoidal Screw are calculated to have self-locking properties, and can be expected to retain load.
*The self-locking mechanism may become ineffective due to vibration, shock, etc. In such cases, a brake device is required.
-
-Trapezoidal Screw type, stainless steel screw specifications
For the two models JWM025 and JWM050, austenitic stainless steel screw shafts are now available.
Ideal for devices that require rust prevention on screw shafts, water gates and various gate opening and closing devices, environmental equipment, paper manufacturing machines, etc.
-
-Trapezoidal Screw type, left-hand screw specification
The input rotation direction is the same, but the screw moves in the opposite direction to the right-hand screw specification. When using multiple jacks driven by one motor, or when the input rotation direction is not the same due to the installation of the jacks
However, this can be easily solved if there is a left-handed thread specification.
