About the Airtac SAID40 Double Rod Cylinder SAID40AX65S
The AirTAC SAID40X65-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 65 mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on extend and retract. This provides an equal output of 528 N in both directions at 0.5 MPa, ensuring symmetric speed and force for balanced automation tasks.
Equipped with a -S magnet, this model supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves. The rod is constructed from SUS420J2 stainless steel (option A) for enhanced corrosion resistance, and fluid supply is managed via PT tapered ports. The through-rod design allows mounting a secondary cam or position flag on the rear extension to drive auxiliary mechanisms.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX65S Is Used
Symmetric Force Transfer
Ideal for moving loads where identical push and pull momentum is required, preventing jerky transitions during direction changes on indexing conveyors.
Through-Rod Sensing
The rear rod extension drives an external cam or flag, operating a mechanical limit switch independently of the primary front-side work tool.
Anti-Rotation Slides
Twin rod guidance resists torsional twisting on lifting slides, maintaining precise vertical alignment for packaging and assembly tooling.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX65S the Right Cylinder?
Select this 40 mm bore when an application demands equal push and pull forces, which a single-rod SAI cannot provide due to its asymmetric piston areas. If your mechanism requires less force, stepping down to a 32 mm bore yields 345 N both ways; stepping up to a 50 mm bore provides 825 N. The SAID series utilizes a specific mounting subset—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR brackets found on single-rod variants.
As a standard double-acting cylinder, the SAID40X65-S relies on adjustable air cushions at both ends to decelerate the piston, but it does not hold position or lock the load when air pressure is lost. For dead-load holding without live pressure, consider a SAIL lock cylinder, a BSAID clamp-lock, or an external pilot-operated check valve. Dimensionally interchangeable per ISO 15552, it serves as a drop-in replacement for other standard profile double-rod cylinders.

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 SAID40AX65S FAQ
Because the rod occupies both sides of the piston, the effective area is equal 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 SAID40X65-S is dimensionally interchangeable per ISO 15552. It shares the standard mounting interface and utilizes the SAID accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), making it a drop-in replacement for equivalent profile cylinders.
