High-precision short-stroke cylinder featuring dual cushioning system and corrosion-resistant construction. The SAU40X20S employs a multi-lip seal design achieving ≤0.5mm/s creep speed at 0.3MPa. Requires ISO VG32 hydraulic oil mist lubrication (0.3cm³/min minimum).

Industrial Applications:
  • Precision clamping in CNC tool changers
  • Valve actuation in semiconductor wafer handling
  • High-cycle press brake tool positioning
  • Packaging machine gate control (≤60 cycles/min)
  • Medical device assembly automation
Installation protocol: Maximum side load ≤15% of thrust rating. For vertical mounting, use counterbalance valve when holding loads >3kg. Lubricate through air supply (oil-fog lubrication) with 5-7μm filtration.
