High-force industrial cylinder designed for heavy-duty linear motion applications. Features oversized piston rod (Ø45mm) for enhanced buckling resistance and precision honed inner tube surface (Ra≤0.2μm) for smooth operation. Optional magnetic piston version (SGC250X40S-M9) available for position sensing.

Typical Applications:
  • Press machine clamping mechanisms
  • Steel mill door actuators
  • Plastic injection molding ejectors
  • Automotive welding fixture positioning
  • Heavy conveyor gate controls
Installation tip: For vertical mounting, use auxiliary rod-end support when stroke exceeds 300mm. Maintain 0.5mm minimum alignment tolerance between rod and load connection.
Maintenance: Replace cushion seals every 500,000 cycles in high-speed applications (>1 m/s). Use ISO VG32 hydraulic oil if manual relubrication required.
