Airtac SAID40 Double Rod Cylinder SAID40AX1000
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40AX1000 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 1000mm 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 SAID40AX1000
The AirTAC SAID40X1000 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 1000mm stroke. Because a piston 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 symmetric output is essential for applications requiring perfectly matched push and pull dynamics.
This variant is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Note that a 1000mm stroke is the maximum standard length for this bore, meaning the overall physical length is substantial and requires significant rear-rod clearance.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX1000 Is Used
Symmetric Force Transfer
Provides identical 528N push and pull forces for reciprocating mechanisms that require perfectly balanced kinetic energy in both directions.
Anti-Rotation Slides
The twin-rod design resists torsional twist better than a single rod, keeping long 1000mm travel loads guided and preventing binding.
Rear-Rod Sensing Flag
Mount a position flag or cam on the protruding rear rod to trigger DMSE electronic sensors without interfering with the primary workpiece.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX1000 the Right Cylinder?
Select this 40mm bore double-rod actuator when your mechanism demands equal 528N force both ways, anti-rotation guidance, or a rear-rod cam. If your application needs less force, stepping down to the 32mm bore offers 345N each way, while moving up to the 50mm bore provides 825N. The G1/4 PT tapered port and M12x1.25 rod thread are fixed for this bore size. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
At 1000mm of travel, the unsupported rod length is highly susceptible to side-load bending and rod-bearing wear; an external guide rail is strongly recommended to prevent premature seal failure. Additionally, the adjustable air cushions at both ends only decelerate the piston near stroke end and do not lock the load. If your system loses air pressure, the cylinder will drift, requiring an external pilot-operated check valve or a BSAID clamp-lock cylinder 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 SAID40AX1000 FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It delivers 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa on both extend and retract strokes.
It is dimensionally interchangeable per ISO 15552 with other profile-type double-rod cylinders. However, it does not hold position if air is lost; the cushions only decelerate the piston. For load holding, consider an external rod lock or a BSAID cylinder.
