About the Airtac SAID40 Double Rod Cylinder SAID40AX15S
The AirTAC SAID40X15-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 15 mm short stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding 528 N of force each way at 0.5 MPa. The -S suffix denotes an integrated magnet compatible with AirTAC CMSE reed and DMSE solid-state sensors mounted in the dual side grooves.
This through-rod configuration is ideal for mounting the primary workpiece on one end and a position flag or secondary cam on the rear. It features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threading. As a true ISO 15552 extruded aluminum profile cylinder, it offers a dimensionally interchangeable drop-in replacement for other ISO 15552 double-rod units.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX15S Is Used
Symmetric Force Transfer
Ideal for mechanisms requiring identical 528 N push and pull forces at 0.5 MPa to shuttle parts back and forth without speed variations.
Anti-Rotation Slides
The twin-rod design keeps the load guided and prevents rotation better than a single rod, making it perfect for precision sliding fixtures.
Through-Rod Sensing
Mount the primary tool on the front rod and a position flag on the rear protrusion to trigger CMSE or DMSE sensors for dual-station actuation.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX15S the Right Cylinder?
Select this 40 mm bore when an application requires equal push and pull forces alongside twin-side guidance. If your mechanism needs less force, the 32 mm bore provides 345 N both ways at 0.5 MPa; step up to the 50 mm bore for 825 N. The SAID design provides superior anti-rotation characteristics compared to a single-rod SAI, allowing you to drive a second mechanism or rear-mounted sensor flag.
When ordering, verify your bore, stroke, PT port, mounting accessory, and the -S magnet. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that this cylinder relies on adjustable air cushioning at both ends to decelerate the piston; it does not hold a load or position when air pressure is lost. For dead-stop holding, consider an external rod lock or the SAIL/BSAID locking variants.
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 SAID40AX15S FAQ
Because the double-rod design occupies area on both sides of the piston, the effective area is identical in both directions. It provides 528 N of force both extending and retracting at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, the SAID is an extruded aluminum profile cylinder with standard ISO 15552 mounting interface dimensions, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders.
