High-precision compact cylinder featuring micrometer-style stroke adjustment mechanism with locking nut. The dual-cushion design minimizes end-impact noise while maintaining positioning accuracy (±0.5mm repeatability). Anti-rotation guide slots ensure stable linear motion, ideal for space-constrained automation setups requiring fine position control.

Common Applications:
  • PCB handling robots in electronics assembly
  • Precision clamping fixtures for CNC machining
  • Dispenser head positioning in adhesive applications
  • Optical lens alignment systems
  • Medical device testing equipment
Installation guidelines: Use Loctite 243 on adjustment screws during final calibration. Maintain 0.5-1mm clearance between cylinder body and adjacent components for thermal expansion. For vertical mounting, install exhaust mist lubricator (AM200 series recommended).
Pressure Caution: Do not exceed 1.2MPa momentary pressure. When using in vacuum applications (below atmospheric pressure), install vacuum-rated seals (option code /V).
