Description
1. ISO15552 (formerly ISO6431) Standard Pneumatic Cylinder
2. Piston features bidirectional Y-seal structure with cushioning function, offering extended service life and low friction resistance;
3. Aluminum barrel with cruciform reinforcement and black-anodized piston rod for enhanced corrosion resistance;
4. Precision machined cylinder surface ensures smooth operation;
5. Multiple cylinder specifications and mounting accessories available for flexible configurations.
Category: Standard Cylinders | Brand: AIRTAC | Series: SI125
Installation note:
Maintain 0.1mm/m alignment tolerance during mounting. For vertical installations,
use rod-down orientation to prevent piston drift. Lubricate through air supply
(1-2 drops/m³ air) unless using oil-free seals.
