About the Airtac SAID40 Double Rod Cylinder SAID40AX130
The AirTAC SAID40X130 is a double-acting, double-rod ISO 15552 profile cylinder. Because a rod exits both ends, the annulus area is identical on extend and retract, giving an equal 528 N of force in both directions at 0.5 MPa. The SUS420J2 stainless steel rods provide good corrosion resistance and surface hardness for demanding environments.
This through-rod design allows mounting a workpiece on the front and a position flag or cam on the rear. The extruded aluminum barrel features sensor grooves on both sides. It uses a PT G1/4 port and adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX130 Is Used
Symmetric Transfer
Drives a workpiece from one end while using the rear rod for a synchronized secondary operation, ensuring equal push and pull dynamics.
Anti-Rotation Slide
The twin-rod configuration prevents piston rotation, providing stable guidance for precision lifting and pressing tools.
Rear Cam Sensing
Mounts a position flag or cam on the protruding rear rod to trigger external sensors without interfering with the primary work area.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX130 the Right Cylinder?
Choose this 40 mm bore when you need symmetric force and speed both ways, or require anti-rotation guidance for a load. If your application needs higher thrust, step up to the 50 mm bore which yields 825 N each way at 0.5 MPa. If less force is acceptable, the 32 mm bore provides 345 N both directions.
A double-rod cylinder is selected over a single-rod SAI when you need to drive a secondary mechanism from the rear or maintain precise dual-side guiding. Remember that the adjustable cushions only decelerate the piston near stroke end; they do not hold the load. If air pressure is lost, the piston will drift. For position holding, consider an external pilot-operated check valve or the BSAID clamp-lock variant. This model is dimensionally interchangeable per ISO 15552.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID40 Double Rod Cylinder SAID40AX130 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers an equal force of 528 N in both extend and retract directions at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, the SAID40X130 is dimensionally interchangeable with other ISO 15552 profile cylinders. You can use it as a drop-in replacement by matching the 40 mm bore, 130 mm stroke, G1/4 port, and mounting accessories.
