A canonical Cylinder Body (Pneumatic) is characterized by the integration of Cylinder Bore and Mounting Holes/Brackets. In industrial production environments, manufacturers listed on CNFX commonly emphasize Aluminum alloy construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The main structural housing of a pneumatic cylinder that contains the piston and compressed air.

Product Specifications

Technical details and manufacturing context for Cylinder Body (Pneumatic)

Definition
The cylinder body is the primary structural component of a pneumatic actuator that forms a sealed chamber where compressed air acts on a piston to generate linear motion. It provides mounting points, contains pressure, and guides the piston rod.
Working Principle
The cylinder body serves as a pressure vessel that contains compressed air. When air enters through ports, it creates differential pressure across the piston, causing linear motion. The body maintains structural integrity under pressure and provides a smooth bore for piston movement.
Common Materials
Aluminum alloy, Stainless steel, Carbon steel
Technical Parameters
  • Bore diameter (inner diameter) of the cylinder body (mm) Standard Spec
Components / BOM
  • Cylinder Bore
    Provides smooth surface for piston movement and maintains seal integrity
    Material: Hardened steel or chrome-plated steel
  • Mounting Holes/Brackets
    Secure the cylinder body to machinery or frames
    Material: Same as main body material
  • Air Ports
    Entry and exit points for compressed air to actuate the piston
    Material: Brass or steel with threaded connections
  • End Caps
    Seal the ends of the cylinder body and provide mounting for rod guides
    Material: Aluminum alloy or steel
Engineering Reasoning
0.1-16 MPa (1-160 bar)
20 MPa (200 bar) burst pressure for ISO 15552 standard cylinders
Design Rationale: Hoop stress exceeding yield strength (σ_θ = P·D/(2t) > σ_y), where P=internal pressure, D=inner diameter, t=wall thickness, σ_y=250-350 MPa for aluminum alloy 6061-T6
Risk Mitigation (FMEA)
Trigger Corrosive fluid ingress (pH <4 or >10)
Mode: Wall thinning from pitting corrosion at 0.5-2.0 mm/year rate
Strategy: Anodized coating (25-50 μm thickness) with PTFE impregnation
Trigger Lateral loading exceeding 15% of axial force
Mode: Bore scoring from piston rod misalignment >0.1 mm/m
Strategy: Integrated rod guide bearing with 0.02-0.05 mm clearance

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Seal degradation
Cause: Contamination ingress (dust, moisture, particles) leading to wear, chemical attack from incompatible lubricants or environmental exposure, or excessive heat from high-cycle operation or poor lubrication.
Cylinder bore scoring or wear
Cause: Abrasive particles in the air supply due to inadequate filtration, misalignment causing side loading and uneven wear, or corrosion from moisture in the compressed air system.
Maintenance Indicators
  • Audible hissing or air leakage around the cylinder body or rod seals, indicating seal failure.
  • Visual scoring, scratches, or corrosion on the cylinder rod or visible wear marks on the external body, suggesting internal damage or contamination.
Engineering Tips
  • Implement and maintain proper air filtration (e.g., 5-micron filters with coalescing elements) and drying systems to remove moisture and particulates from the compressed air supply.
  • Ensure correct alignment during installation, use appropriate lubricants compatible with seal materials, and adhere to regular preventive maintenance schedules including seal inspection and lubrication.
