- Steel mill material handling systems
- Plastic injection molding machine ejectors
- Paper processing equipment actuators
- Food packaging machine vertical lifts (non-contact areas)
Installation note:
Maintain 0.05-0.1mm clearance between magnetic sensor and cylinder body.
For vertical mounting, install with piston rod facing downward to prevent
uneven wear. Lubricate every 2,000km of cumulative stroke movement.
