- Steel coil clamping mechanisms
- Injection molding machine ejectors
- Paper roll positioning systems
- Shipbuilding fixture actuators
Installation note:
For horizontal mounting >500mm stroke, use dual rod support brackets.
Maintain 0.5-1mm/m alignment tolerance during installation. Lubricate rod weekly
with ISO VG32 hydraulic oil in high-cycle applications (>500k cycles/year).
