Description
1. ISO15552 (formerly ISO6431) compliant standard cylinder
2. Piston sealing features dual-locked Y-type axial sealing structure with dust scraping capability, delivering extended service life and low friction resistance;
3. Aluminum tube with cross-shaped reinforcement and anodized tie rods for enhanced corrosion resistance;
4. Optimized cushion adjustment system with stable stroke control;
5. Multiple bore sizes and mounting accessories available for flexible configuration.
Category: Standard Cylinders | Brand: Airtac | Series: SI63
Installation note:
Ensure proper alignment of piston rod (max lateral load ≤15% of thrust force).
For vertical mounting, use rod-down orientation to prevent seal wear.
Lubricate every 3 months in continuous operation (1-2 drops ISO VG32 oil per port).
