High-precision adjustable stroke cylinder featuring dual micro-adjustment mechanisms (hex wrench included). The SEJ series combines position memory capability with dual cushion control, allowing mid-stroke positioning through external mechanical stoppers. The anodized barrel surface resists chemical corrosion in harsh environments.

Industrial Applications:
  • Variable height positioning in automated assembly lines
  • Pressure-sensitive clamping systems (electronics manufacturing)
  • Material handling with adjustable stroke requirements
  • Packaging machinery with product size variations
  • Plastic injection molding ejection systems
Installation guidance: For optimal performance, maintain 0.5-1mm clearance between mechanical stopper and cylinder rod. Lubricate with ISO VG32 hydraulic oil before initial operation. Avoid side load exceeding 30N during adjustment.
