The SAU40X140 medium-duty cylinder features precision honed tubing and double piston seals for leak-free operation. Its modular design allows easy integration with magnetic switches (e.g., SME-8 series) and adjustable cushioning prevents end-impact damage. Requires ISO 8573-1:2010 Class 3 lubricated or non-lubricated air (40μm filtration recommended).
- Automated assembly line clamping mechanisms
- CNC machine tool door interlocks
- Plastic injection molding ejector systems
- Printing press paper feed actuators
- Automotive welding fixture positioning
Installation guidelines:
Maximum side load ≤15% of thrust rating. For vertical mounting,
use rod-down orientation. Lubricate through air supply port
(ISO VG32 hydraulic oil recommended) if using non-lubricated system.
