Use our configurator to build the right part for your application.
    The Hydraulic Unibody (HUB) series actuator is designed to perform in the harshest environmental conditions. Built with a hard-coat anodized housing and hardened, high-strength alloy steel pinion and racks, this product is ideal for applications where weather can be a factor. The HUB series is designed with several add-on valve modules for lower overall integration costs, as well as an increase in product performance. Multiple feedback and visual indication options are also available.

     • Output torques @ 3000 psi (207 Bar): 1800 lb-in to 10,000  lb-in.
     • Maximum operating pressure: 3000 psi (207 Bar)
     • Operating temperature range:
      o Nitrile seals -40° to 180°F  or -40° to 82°C
     • Standard rotations: 90°
     • Rotational tolerance: -0°, +2°
     • Maximum breakaway pressure: 70 psig or 4.8 Bar
     • Mounting orientation: unrestricted
     • Standard timing: keyway in 12:00 position at midstroke
     • Recommended filtration: ISO class 17/14 or better

    Rack and pinion design provides excellent efficiency characteristics (90-95%) and minimizes HPU Size
    Direct mounting design to numerous process valves allows for minimal integration cost
    Integrated valve modules options are available for increased performance and reduced plumbing cost
      • Cross over vent module - allows for flow between both cylinder ports
      • Counter-balance valve module with cross over vent - designed for load holding in both directions
         and preventing a run-awayload situation from occurring. Also allows for flow between both cylinder ports.
      • D03 Solenoid ready module - manifold block directly mounted to actuator for reduced plumbing and
         increase in performance
    Numerous linear and positional feedback and visual indication options available
    Environmentally rugged for reliable performance in harsh conditions
