  • M series (Heavy Duty) – Hydraulic Rotary Actuators
    ~ scroll down to find the part you need ~
    The Heavy Duty M series actuators are 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 the 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: Nitrile seals: -40° to 180°F or -40° to 82°C. 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: Heavy duty ductile iron (units up to 1000M) Steel weldments (units larger than 1000M)
      Rack and pinion design provides excellent efficiency characteristics (90-95%) and minimizes Hydraulic Power Unit Size. Minimal heat build-up, limits the need for heat exchangers. 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.

  • HTR Series - Hydraulic Rotorary Actuator
    ~ scroll down to find the part you need ~
    The HTR Series rotary actuator incorporates many hydraulic and mechanical features that make this actuator robust and ideal for the most demanding high production applications. Features include: high load capability tapered roller bearings; a chrome alloy steel rack and pinion gear set; a high strength ductile iron or steel housing; and proven Parker Hannifin cylinder components. The HTR Series actuators have been successfully employed in multiple applications including automotive plant production machinery; machine tool equipment; plastics and rubber processing machinery; basic metals production machinery and in material handling machinery. The HTR Series can be employed as an integral machine component, where the actuator can simultaneously transmit torque and support the line shaft or the load. Such an arrangement allows for the elimination of one set of external support bearings. Optional cushions can also be incorporated to decelerate external loads, thus eliminating the need for an external deceleration device such as shock absorbers or brakes. Additionally, machine installations can be simplified with the hollow shaft feature by eliminating additional coupling. This is achieved by means of a square shaft key or if needed the housing can be drilled and tapped to mount various brackets. For easy serviceability, the piston seals can be inspected and replaced while the actuator remains installed on the machinery.
