- Automotive welding fixture positioning
- Steel coil handling equipment
- Plastic injection molding machine gates
- Paper converting machinery actuators
Installation note:
Allow 1.5× bore size clearance (≥120mm) for rod extension.
Use alignment couplers when stroke accuracy exceeds ±0.5mm/m.
Lubricate rod weekly in high particulate environments.
