Precision-engineered adjustable stroke cylinder featuring twin mechanical stop collars for ±1mm stroke positioning accuracy. The hardened piston rod and multi-lip seal design ensure over 3,000km service life under standard conditions. Integrated cushioning adjustment screws allow fine-tuning of end-position deceleration.

Industrial Applications:
  • Pick-and-place robot end effectors requiring variable grip positions
  • Packaging machine flap adjustment mechanisms
  • CNC fixture positioning systems
  • Semiconductor handling equipment with space constraints
  • Automated test equipment requiring repeatable stroke adjustments
Installation recommendation: Use Loctite 243 on adjustment collar threads. For vertical installations exceeding 0.5m/s speed, specify the optional magnetic piston version (MKJ25X25-20/M) for position feedback.
Operation guidelines:
  • Maximum side load: 15N at rod end
  • Recommended air filtration: 40μm with auto-drain
  • Re-lubrication interval: Every 1,000km travel or 6 months
  • Torque limits: 3.5N·m max on mounting bolts
