Hydraulic Rotary Actuator - Tork-Mor Series (vane) | Parker NA

Hydraulic Rotary Actuator - Tork-Mor Series (vane)

The Tork-Mor Series is available in 18 sizes with 145K lb-in of torque. Capable of providing full torque instantly in either direction, it is available with 100° or 280° rotation. The Tork-Mor can be mounted in any axis with numerous mounting options.

    Tork-Mor series actuators are produced in eighteen sizes generating up to 145,000 lb-in of torque at rated pressure. Capable of providing full torque instantly in either direction, they are available with 100° or 280° rotation at pressures up to 1000 psi. The Tork-Mor series can be mounted in any axis using a wide variety of standard or optional mountings. Proven reliable through many years of field service, the Tork-Mor series incorporates many quality features including precision ball bearings to provide shaft support, externally removable gland for ease of seal replacement, and cylinders honed to a 10 micro inch finish to ensure long seal life.

     • Output torques @ 500 psi (35 Bar): 800 lb-in to 142,000  lb-in.
     • Maximum operating pressure: 1000 psi (69 Bar) hydraulic
     • Operating temperature range:
      o Nitrile seals -40° to 180°F (-40° to 82°C)
      o Fluorocarbon seals -20° to 250°F (-29° to 121°C)
     • Rotations:
       o S Models – 280°
       o DS Models – 100°
     • Rotational tolerance: ± 1°:
     • Max. allowable drain line pressure : 50 psi (hydraulic)
     • External shaft load capacities:
       o Thrust Loads: Units have no thrust load capacity.
       o Radial Loads: External radial loads are not recommended and can reduce the life of the unit. Consult factory
           before applying.

    Vane design provides fair efficiency characteristics (75-85%)
    Limited rotation and torque range
    Small package size is suitable for application with space constraints
    Precision positioning is achieved due to no backlash design
    Suited for medium speed production applications
