Description
    Designed to meet steel mill specifications, these non-tie rod units incorporate a range of features that provide heavy duty dependable service. The heat treated pinions provide low tooth contact pressures and permit hollow shaft configurations with bore sizes capable of transmitting full operating torques, including shock loadings. The M Series units are fitted with wear ring bushings that provide full support and eliminate the possibility of contact between the cylinder and piston. The large diameter tapered roller bearings on the pinion allow the actuator to absorb considerable thrust, radial and overhung loads. For ease of maintenance, all pressure seals on M Series can be inspected or replaced without removing the actuator from the customer's shaft.

      • Output torques @ 3000 psi (207 bar): 75,000 lb.-in to 50,000,000  lb-in.
      • Maximum operating pressure: 3000 psi (207 bar)
      • Operating temperature range:
        o Nitrile seals: -40° to 180°F  or -40° to 82°C
        o Fluorocarbon seals: -20° to 250°F  or -29° to 121°C
      • Standard rotations: 90°, 180°, 360°
      • Rotational tolerances: -0°, +2°
      • Maximum breakaway pressure: 75 psi  or 5 bar
      • Mounting orientation: unrestricted
      • Timing: Keyway located at 12:00 position at midstroke of actuator
      • Housing:
        o Heavy duty ductile iron (units up to 1000M),
        o Steel weldments (units larger than 1000M)

    Rack and pinion design provides excellent efficiency characteristics (90-95%) and minimizes HPU Size
    Minimal heat build up, limits need for heat exchanger
    Large hollow gears offer more shaft options
    M series are designed for low wear on dynamic seals and longer life
    Excellent in high speed production applications
