  • Stroke: 80mm (adjustable cushioning)
  • Operating pressure: 0.15–0.8 MPa (1.5–8 bar)
  • Medium temperature: -20℃ to 80℃ (dry air required below 0℃)
  • Cushion type: Adjustable air cushion (both ends)
  • Mounting style: Basic type (MF1) with front flange
  • Port size: PT1/4 (NPT1/4 optional)
  • Piston speed: 50–750 mm/s (optimal at 500 mm/s)

High-precision industrial cylinder featuring wear-resistant rod treatment and precision honed tube. The dual piston seal design ensures ≤0.5mm/s leakage rate under 6 bar pressure. Anti-rotation mechanism prevents rod spinning during operation. Optional magnetic piston version (JSI40X80S-M9) available for position sensing.

Typical Applications:
  • Clamping fixtures in CNC machining centers
  • Conveyor gate actuation systems
  • Packaging machine ejection mechanisms
  • Automotive welding jig positioning
  • Food processing equipment (stainless steel rod option)
Installation notes:
  • Lubricate with ISO VG32 hydraulic oil if using non-lubricated air
  • Maintain 0.3–1.0mm alignment tolerance during mounting
  • For vertical mounting, use rod-down orientation to prevent condensate ingress
  • Allow 15mm clearance behind cushion screws for adjustment
Critical Parameters:
  • Max side load: 25N at mid-stroke
  • Lifetime: 5,000km travel distance (NBR seals)
  • Re-lubrication interval: 3 months continuous operation
  • Breakaway pressure: ≤0.08 MPa
