High-precision industrial cylinder featuring micrometer-style stroke adjustment (50mm minimum stroke reduction) through dual external locking nuts. The anodized barrel resists chemical corrosion, while the triple-lip wiper seal prevents contaminant ingress. Includes magnetic piston for sensor compatibility and anti-rotation guide to maintain orientation during stroke adjustment.

Industrial Applications:
  • Variable height positioning in automotive assembly jigs
  • Pressure-sensitive material handling systems
  • Plastic injection molding ejector mechanisms
  • Printing press roller engagement systems
  • Food processing line adjustable divert gates
Operation tip: Always depressurize before adjusting stroke. Use 0.3-0.5mm thick shim washers when mounting to prevent flange deformation. Lubricate adjustment threads monthly with ISO VG32 hydraulic oil.
