High-force industrial cylinder optimized for heavy-duty linear motion applications. Features precision honed tube for smooth operation and wear-resistant seals for 3,000km+ service life. The anodized body resists chemical corrosion in harsh environments.

Typical Industrial Applications:
  • Metal stamping press ejection systems
  • Automotive welding fixture clamping
  • Foundry equipment material handling
  • Construction machinery braking actuators
  • Plastic injection molding machine gates
Installation guidelines: Use locknuts (M20×1.5) with 40-50 N·m torque on piston rod threads. Maintain 0.5mm minimum lateral clearance during alignment. Lubricate through air port with ISO VG32 turbine oil during initial installation.
⚠️ Critical parameters:
  • Maximum side load capacity: 850 N
  • Theoretical output force (@0.6MPa): 7,350 N (extend), 6,890 N (retract)
  • Maximum piston speed: 500 mm/s
  • Air consumption per cycle (@0.6MPa): 7.3 liters
