  • Bore size: 25mm (±0.13mm tolerance)
  • Stroke range: 25-500mm (customizable)
  • Operating pressure: 0.05-1.0 MPa
  • Cushioning: Adjustable elastic cushion (both ends)
  • Piston speed: 50-800mm/s
  • Ambient temperature: -20℃ to 80℃
  • Port size: M5x0.8 (standard), G1/8 optional
  • Rod thread: M6x1.0 (external)
  • Mounting type: Basic (AX series) with NAMUR mounting pattern
  • Seal material: NBR (Nitrile) with integrated wear ring
  • Magnetic sensor compatibility: DC 3-30V (requires separate sensor purchase)
  • Weight: 0.35kg (base model with 25mm stroke)
  • Dimensions (L×W×H):
    • Body diameter: 40mm
    • Stroke length tolerance: ±1.5mm
    • Total length: 125mm (25mm stroke) + stroke adjustment
    • Rod end thread length: 12mm
  • Protection rating: IP65 (standard wipers)
  • Lubrication: Pre-lubricated (Grease-free operation possible)

High-precision industrial cylinder featuring chrome-plated piston rod (HCF hardness ≥700HV) and anodized aluminum barrel. Designed for high cycle rates (up to 5 million cycles at rated load) with minimal stick-slip effect. Includes built-in magnet for position feedback when used with compatible sensors.

Typical Applications:
  • Pick-and-place automation in SMT equipment
  • Clamping mechanisms in CNC fixtures
  • Material handling systems with position feedback requirements
  • Pharmaceutical packaging line actuators
  • Cleanroom compatible when using optional stainless steel version
Installation guidelines: Maximum side load ≤10% of dynamic thrust. For vertical mounting, use stroke end locking nuts. Lubricate every 5 million cycles with ISO VG32 hydraulic oil. Magnetic sensors must maintain 0.5-1.5mm air gap from cylinder surface.
Performance Data: Theoretical force output @0.6MPa:
  • Thrust (extending): 29.4kgf
  • Pull force (retracting): 26.5kgf
  • Maximum permissible kinetic energy: 0.15J
