The hard-anodized barrel provides exceptional corrosion resistance in humid environments. Includes built-in auto-adjust cushioning system that reduces end-impact noise by 15dB compared to standard models.
- Automated packaging line pusher mechanisms
- Plastic injection molding machine ejectors
- CNC machine tool clamping systems
- Automotive welding fixture positioning
- Food processing conveyor gate controls
Installation note:
For vertical mounting applications exceeding 45° angle, install an air pressure holding device.
Lubricate through air supply (ISO VG32 recommended) when operating below 0.3 MPa.
Maintain 0.5mm clearance between magnetic sensor and cylinder axis.
