About the Airtac SAID40 Double Rod Cylinder SAID40X100
The AirTAC SAID40X100 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a carbon steel rod exits both end covers, the effective piston area is identical in each direction, yielding exactly 528 N of force on both extend and retract at 0.5 MPa. This through-rod architecture is ideal when you need to drive a workpiece from the front while mounting a cam or position flag at the rear.
The extruded aluminum barrel integrates sensor grooves on both sides for flexible switch placement. Without the -S magnet option, this unit relies on external mechanical signaling, though the grooves remain ready for future upgrades. Adjustable air cushions at both ends absorb end-of-stroke impact, and the PT tapered port threads ensure a tight pneumatic seal.

Where the Airtac SAID40 Double Rod Cylinder SAID40X100 Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull force, ensuring consistent acceleration regardless of travel direction.
Anti-Rotation Slide
The twin-rod layout prevents mechanical twisting during vertical lifts, maintaining precise linear guidance without external rails.
Rear-Cam Actuation
Mounts the primary tool on the front rod while utilizing the rear rod extension to trigger external limit valves or mechanical stops.
Is the Airtac SAID40 Double Rod Cylinder SAID40X100 the Right Cylinder?
Select this 40mm bore when an application demands equal force and speed in both travel directions, offering a balanced 528 N output that sits neatly between the lighter 32mm (345 N) and the heavier 50mm (825 N) variants. The twin-rod design provides superior anti-rotation resistance compared to a single-rod SAI cylinder, making it the preferred choice for guided slides and dual-station mechanisms. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
For dimensionally interchangeable ISO 15552 drop-in replacements, match the 40mm bore, 100mm stroke, and G1/4 port size. Remember that the adjustable air cushion only decelerates the piston near stroke end; it does not lock the load. If air pressure is lost, the cylinder will drift, requiring an external pilot-operated check valve or a SAIL locking cylinder for true 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 SAID40X100 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is identical in both directions. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
Yes, the SAID40X100 is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing setups by matching the 40mm bore, 100mm stroke, and G1/4 port, but note it uses the SAID mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
