Tsubaki LiniPower® Jack JWM (Trapezoidal Screw Thread Type)
Main components include an aligning trapezoidal screw and a high-precision worm gear.
Features
Economical
Simple and compact structure makes this type economical.
Low-Speed, Low-Frequency
Ideal for low-speed, low-frequency applications due to sliding contact of the trapezoidal screw.
Load-holding
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.
Left hand type trapezoidal screw Lini Power Jacks
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.
