Midwest Motion Products (Howard Lake, MN) offers the Model MMP LA3-12V-5-A-SP- 100 linear actuator that utilizes an all-steel drive pinion while maintaining a 5:1 reduction ratio that allows the unit to maintain a 2"- per-second stroke speed. The stroke length for the design is 4" overall, but the same design is available with 2, 6, 8, 10, and 12" stroke lengths. The actuator features 8-mm-diameter clevis mounts on both ends, and built-in limit switches for both (full extend and full retract) ends of travel. The operating temperature rating range is from –26 °C to +65 °C. An acme screw drive allows for 517 pounds of static load.
