**For loads of 25% to 100% of actuator capacity, torque requirements are approx. proportional to the load.

Options (Dimensions Subject to Change)
Inverted Rotating Screw: Contact Sales for details.
Anti-Backlash Option: Reduces vertical backlash between the screw and the worm gear nut to a practical minimum for smooth, precise operation and minimum wear.
Keyed: Stops a translating screw from rotating when the screw ends are free.
Secondary Guide: Increases lifting screw lateral rigidity aiding screw guidance and improve side load resilience.
Bellows Boot: Protects the screw from dust, dirt, moisture and corrosive contaminants.
Ballscrew Version: Higher cycles.
