The SI40X342 features a hard-anodized aluminum barrel and chrome-plated piston rod for enhanced corrosion resistance. Its dual adjustable pneumatic cushioning minimizes end-impact noise while maintaining precise stroke control. The cylinder incorporates a dual-seal design with wiper ring to prevent contamination ingress. Designed for 5,000km service life under standard operating conditions.
- Automated assembly line clamping mechanisms
- Packaging machine ejection systems
- CNC machine tool door actuators
- Industrial press feeding devices
- Automotive welding fixture positioning
Installation note:
For vertical mounting, use rod-down orientation to prevent seal wear.
Maintain 0.3-1.0MPa lubrication pressure if using oil mist lubrication.
Allow 5mm minimum clearance around cylinder body for heat dissipation.
- Relubricate every 3,000km stroke or 6 months
- Inspect rod surface roughness (Ra ≤0.4μm)
- Replace cushion seals at 20 million cycles
