A heavy-duty ISO-compliant pneumatic cylinder featuring precision honed tubing and dual anti-rotation design. The SCJ40 series delivers 482N thrust at 0.6MPa (extend) with ≤0.5mm/s creep speed. Includes magnetic piston version option (add "-M" suffix) for position sensing.

Industrial Applications:
  • Automated assembly line clamping units
  • Die-casting machine ejection systems
  • Palletizing robot end-effectors
  • Textile machinery tension control
  • CNC fixture positioning mechanisms
Installation guidelines: Maximum side load capacity 35N. Use with AR-12 type rod clevis for optimal alignment. Lubricate every 3,000km stroke travel. Avoid rapid pressure changes >0.3MPa/100ms to prevent seal damage.
