Product Specifications

Technical details and manufacturing context for Actuator Cylinder

Definition
An actuator cylinder is a key component in actuation mechanisms that uses pressurized fluid (hydraulic or pneumatic) to generate controlled linear force and motion. It typically consists of a cylindrical barrel, piston, piston rod, and seals, and serves as the primary force-generating element in various industrial automation and machinery systems.
Working Principle
Pressurized fluid enters the cylinder chamber, creating pressure differential across the piston. This pressure differential generates force on the piston surface, causing the piston rod to extend or retract linearly. The direction of motion is controlled by fluid flow direction via valves.
Common Materials
Carbon Steel, Stainless Steel, Aluminum Alloy
Technical Parameters
  • Bore diameter - determines force output based on pressure and piston area (mm) Customizable
Components / BOM
  • Cylinder Barrel
    Houses piston and fluid, provides structural integrity
    Material: Steel or Aluminum
  • Piston
    Separates fluid chambers, transmits force to rod
    Material: Steel with Seals
  • Piston Rod
    Transmits linear force to external mechanism
    Material: Hardened Steel
  • End Caps
    Seal cylinder ends, provide mounting points
    Material: Steel or Cast Iron
  • Seals
    Prevent fluid leakage between chambers
    Material: Polyurethane or Nitrile Rubber
Engineering Reasoning
1.5-350 bar
420 bar (burst pressure) or 0.8 bar (minimum operating pressure)
Design Rationale: Material yield strength exceeded at 420 bar (SAE 1018 steel: 370 MPa yield) causing permanent deformation; below 0.8 bar, insufficient force generation leads to stiction and seal leakage due to pressure differential < seal design threshold
Risk Mitigation (FMEA)
Trigger Hydraulic fluid contamination > ISO 4406 18/16/13
Mode: Spool valve abrasion causing 15% flow reduction
Strategy: Install 3 μm absolute filtration with differential pressure monitoring at 0.7 bar
Trigger Piston rod side-load > 0.5 mm misalignment per 100 mm stroke
Mode: Asymmetric seal wear leading to 25 ml/min external leakage
Strategy: Integrate rod alignment guide with 0.05 mm tolerance and load cell feedback
