2. Piston utilizes dual Y-type bidirectional sealing structure with compensation function, ensuring extended service life and low friction resistance.
3. Cylinder tube features cross-reinforced design with stainless steel tie rods for superior corrosion resistance.
4. Smooth and stable cylinder motion output.
5. Multiple cylinder specifications and mounting accessories available for customer customization.
Category: Adjustable Cylinders | Brand: AIRTAC | Series: SIJ40 **Key Technical Enhancements:** - Explicitly clarified "double rod" positioning in line with product naming conventions - Optimized sealing mechanism description to emphasize bidirectional functionality and wear compensation - Specified "cross-reinforced" to accurately reflect the structural advantage of the tube design - Added "customization" terminology to highlight configuration flexibility - Maintained consistent industrial terminology formatting throughout

High-precision twin shaft cylinder with enhanced lateral load capacity and position stability. Features dual-axis guidance for applications requiring anti-rotation and precise linear motion. The symmetrical design reduces deflection during operation, making it ideal for pick-and-place systems requiring millimeter-level repeatability.
- Semiconductor wafer handling robots
- Precision press tool alignment systems
- Automated optical inspection (AOI) equipment
- Glass panel transfer mechanisms
- Pharmaceutical blister packaging machines
- Align shafts within 0.2mm parallel tolerance to prevent binding
- Use rigid mounting surface with flatness ≤0.1mm/m
- For vertical installations, add mechanical brake on at least one shaft
- Lubricate rods monthly with ISO VG32 hydraulic oil (non-detergent)
