- Material ejection systems in injection molding
- Conveyor gate actuators
- Printing press paper feed mechanisms
- Automated welding positioners
Maintenance tip:
Lubricate air supply with 1-3 drops of oil per 1m³ airflow monthly.
Avoid side-load forces exceeding 20N·m. For vertical mounting,
use spring-side port as exhaust to prevent piston creep.
