Ultra-compact cylinder featuring precision-machined aluminum alloy construction with hard anodized finish. The dual adjustable air cushions minimize impact noise while allowing ±2mm stroke fine-tuning capability. Integrated auto switch groove (4mm width) enables sensor mounting for position feedback.

Typical Applications:
  • PCB handling robots in electronics manufacturing
  • Precision clamping in optical lens assembly
  • Medical device actuator mechanisms
  • Semiconductor wafer positioning systems
  • Automated test equipment probe movement
Installation guidelines: Maintain 0.5mm minimum clearance between rod end and load during alignment. For vertical mounting, install with rod facing downward to prevent seal wear. Perform cushion adjustment under 0.3MPa pressure for optimal damping effect.
Maintenance: Relubricate every 3 million cycles using AirTAC AS-20 pneumatic oil. Replace cushion seals after 10,000km cumulative stroke travel. Avoid silicone-based lubricants to prevent seal degradation.
