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:
Lubricate with ISO VG32 hydraulic oil before initial use. Avoid angular misalignment exceeding 0.5° during mounting.
For vertical installations, use the auxiliary support brackets (sold separately) to prevent piston rod deflection.

A high-rigidity dual-axis cylinder with synchronized motion control, featuring chromium-plated piston rods and aluminum alloy end caps. The T-slot design on both axes allows direct mounting of fixtures/tools. Special anti-rotation mechanism maintains parallel rod alignment under heavy side loads. Includes shock-absorbing bumpers and auto-lubrication maintenance ports.
Typical Applications:
- Precision alignment in CNC fixture systems
- Simultaneous clamping in automotive welding jigs
- Vertical Z-axis positioning in 3D printing/pick-and-place machines
- Parallel gripper actuation in packaging lines
- Material transfer in cleanroom environments
Installation note:
Lubricate with ISO VG32 hydraulic oil before initial use. Avoid angular misalignment exceeding 0.5° during mounting.
For vertical installations, use the auxiliary support brackets (sold separately) to prevent piston rod deflection.
