The XR Series is a small rack & pinion designed actuator that combines carburized and tempered steel gear sets with a precision aluminum extrusion housing. These actuators are suitable for applications where space is a premium and low torques are needed.

  • Output torques @ 100 psi (6.9 Bar): 6 & 236 lb-in
  • Maximum pressure: 100 psig (6.9 Bar)
  • Operating temperature range:
      o Nitrile seals 0 to 180° F (-18° to 82°C)
      o Fluorocarbon seals 0° to 250°F (-18 to 121°C)
  • Standard rotations: 90°, 100°, 180°, 190°, 270°, 280°, 360°, 370°
  • Rotational tolerance:
        o XR05: -0°, +8°
        o XR07: -0°, +6°
        o XR10: -0°, +5°
        o XR15: -0°, +4°
        o XR20: -0°, +3°
  • Maximum breakaway pressure:
        o XR05: 10 psig (.7 Bar)
        o XR07: 7 psig (.5 Bar)
        o XR10, 15, 20: 5 psig (.4 Bar)
  • Mounting orientation: unrestricted
  • Standard timing: Keyway in 12:00 position at midstroke
  • Recommended filtration: 40 micron filtered, dry air
  • Pneumatic cushions to minimize noise, vibration shock and assist deceleration control
  • End-of-rotation stroke adjusters for load position control and accurate rotation adjustment
  • Polyurethane bumpers to absorb shock & noise, thus permitting faster cycle times and increased production
  • Built-in anti-backlash option for precision positioning
  • Reed and Hall Effect sensors available for position sensing
