  • Quick, Sure Operation
    Duff-Norton metric machine screw actuators offer positive mechanical action, precise positioning, and uniform lifting speeds.
  • 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.
  • ISO Recommended Standards
    Metric shaft and keyway sizes per ISO recommended standards
