Screwjack Actuator
Model:
MSAT-4046
Machine Screw Jacks
These screw actuators offfer a positive mechanical action, precise positioning and uniform lifting speeds.
The standard configurations include, upright or inverted units with translating or rotating lifting screws, with top plates, threaded or clevis end fittings.
They can be controlled accuratley for positioning within thousands of one inch.
Unevenly distributed loads can be lifted with uniform speeds.
All actuators are designed and built to be positive acting, giving accurate response to motive power.

These screw actuators offfer a positive mechanical action, precise positioning and uniform lifting speeds.
The standard configurations include, upright or inverted units with translating or rotating lifting screws, with top plates, threaded or clevis end fittings.
They can be controlled accuratley for positioning within thousands of one inch.
Unevenly distributed loads can be lifted with uniform speeds.
All actuators are designed and built to be positive acting, giving accurate response to motive power.
