Linipower Jack JWM (Trapezoidal screw type )
- JWM (trapezoidal screw type) is a general-purpose, low-noise electric jack.
- Main components include an aligning trapezoidal screw and a high-precision worm gear.
- Simple and compact structure makes this type economical. Load retention is possible (self-locking feature).
- Left-handed screw and stainless steel screw specifications are also available..
Features
-
・Economical
Simple and compact structure makes this type economical.
-
・Low Noise
Ideal for low-noise applications due to sliding contact of the trapezoidal screw.
-
・Holds heavy loads
The trapezoidal screw thread has a self-locking feature in terms of calculation and load retention is possible.
※In situations where the self-locking function will not work due to vibration and shock. a brake unit is required.
-
・Trapezoidal screw type Stainless screw specifications
For two models, JWM025 and JWM050, the austenitic stainless steel made screw shafts are available.
Ideal for equipment requiring rust prevention on screw shafts, water gates and various gate openings/closures, environmental equipment, paper making machines, etc.
-
・Trapezoidal screw type Left hand type
The left hand type has same input direction of rotation, but moves in a direction opposite of the right hand type. When using multiple jacks driven by one motor, or due to jack installation, the left hand type can operate problem free even if the input direction of rotation is different.
