1/4 to 350 ton capacity.

Acme screw jacks offer positive mechanical action, precise positioning, and uniform lifting speeds. Standard configurations include upright or inverted units with translating or rotating lifting screws, and top plate, threaded, or clevis ends.

FEATURES & BENEFITS

Machine Screw Actuators 1/4 ton to 350 ton
PRECISE POSITIONING
Machine Screw Actuators can be controlled accurately for positioning within thousandths of one inch.

SELF LOCKING
Models featuring higher gear ratios are inherently load holding as long as the actuator is not subject to vibration

UNIFORM LIFTING SPEEDS
Since many actuators feature the same gear ratios different capacities can be used in the same application to lift unevenly distributed loads with uniform speeds.

QUICK, SURE OPERATION
All actuators are designed and built to be positive acting, for accurate response to motive power.
