Airtac SAID40 Double Rod Cylinder SAID40AX60
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40AX60 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 60mm 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 SAID40AX60
The AirTAC SAID40X60 is a double-acting, double-rod ISO 15552 profile cylinder. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 528 N of force in both directions at 0.5 MPa. The 16 mm rods are made of SUS420J2 stainless steel (code A) for superior corrosion resistance, and the fluid ports use a PT tapered thread type.
This through-rod design allows you to mount the primary workpiece on one end and attach a position flag, cam, or secondary mechanism on the rear rod end. The extruded aluminum barrel features sensor grooves on both sides, and while no magnet is specified for this configuration, the adjustable air cushions at both ends ensure smooth deceleration at speeds up to 800 mm/s.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX60 Is Used
Symmetric Transfer
Drives a transfer mechanism where the 528 N extend and retract forces must be perfectly equal, ensuring consistent acceleration in both directions without pressure compensation.
Anti-Rotation Slide
The twin 16 mm rods guide the load against torsional rotation, making it ideal for precision sliding tasks where a single rod would allow the tooling to twist.
Rear-Rod Sensing
Mounts the primary tool on the front rod while using the rear rod end to trip an external mechanical limit switch or drive a secondary mechanism.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX60 the Right Cylinder?
Choose this 40 mm bore when a 32 mm bore (345 N at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (1402 N at 0.5 MPa) is physically too large. The twin-rod architecture is selected over a single-rod SAI when an application demands dual-side guidance, better resistance to torsional rotation, or a rear-rod output for secondary actuation. It is dimensionally interchangeable with other ISO 15552 double-rod cylinders.
Remember that a plain SAID does not hold its position if air pressure is lost or the valve is centered; the piston will drift. For load-holding requirements, consider an AirTAC SAIL (air-released lock), BSAID (clamp-lock), or an external rod lock. The mounting accessory set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles found on single-rod variants.
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 SAID40AX60 FAQ
Because the double-rod design has the same annulus area on both sides, the push and pull forces are equal. It generates 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa in both directions.
Yes, the SAID40X60 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mountings.
