- Printing press paper feed systems
- CNC machine tool actuation
- Food packaging vertical lift systems
- Automotive welding fixture positioning
Installation note:
For optimal performance, align cylinder axis within 0.2mm parallel tolerance.
Use flexible couplings when connecting to guided mechanisms. Lubricate rod weekly
in high-cycle applications (>500 cycles/day).
