A space-saving pneumatic actuator featuring micrometer-style stroke adjustment (±1mm precision) through its rotating end cap. The integrated locknut maintains position stability during vibration. Its anodized surface resists corrosion in humid environments, while the dual cushioning system enables smooth operation up to 3 m/s piston speed.

Typical Applications:
  • Precision clamping in PCB assembly robots
  • Feed mechanisms in semiconductor packaging
  • Valve actuation in laboratory analyzers
  • Position adjustment in optical alignment systems
  • Ejector systems in micro-injection molding
Installation note: For optimal performance, maintain 0.5-1mm clearance between the adjustable stopper and rod end during calibration. Lubricate with ISO VG32 hydraulic oil if operating below 0.3 MPa. Avoid side-load exceeding 15N.
