The MD20X20H features a unique mechanical locking mechanism that holds position without continuous air supply. Its triple-position control (via separate air ports) enables precise intermediate stopping, with 0.02mm repeat positioning accuracy. The anodized barrel resists industrial chemicals, while the chrome-plated rod includes a scraper seal for contamination prevention.
- PCB assembly positioning fixtures
- Automated tool changers in CNC machines
- Pharmaceutical capsule filling stations
- Glass panel alignment systems
- Robotic welding jig locking
Installation note:
Locking pressure must be 1.5× operating pressure. Use M5 2m³/h flow valves for position switching.
Avoid side loads exceeding 15N. Lubricate rod monthly in high-cycle applications (>500,000 cycles/yr).
