- Automotive assembly line clamping units
- Palletizing robot end-effector drives
- Injection molding machine core pullers
- Steel mill roller positioning mechanisms
Installation note:
Allow 20mm minimum clearance around cylinder body for heat dissipation.
Use flexible couplings for stroke >500mm applications. Lubricate rod weekly
in high-cycle (>500,000 cycles/year) operations.
- Max side load: ≤15% of theoretical thrust
