Classification: Standard Cylinders | Brand: AirTAC | Series: SAUJ80
1. Enterprise-standardized cylinder design;
2. Asymmetric bidirectional sealing structure for piston with integrated oil reservoir, achieving compact dimensions;
3. Cross-ribbed aluminum tube construction (rodless design) with enhanced corrosion resistance. External surface features sensor mounting grooves for simplified installation;
4. Compact length design compared to ISO 15662 standard cylinders within the SAU bore series;
5. Progressive cushioning adjustment mechanism for smooth stroke termination;
6. Full compatibility with SC series cylinder mounting accessories;
7. High-temperature resistant sealing materials enable operational range: 0~150°C.
Key innovations: Optimized space efficiency through length reduction vs ISO standards, dual-purpose lubrication retention system, and cross-reinforced aluminum body for structural integrity.
