About the Airtac SAID40 Double Rod Cylinder SAID40AX105
The AirTAC SAID40X105 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and a 105mm non-standard made-to-order stroke. Because a rod exits both end covers, the effective piston annulus area is identical in both directions, yielding an equal extend and retract force of 528N at 0.5 MPa. This symmetric output is ideal for applications requiring consistent push and pull dynamics.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. Note that the rear rod protrudes during operation, requiring additional clearance behind the cylinder to prevent mechanical interference.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX105 Is Used
Symmetric Transfer Unit
Provides equal 528N push and pull force at 0.5 MPa for seamless dual-direction product transfer without speed discrepancies.
Anti-Rotation Slide
The twin-rod architecture prevents piston rotation, securely guiding precision slides and external workloads along the stroke.
Dual-Station Actuation
Mount the primary workpiece on the front rod and a secondary cam or position flag on the rear rod to drive two synchronized stations.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX105 the Right Cylinder?
Select this 40mm bore when an application demands equal 528N force both ways, stepping down from the 63mm bore (1402N at 0.5 MPa) for lighter loads, or up from the 32mm bore (345N). The twin-rod design is chosen over a single-rod SAI when the mechanism requires dual-side guidance, anti-rotation stability, or a rear rod to mount a secondary cam and position flag. Because the 105mm stroke is non-standard, expect a made-to-order lead time.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing a reduced mounting accessory set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Since no -S magnet is specified, position sensing requires external limits. Finally, note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If the system loses air pressure, the piston will drift—use an external rod lock or pilot-operated check valve for position holding.

- ✓ 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 SAID40AX105 FAQ
Because the double-rod design subtracts the rod area on both sides, the extend and retract forces are equal. It provides 528N of force both ways at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa.
Yes, the SAID40X105 is dimensionally interchangeable per ISO 15552 standards. It uses the same profile footprint and a mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, allowing it to serve as a drop-in replacement for other ISO 15552 double-rod cylinders.
