About the Airtac SAID40 Double Rod Cylinder SAID40AX110S
The AirTAC SAID40X110-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and a 110mm stroke. Because a rod exits both end covers, the annulus area is identical on both sides, yielding exactly 528 N of force at 0.5 MPa in both extend and retract directions. This 110mm stroke is a non-standard made-to-order length, meaning the overall body spans a custom dimension that requires extra rear clearance for the protruding rod.
This unit includes a magnet for position sensing and uses a SUS420J2 stainless steel rod for enhanced corrosion resistance. The PT tapered port threads match the G1/4 standard for this bore. You can mount AirTAC CMSE reed or DMSE solid-state switches directly into the extruded aluminum barrel grooves on both sides to track the piston across its 30-800 mm/s operating range.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX110S Is Used
Symmetric Force Transfer
Ideal for transferring delicate webs or films where the 528 N both-ways force prevents tension variation between the extend and retract strokes.
Dual-Station Actuation
Drive a primary workpiece on the front rod while using the rear protruding rod end to trip a DMSE solid-state sensor or actuate a secondary mechanism.
Anti-Rotation Slides
The twin-rod design naturally resists torsional twist, providing stable guidance for vertical lifting slides that would bind with a single-rod cylinder.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX110S the Right Cylinder?
Choose this double-rod configuration when your mechanism demands equal push and pull forces, or when you need to drive a secondary cam and position flag from the rear rod end without relying on a single-rod SAI cylinder. If your application requires slightly less force, stepping down to a 32mm bore provides 345 N each way at 0.5 MPa; if you need more thrust, a 50mm bore offers 825 N both directions. Because this is a non-standard 110mm stroke, expect made-to-order lead times.
This cylinder uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits the FB, CA, CB, and CR brackets found on single-rod variants. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 double-rod cylinders. Remember that the adjustable air cushions only decelerate the piston near stroke end; a plain SAID does not hold a load if air pressure drops. For position holding without live pressure, consider an external rod lock or the BSAID clamp-lock series.

- ✓ 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 SAID40AX110S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. It provides 528 N of force at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa for both extend and retract strokes.
Yes. It is an extruded aluminum ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses PT (G1/4) ports and the standard SAID mounting interface.
