Machine Screwjack Actuator, 100t to 250t

Screwjack Actuator.

Model:

MSAT-4049

Machine Screwjack Actuators

These screw actuators offer 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 accurately 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.

* For loads of from 25% to 100% of Actuator load rating. Torque requirements are approximately proportional to the load.

** Closed heights are for standard upright top plate models and may vary with different screw ends, inverted models, or when bellows boot is used.
