Product Specifications

Technical details and manufacturing context for Actuator (Cylinder)

Definition
A mechanical actuator component within a Material Hold-Down System that converts fluid power (pneumatic or hydraulic pressure) into controlled linear force and motion. It functions to securely clamp, press, or hold materials in place during manufacturing processes such as cutting, welding, assembly, or forming, ensuring precision and stability by applying consistent downward or lateral pressure.
Working Principle
Operates by introducing compressed air or hydraulic fluid into a sealed chamber, which forces a piston to move linearly along the cylinder bore. This motion is transmitted through a piston rod to the hold-down mechanism. Directional control valves regulate the flow to extend or retract the actuator, while pressure regulators adjust the clamping force applied to the material.
Common Materials
Aluminum alloy, Stainless steel, Carbon steel

Downstream Applications
Specialized Tooling

Application Fit & Sizing Matrix

Operational Limits
pressure: Up to 300 bar hydraulic, 10 bar pneumatic (typical)
flow rate: Dependent on cylinder bore size and required speed (calculate from Q = A × v)
temperature: -20°C to 120°C (standard seals), -40°C to 200°C (special seals)
slurry concentration: Not applicable for standard cylinders; requires special rod seals/wipers for contaminated environments
Media Compatibility
✓ Hydraulic oil (mineral-based) ✓ Compressed air (filtered, lubricated) ✓ Water-glycol hydraulic fluids
Unsuitable: Chlorinated solvents or highly corrosive chemicals without special material construction
Sizing Data Required
  • Required force (kN 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 (dirt, moisture), chemical incompatibility with fluids, or excessive heat causing hardening/cracking
Rod scoring/wear
Cause: Misalignment creating side-loading, inadequate lubrication, or abrasive particles in the system damaging the rod surface
Maintenance Indicators
  • Audible hissing or air leakage during operation indicating seal failure
  • Visible fluid leaks around rod seals or cylinder body connections
Engineering Tips
  • Implement proper filtration (5-10 micron) and moisture removal in pneumatic/hydraulic systems to prevent contamination
  • Ensure correct cylinder mounting alignment and use rod supports on long-stroke applications to prevent side-loading

Compliance & Manufacturing Standards

Reference Standards
ISO 15552: Pneumatic fluid power - Standard cylinders ANSI/NFPA T3.6.7 R1-2015: Fluid power cylinders - Method for verifying the fatigue and establishing the burst pressure ratings of the pressure containing envelope DIN ISO 6432: Pneumatic fluid power - Single rod cylinders, 10 bar (1000 kPa) series, bores from 32 mm to 320 mm
Manufacturing Precision
  • Bore diameter: +/-0.02 mm
  • Rod straightness: 0.1 mm per 1000 mm length
Quality Inspection
  • Pressure test: Hydrostatic/pneumatic leak and burst pressure verification
  • Dimensional inspection: CMM (Coordinate Measuring Machine) verification of critical tolerances
