Precision-engineered adjustable stroke cylinder featuring dual-position cushion locking nuts for millimeter-level stroke adjustment. The SEJ50X100-40S combines 500,000+ cycle durability with ±0.5mm repeat positioning accuracy, achieved through its precision-ground rod and triple-lip seal design. Includes anti-rotation guide for stable vertical operation.

Industrial Applications:
  • Precision clamping in CNC fixture systems
  • Variable height adjustment in packaging conveyors
  • Material positioning in semiconductor handling robots
  • Pressure-sensitive assembly processes (e.g., electronics manufacturing)
  • Variable stroke applications requiring frequent tooling changes
Installation protocol: Apply thread lock (Loctite 243 recommended) on mounting bolts. For stroke adjustment: Loosen lock nut (M8), rotate cushion screw (clockwise to reduce stroke), then re-tighten to 1.2-1.5N·m torque. Maintain 0.3-0.5MPa lubricated air supply.
