High-precision dual rod cylinder featuring position-lockable adjustment collars for precise stroke control. The symmetrical rod design eliminates rotational torque, making it ideal for precision alignment applications. Corrosion-resistant construction with IP54 protection rating ensures reliability in harsh environments.

Typical Applications:
  • Precision clamping fixtures in CNC machining centers
  • Vertical lift mechanisms for semiconductor wafer handling
  • Parallel gripper systems in robotic automation
  • Position-stabilized platforms for optical inspection equipment
  • Sheet metal bending machine backgauges
Installation guidelines: For optimal performance, align within 0.2mm/m using precision levels during mounting. Allow minimum 5mm clearance around adjustment collars for stroke modification. Lubricate rods monthly with ISO VG32 hydraulic oil in high-cycle applications (>500k cycles/year).
Stroke Adjustment:
  1. Loosen lock nuts on both end collars
  2. Rotate collars to desired position (1 rotation = 1.5mm adjustment)
  3. Retighten nuts to 2.5N·m torque using a calibrated wrench
  4. Perform test strokes before full operation
