Ultra-compact profile cylinder featuring micrometer-style stroke adjustment (±1mm precision) through dual locknuts. The hardened piston rod and double-seal structure ensure leak-free operation in high-cycle applications. Includes built-in magnet for position sensing compatibility.

Industrial Applications:
  • Precision clamping in semiconductor wafer handling
  • Valve actuation in medical diagnostic equipment
  • Cartesian robot Z-axis positioning mechanisms
  • Food packaging machine stopper adjustment
  • PCB press-fit component insertion systems
Installation tip: When using stroke adjustment, always tighten locknuts in sequence (inner nut first) and apply thread-locking compound. Maintain 0.5mm minimum stroke buffer to prevent piston-to-endcap collision.
Fluid Requirements: Lubricated or non-lubricated air (ISO8573-1:2010 Class 3.4.2), with 40μm filtration recommended. For vertical mounting, install drip cups if using oil-mist lubrication.
