Description for Machine Screw Actuators 1/4 Ton to 250 Ton
Duff-Norton offers a complete line of both standard and custom engineered machine screw actuators for applications up to 250 tons.
- Precise Positioning - 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
