High-precision industrial cylinder engineered for heavy-duty linear motion applications requiring extended stroke lengths. Features corrosion-resistant construction with dual adjustable air cushions for smooth deceleration. Integrated wear-resistant guide rings ensure stable operation under side load conditions. Requires 40μm filtered lubricated air (ISO 8573-1 class 4).
- Automated palletizing systems
- Plastic injection molding ejectors
- Automotive assembly line positioning
- Packaging machine compression units
- Textile machinery tension control
Installation note:
Ensure proper alignment using alignment couplers when stroke exceeds 500mm.
For vertical mounting, install lock nuts on piston rod threads.
Lubricate through air supply (ISO VG32 equivalent oil mist) at 1 drop/3m³.
