    Couplings

    Duff Norton provides three types of couplings which have been specifically matched for ease of installation to actuators.

    Jaw Couplings

    – Integrate well with Duff-Norton smaller capacity actuators
    – Do not require lubrication
    – Our Hytrel(registered) spiders provide 2x the torque capability vs. a standard urethane or BUNA(registered) spider
    – Easy fit onto the actuators worm shaft

    Chain Couplings

    – Integrate well with Duff-Norton mid and larger capacity actuators
    – High torque capacities
    – Standard ANSI dimensions, straight bore diameters
    – Common bore diameters readily available
    – Special bore diameters may be custom ordered
    – Long service life
    – Easy fit onto the actuator’s worm shaft
    – Allows for incremental system adjustments

     

    Gear Couplings

    – Give great strength under load due to compact design and construction.
    – Allow for incremental system adjustment.
    – Long service life
    – High torque capacities
