Airtac SAID100 Double Rod Cylinder SAID100AX40
The AirTAC Airtac SAID100 Double Rod Cylinder SAID100AX40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 40mm stroke, G1/2 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 SAID100 Double Rod Cylinder SAID100AX40
The AirTAC SAID100X40 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 40mm stroke. Because the twin rods occupy both sides of the piston, the effective annulus area is identical in each direction, yielding an equal extend and retract force of 3681N at 0.5 MPa. This symmetric output is ideal for mechanisms requiring perfectly balanced push and pull dynamics.
This variant is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and PT tapered port threads. A rod extends from both end covers, allowing you to mount the primary workpiece on the front while attaching a rear cam or position flag to trigger external sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX40 Is Used
Symmetric Force Transfer
Drives heavy transfer shuttles where the 3681N push and pull forces must remain perfectly identical to maintain consistent momentum in both travel directions.
Anti-Rotation Guiding
Lifts and positions heavy assemblies using the twin-rod structure to prevent mechanical twisting, eliminating the need for external linear guide rails.
Rear-Cam Actuation
Utilizes the protruding rear rod end to physically trip external limit valves or mechanical flags while the front rod performs the primary workstroke.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX40 the Right Cylinder?
Select this 100mm bore model when an application demands substantial symmetric thrust—delivering 3681N both ways—that a smaller 80mm bore (2268N at 0.5 MPa) cannot provide, or step up from this if you need the 160mm bore's 9425N capacity. The double-rod architecture is chosen over a single-rod SAI when the load requires anti-rotation guidance, dual-side actuation, or rear-rod position sensing. For drop-in replacements, verify the 40mm stroke, G1/2 port, and mounting accessory.
When specifying mounting hardware, note that SAID supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, deliberately omitting the FB, CA, CB, and CR styles used only on single-rod variants. Since this model lacks the -S magnet option, it cannot host internal CMSE reed or DMSE electronic sensors; external limit switches must be used instead. Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load if air pressure drops. For dead-load holding, consider an external pilot-operated check valve or the BSAID clamp-lock series.
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 SAID100 Double Rod Cylinder SAID100AX40 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides an equal force of 3681N at 0.5 MPa, 5153N at 0.7 MPa, and 6626N at 0.9 MPa for both extension and retraction.
It is dimensionally interchangeable per ISO 15552, but the SAID uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not support FB, CA, CB, or CR brackets due to the rear rod protrusion.
