Ultra-compact linear actuator featuring external stroke adjustment mechanism with ±1mm repeatability. The anodized barrel provides corrosion resistance while the chrome-plated rod ensures smooth operation. Integrated shock absorbers minimize end-impact noise. Requires 5μm filtered air for optimal performance.

Typical Applications:
  • Precision positioning in semiconductor handling robots
  • Labeling machine feeder mechanisms
  • Medical device assembly lines
  • Automated test equipment with space constraints
  • Pharmaceutical packaging systems
Installation note: Ensure proper rod alignment (<0.1° angular misalignment max). For vertical mounting, use rod-end support brackets. Lubricate every 500km stroke travel with ISO VG32 hydraulic oil.
WARNING: Do not exceed maximum side load capacity of 15N. When using full 400mm stroke, maintain ambient temperature below 60℃ to prevent thermal expansion errors.
