Description
    The LTR series rotary actuator is ideal for low pressure hydraulic applications. The LTR Series actuator combines an alloy steel gear set with a high strength aluminum housing and Parker 3L or 2A Series cylinder components into an actuator suitable for years of trouble free service. The actuator maximizes volumetric efficiency by using self-energizing PolyPak seals. Mechanical efficiency is maximized by using antifriction bearings and Wear-pak® piston technology.

      • Output torques @ 1000 psi (69 bar): 395 lb.-in to 22,813 lb-in.
      • Nominal pressure: 1000 psig (69 bar) (3L cylinder pressure ratings apply)
      • 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°, 270°, 360°, 450°
      • Rotational tolerance: -0°, +2°
      • Maximum breakaway pressure: 30 psig or 2 bar
      • Mounting orientation: unrestricted
      • Standard timing: Keyway in 12:00 position at midstroke
      • Recommended filtration: ISO class 17/14 or better
      • Hydraulic cushions to minimize noise, vibration shock and assist deceleration control
      • Reed, Hall Effect or proximity switches for position sensing
      • End-of-rotation stroke adjusters for load position control and accurate rotation adjustment
      • Built-in meter out flow control valves with reverse flow check valves provide a neat package
      • Three position option can be used with many special machine and material handling applications

    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
    LTR series are designed for low wear on dynamic seals and longer life
    Excellent in high speed production applications

    Markets/Applications
      • Aerospace/water bomb, tank door actuation
      • Automation/mounting, processing, flood gate actuation, end of arm tooling
      • Conveyor/swing and rotate
      • Mobile/fire truck ladder rotation, aerial lift basket, X-ray boom rotation, forklift handling & storage, refuse tippers
      • Transportation/bus wheelchair ramp
