About the Airtac SAID40 Double Rod Cylinder SAID40X5S
The AirTAC SAID40X5-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a 5 mm stroke and an -S magnet for position sensing. Because the through-rod occupies both sides of the piston, the annulus area is identical in extend and retract, yielding an equal 528 N of force both ways at 0.5 MPa. The carbon steel rod exits both end covers, allowing you to mount the primary workpiece on one end and a cam, second tool, or DMSE electronic sensor flag on the rear.
This short-stroke unit features a G1/4 PT port and adjustable air cushions at both ends to decelerate the piston near stroke limits. It shares the extruded aluminum barrel and dual-side sensor grooves of the standard SAI series, making it dimensionally interchangeable per ISO 15552 mounting dimensions.

Where the Airtac SAID40 Double Rod Cylinder SAID40X5S Is Used
Symmetric Force Transfer
Ideal for short-stroke pushing and pulling where equal 528 N force in both directions ensures balanced, stable load handling without speed discrepancies.
Dual-Side Tool Actuation
The through-rod design allows mounting a primary workpiece on the front and a secondary cam or guide on the rear rod end for synchronized tooling.
Anti-Rotation Slides
Twin-rod guidance prevents piston rotation during the 5 mm stroke, maintaining strict alignment for precision clamping and gripping tasks.
Is the Airtac SAID40 Double Rod Cylinder SAID40X5S the Right Cylinder?
Choose this 40 mm bore when an application requires symmetric force and dual-side guidance rather than the single-rod action of a standard SAI. It generates 528 N each way at 0.5 MPa; if your mechanism needs less force, step down to the 32 mm bore (345 N), or step up to the 50 mm bore (1154 N at 0.7 MPa) for heavier transfer tasks. The -S magnet enables precise end-of-stroke detection using AirTAC CMSE reed or DMSE solid-state switches.
A plain double-rod cylinder does not hold its position or load if air pressure is lost or the valve is centered, as the piston will drift. The adjustable cushion only decelerates the piston near stroke end and acts as no lock; for fail-safe holding, consider an external rod lock or the SAIL series. This SAID model supports the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR accessories found on single-rod 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 SAID40X5S FAQ
The double-rod design provides equal force in both directions. It delivers 528 N 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 dimensionally interchangeable with ISO 15552 profile cylinders. It supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting styles, but omits the FB, CA, CB, and CR brackets.
