Description
1. ISO 15552 (formerly ISO 6431) standard double rod adjustable cylinder.
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
Installation note:
Always align cylinder axis with motion direction within ±0.5° tolerance.
Lubricate rods monthly with ISO VG32 hydraulic oil. For vertical mounting,
install a speed controller to prevent piston slam at stroke ends.
Avoid side load exceeding 150N.
Use rod-end bearings when connecting to pivoting mechanisms.
Maximum allowable misalignment: 0.2mm per 100mm stroke.

High-precision dual rod cylinder designed for applications requiring exceptional rigidity and alignment stability. Features twin 12mm hardened rods that eliminate rotational movement, with external stroke adjustment screws allowing ±5mm fine-tuning. The reinforced mounting ears withstand 2x higher lateral loads compared to single rod cylinders.
Typical Applications:
- Precision fixture positioning in CNC machining centers
- Vertical lifting mechanisms for robotic arms
- Glass panel transfer systems requiring parallel motion
- Press-fit operations in automotive assembly lines
- Optical component alignment stages
Installation note:
Always align cylinder axis with motion direction within ±0.5° tolerance.
Lubricate rods monthly with ISO VG32 hydraulic oil. For vertical mounting,
install a speed controller to prevent piston slam at stroke ends.
Avoid side load exceeding 150N.
Use rod-end bearings when connecting to pivoting mechanisms.
Maximum allowable misalignment: 0.2mm per 100mm stroke.
