AirTAC SI40X206 Standard Cylinder Specifications

  • Model: SI40X206
  • Type: ISO 15552 compliant double-acting cylinder
  • Bore size: 40mm
  • Stroke: 200mm (Standard) + 6mm tolerance (indicated by "206")
  • Operating pressure: 0.1-1.0 MPa
  • Cushioning type: Adjustable pneumatic cushion (both ends)
  • Piston rod material: Chrome-plated steel (Cr-Mo)
  • Tube material: Anodized aluminum alloy
  • Seal material: NBR (Nitrile rubber) with wear-resistant ring
  • Mounting style: Standard ISO mounting (optional accessories: MA1/MS1/MF1)
  • Operating temperature: -20℃ to 80℃
  • Weight: 2.15kg (without accessories)
  • Dimensions:
    • Extended length: 398mm (stroke 200mm)
    • Retracted length: 198mm
    • Body diameter: 52mm
    • Mounting hole spacing: 30mm (front) / 48mm (rear)
  • Port size: G1/8 (standard) or optional NPT1/4
  • Max theoretical thrust: 1256N at 0.63MPa
  • Lubrication: Pre-lubricated (optional oil-free operation)

The SI40X206 features a precision-ground piston rod with dual sealing system for leak-proof operation. Its auto-switch ready design (with T-slot) enables easy sensor integration. The anodized barrel resists corrosion in humid environments, while the reinforced end caps withstand 1.5x rated pressure.

Industrial Applications:
  • Automated assembly line clamping mechanisms
  • Plastic injection molding machine ejectors
  • CNC machine tool door interlocks
  • Automotive welding fixture positioning
  • Food processing conveyor gate actuators
Installation protocol: Align cylinder axis with motion direction within ±0.5° tolerance. Use anti-vibration washers when mounting to stamped steel surfaces. For vertical installations, install rod-down orientation to prevent condensate accumulation.
Cycle life: 5,000km travel distance (NBR seals) or 3,000km (oil-free operation) under standard conditions. Relubricate every 3 million cycles using ISO VG32 hydraulic oil.
