A mechanical device that converts compressed air energy into linear mechanical force and motion.

Product Specifications

Technical details and manufacturing context for Pneumatic Cylinder

Definition
A pneumatic cylinder is a key component within pneumatic systems that uses compressed air to create reciprocating linear motion. It consists of a cylindrical chamber, piston, piston rod, and end caps, and serves as the primary actuator for moving, lifting, pushing, or pulling loads in automated industrial applications.
Working Principle
Compressed air enters the cylinder through ports, creating pressure differentials that force the piston to move along the cylinder bore. The piston's linear motion is transferred through the piston rod to perform mechanical work. Directional control valves regulate air flow to extend or retract the cylinder.
Common Materials
Aluminum alloy, Stainless steel, Carbon steel

Downstream Applications
Specialized Tooling

Application Fit & Sizing Matrix

Operational Limits
pressure: Up to 10 bar (150 psi)
other spec: Flow rate: 0.1-100 L/min, Slurry concentration: Not applicable (clean, dry air required)
temperature: -20°C to 80°C
Media Compatibility
✓ Clean, dry compressed air ✓ Inert gases (e.g., nitrogen) ✓ Non-corrosive industrial atmospheres
Unsuitable: High-moisture or corrosive environments (e.g., salt spray, chemical exposure)
Sizing Data Required
  • Required force (N or lbs)
  • Stroke length (mm or inches)
  • Operating pressure (bar or psi)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Seal degradation
Cause: Contamination ingress (dust, moisture, particulates) leading to wear, chemical incompatibility with lubricants or process media, or excessive temperatures beyond seal material limits.
Rod scoring or bending
Cause: Misalignment during installation or operation, side-loading forces, inadequate rod support (e.g., missing or worn rod guides), or ingress of abrasive contaminants.
Maintenance Indicators
  • Audible hissing or air leakage around cylinder seals or fittings during operation
  • Erratic or jerky motion, slow extension/retraction, or failure to reach full stroke
Engineering Tips
  • Implement proper air preparation: use filtered, lubricated, and dry compressed air with regulators set to manufacturer-specified pressure to prevent contamination and moisture damage.
  • Ensure precise alignment during installation and use appropriate mounting hardware (e.g., clevis mounts with pivot points) to minimize side-loading and extend rod and seal life.

Compliance & Manufacturing Standards

Reference Standards
ISO 15552:2004 (Pneumatic fluid power - Cylinders) ANSI/NFPA T3.6.7 R1-2015 (Fluid power cylinders - Bore and rod area - Metric series) DIN ISO 6431 (Pneumatic cylinders - 1000 kPa (10 bar) series)
Manufacturing Precision
  • Bore diameter: +/-0.02 mm
  • Rod straightness: 0.1 mm per 100 mm length
Quality Inspection
  • Pressure test (leakage and burst)
  • Dimensional verification (bore, rod, mounting dimensions)
