Airtac SAID40 Double Rod Cylinder SAID40AX130S
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40AX130S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 130mm 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 SAID40AX130S
The AirTAC SAID40X130-S is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a rod out of both end covers, yielding equal effective areas on extend and retract. This symmetry means you get 528 N of force in both directions at 0.5 MPa, preventing the speed and force differential found in single-rod units.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The -S suffix indicates an integrated magnet for position sensing, compatible with AirTAC CMSE reed switches and DMSE solid-state sensors mounted in the dual-side barrel grooves. It uses PT tapered port threads and adjustable air cushions at both ends (30 mm cushion stroke) to decelerate the load near stroke end.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX130S Is Used
Symmetric Force Transfer
Transfers loads with identical 528 N push and pull forces at 0.5 MPa, ensuring consistent motion dynamics without differential speed shifts.
Anti-Rotation Guidance
Uses the twin rods exiting both covers to keep the workpiece guided against rotation, eliminating the need for bulky external guide rails.
Dual-Side Actuation
Mounts the primary tool on the front rod and a secondary cam or position flag on the rear rod to trigger AirTAC CMSE or DMSE sensors simultaneously.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX130S the Right Cylinder?
Choose this 40 mm bore double-rod cylinder when an application demands equal push and pull forces (528 N at 0.5 MPa) or requires anti-rotation guidance via twin rod ends. If you need less force, the 32 mm bore provides 345 N both ways; if your application requires more, step up to the 50 mm bore for 825 N.
The through-rod design allows mounting a workpiece on the front rod and a cam, position flag, or secondary mechanism on the rear rod. Remember that the adjustable cushion only decelerates the piston; it does not hold the load. If air pressure drops, the cylinder drifts, so use an external lock or pilot-operated check valve for position holding. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (FB, CA, CB, and CR are omitted on SAID).
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 SAID40AX130S FAQ
Because the double-rod design has the same annulus area on both sides, it provides 528 N of force in both extend and retract directions at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, the SAID40X130-S is a profile cylinder dimensionally interchangeable per ISO 15552. It shares the standard mounting interface and uses PT tapered G1/4 ports, though it omits the FB, CA, CB, and CR mounting styles found on single-rod variants.
