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:
Ensure parallel alignment of both piston rods during mounting. Use precision level
for base installation (tolerance ≤0.1mm/m). Lubricate with ISO VG32 hydraulic oil
before initial operation. Stroke adjustment should be performed at 0.3MPa or lower.

High-precision dual-rod cylinder with mechanical stroke adjustment mechanism. Features chrome-plated piston rods with wear-resistant guide bushes for stable linear motion. The modular design allows ±3mm stroke adjustment via rotating end caps, making it ideal for precise positioning tasks. Requires ISO 8573-1 air quality standard.
Typical Applications:
- Precision fixture positioning in CNC machining centers
- Clamping mechanisms in automated assembly lines
- Material handling systems requiring dual-point control
- Packaging machine stopper adjustments
- Glass panel alignment in electronics manufacturing
Installation note:
Ensure parallel alignment of both piston rods during mounting. Use precision level
for base installation (tolerance ≤0.1mm/m). Lubricate with ISO VG32 hydraulic oil
before initial operation. Stroke adjustment should be performed at 0.3MPa or lower.
Stroke Adjustment:
- Loosen the lock nut (M6) on cylinder end cap
- Rotate adjustment screw clockwise to shorten stroke (max. 3mm reduction)
- Counter-clockwise rotation extends stroke (max. 3mm extension)
- Re-tighten lock nut to 1.2N·m torque after adjustment
