This compact cylinder combines precise linear motion with space-saving design, featuring 360° adjustable cushioning screws for optimal impact control. The hard-anodized barrel provides exceptional wear resistance in dusty environments. Unique dual guide rod configuration ensures anti-rotation stability during operation.

Common Applications:
  • PCB handling robots in electronics manufacturing
  • Precision clamping fixtures for CNC machining centers
  • Medical device assembly automation
  • Packaging machine ejector mechanisms
  • Automotive component testing equipment
Installation Guidelines:
  • Align cylinder axis within 0.2mm perpendicular tolerance
  • Use flexible couplings for stroke-end load absorption
  • Install upstream 5μm filter regulator for clean air supply
  • Allow 25mm maintenance clearance at cushion adjustment points
Maintenance tip: Inspect rod seals every 500,000 cycles in normal operation. Replace buffer seals when cushioning performance degrades by >30%. Avoid side-load exceeding 15N·m.
