High-thrust ISO-compliant pneumatic cylinder optimized for heavy-duty industrial applications. Features dual magnetic sensors (built-in slot for D-M9N series switches) and corrosion-resistant construction. The triple-lip wiper seal prevents particulate ingress in harsh environments.

Typical Applications:
  • Press machine ejection systems
  • Automotive welding fixture actuation
  • Steel mill material handling gates
  • Plastic injection molding machine core pulls
  • Palletizing robot end effectors
Installation tip: For vertical mounting exceeding 45° angle, install an external mechanical lock to prevent unintended movement during pressure loss. Lubricate through air port using ISO VG32 hydraulic oil if non-lubricated operation is required.
Maintenance: Inspect rod seals every 500,000 cycles in standard operation. Use 40μm filtration for compressed air. When replacing seals, ensure complete removal of metal particles from rod surface to prevent scoring.
