A high-performance ISO-standard pneumatic cylinder featuring precision-machined components and triple sealing system. The JSI40X140S combines corrosion-resistant aluminum construction with wear-resistant rod guides, optimized for high-cycle applications. Includes magnetic piston version (JSI40X140S-M) for position sensing compatibility.

Industrial Applications:
  • Automated packaging line actuators
  • CNC machine tool clamping mechanisms
  • Automotive welding fixture positioning
  • Food processing conveyor gate controls
  • Pharmaceutical blister packing machines
  • Plastic injection molding ejectors
Installation guidelines: Maintain 0.5mm minimum alignment tolerance during mounting. For vertical installations exceeding 45° angle, use rod-end support brackets (ASM-40 accessory recommended). Lubricate through air port using ISO VG32 turbine oil before initial operation.
Cycle Life: 5,000km stroke life under standard conditions (20℃, clean dry air). Double-life seals available (JSI40X140S-L7 version) for dusty environments.
