Airtac SAID40 Double Rod Cylinder SAID40AX65
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40AX65 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 65mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID40 Double Rod Cylinder SAID40AX65
The AirTAC SAID40X65 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and a 65mm non-standard stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 528N of force in each direction at 0.5 MPa. This through-rod design is ideal for applications requiring dual-side guidance or anti-rotation control.
This specific configuration uses SUS420J2 stainless steel rods (material code A) for enhanced corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Note that the 65mm stroke is a made-to-order length, meaning nonstandard_stroke is true.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX65 Is Used
Symmetric Force Transfer
Provides equal 528N push and pull forces for transferring parts between two parallel workstations without speed variations between stroke directions.
Anti-Rotation Slides
The twin rods exiting both ends keep the load guided and prevent rotational torque from skewing precision sliding mechanisms.
Through-Rod Sensing
Mount a cam or position flag on the rear rod to trigger external sensors, while the front rod drives the primary tool.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX65 the Right Cylinder?
Choose this double-rod SAID40X65 over a single-rod SAI when your mechanism requires a rear rod for mounting a cam, position flag, or secondary tool, or when symmetric load guidance is needed to prevent rotation. If you need higher force, stepping up to the 50mm bore yields 825N both ways at 0.5 MPa. If less force is acceptable, the 32mm bore provides 345N.
This model is dimensionally interchangeable per ISO 15552, offering a drop-in replacement for other ISO 15552 double-rod cylinders. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod variants. Remember that a plain SAID does not hold a load when air is lost; the piston will drift without live pressure, so use a SAIL lock or external rod lock for position holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAID40AX65 FAQ
Because the double-rod design has the same effective piston area on both sides, it provides an equal force of 528N in both extend and retract directions at 0.5 MPa, and 739N at 0.7 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. It supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting styles, but omits FB, CA, CB, and CR brackets.
