A high-rigidity pneumatic actuator with chromium-plated piston rod and corrosion-resistant construction. Features dual adjustable rubber buffers to minimize end-impact noise. The cylinder tube undergoes hard oxidation treatment for enhanced wear resistance, making it suitable for high-cycle applications. Requires 5-50μm filtered lubricated air (ISO 8573-1 class 4-4-3).
- Automated assembly line clamping mechanisms
- Packaging machine ejector systems
- CNC machine tool chip conveyors
- Printing press paper feed units
- Automotive welding fixture positioning
Installation note:
Lubricate rod weekly with ISO VG32 hydraulic oil. Avoid side load exceeding 30N.
For vertical mounting, use counterbalance valves (sold separately). Allow 15mm
clearance for rod extension.
