About the Airtac SAID40 Double Rod Cylinder SAID40AX10S
The AirTAC SAID40X10-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding an equal 528 N of force in both extend and retract directions at 0.5 MPa. This through-rod geometry provides superior anti-rotation guidance and allows a secondary mechanism to be driven from the rear.
Equipped with a magnetic piston (-S), this variant supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side barrel grooves. It features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The adjustable air cushions at both ends decelerate the piston near stroke end, though they do not function as a locking mechanism.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX10S Is Used
Symmetric Force Transfer
Provides exactly 528 N of thrust and pull at 0.5 MPa, ensuring perfectly balanced movement for transfer shuttles that require identical dynamics in both directions.
Anti-Rotation Guidance
The dual-rod design resists torsional twisting under offset loads, making it ideal for precision pick-and-place units where rigid linear guidance is critical.
Dual-Side Actuation
Drive a primary workpiece from the front rod while using the rear protrusion to trigger a CMSE or DMSE sensor flag, streamlining machine timing logic.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX10S the Right Cylinder?
Select this 40 mm bore cylinder when an application demands perfectly matched push and pull forces, stepping up from a 32 mm bore (345 N both ways) or down from a 50 mm bore (825 N both ways). The twin-rod architecture is ideal for anti-rotation slides, twin-station actuation, or mounting a rear position flag, offering distinct advantages over a single-rod SAI. Remember that a plain SAID does not hold position if air pressure is lost; for load-holding requirements, consider an external pilot-operated check valve or the BSAID clamp-lock series.
For a drop-in replacement, match the 40 mm bore, 10 mm stroke, PT port thread, and desired mounting accessory. The SAID mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found on single-rod variants. As a true ISO 15552 extruded aluminum profile cylinder, it is dimensionally interchangeable with other ISO 15552 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 SAID40AX10S FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It generates an equal force of 528 N in both extend and retract directions at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, the SAID40X10-S is an extruded aluminum profile cylinder built to ISO 15552 mounting dimensions. It is dimensionally interchangeable with other ISO 15552 double-rod cylinders, provided you match the 40 mm bore, 10 mm stroke, and PT port threads.
