About the Airtac SAID40 Double Rod Cylinder SAID40BX130S
The AirTAC SAID40X130-S is a double-acting, double-rod ISO 15552 profile cylinder. Because a stainless steel SUS304 rod exits both end covers, the annular piston area is identical on extend and retract, yielding an equal 528 N of force in each direction at 0.5 MPa. This through-rod geometry is ideal when you need to drive a workpiece on one end while mounting a cam or position flag on the opposite end.
It includes a built-in magnet compatible with AirTAC CMSE reed and DMSE solid-state sensors, which seat neatly into the dual sensor grooves machined into the extruded aluminum barrel. PT tapered port threads are standard on this 40 mm bore, which uses a G1/4 air connection and adjustable air cushioning at both ends.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX130S Is Used
Symmetric Transfer
Drives a transfer arm on the front rod while using the rear rod to actuate a secondary mechanism, utilizing the equal 528 N extend and retract forces.
Anti-Rotation Slide
The twin SUS304 rods keep the load guided against rotation throughout the 130 mm stroke, preventing torsional deflection on precision slides.
Dual-End Sensing
Uses the integrated magnet with CMSE and DMSE sensors in the dual barrel grooves to track both end-of-stroke positions independently.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX130S the Right Cylinder?
Select this 40 mm bore double-rod actuator when your mechanism requires equal push and pull forces (528 N both ways at 0.5 MPa) or superior anti-rotation guidance compared to a single-rod SAI. If your application demands less force, the 32 mm bore offers 345 N; if you need more thrust, the 50 mm bore provides 825 N. The SAID mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants reserved for single-rod cylinders.
Because the rear rod protrudes from the back cover, ensure you leave adequate clearance for the 130 mm stroke. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If air pressure drops, the piston will drift. For position holding, consider an external rod lock or the SAIL/BSAID locking cylinder variants.

- ✓ 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 SAID40BX130S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the push and pull forces are equal. It generates 528 N in both directions at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
Yes, the SAID40X130-S is dimensionally interchangeable per ISO 15552 standards. It serves as a drop-in replacement for other ISO 15552 profile-type double-rod cylinders, using the same mounting interface and a G1/4 port.
