About the Airtac SAID40 Double Rod Cylinder SAID40AX95S
The AirTAC SAID40X95-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and a 95mm made-to-order stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 528 N of force each way at 0.5 MPa (739 N at 0.7 MPa). This symmetric output is ideal for mechanisms requiring equal push and pull dynamics.
Equipped with a magnet for position sensing, this variant works seamlessly with AirTAC CMSE reed and DMSE solid-state switches mounted in the dual-side sensor grooves. It incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The twin-rod architecture allows mounting a primary workpiece on one end and a cam or limit flag on the opposing rear rod end.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX95S Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull thrust, ensuring consistent cycle times regardless of travel direction.
Anti-Rotation Slide
The twin-rod layout prevents mechanical twisting under offset loads, guiding the carriage smoothly without external guide rails.
Dual-Station Actuation
Mounts the primary tool on the front rod end and a secondary cam or position flag on the rear protruding rod to trigger external sensors.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX95S the Right Cylinder?
Select this 40mm double-rod cylinder when your mechanism demands equal force and speed in both travel directions, plus superior anti-rotation guidance compared to a single-rod SAI. The 95mm stroke is a non-standard made-to-order length, providing exact kinematics for custom machinery. If your application requires less force, the 32mm bore offers 345 N both ways at 0.5 MPa; if you need more thrust, the 50mm bore provides 825 N.
Ensure you specify the correct mounting accessories from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (note that FB, CA, CB, and CR mounts are exclusive to single-rod SAI models). Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If air pressure drops, the piston will drift unless paired with an external rod lock or a SAIL/BSAID locking cylinder.
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 SAID40AX95S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It delivers 528 N of force both extending and retracting at 0.5 MPa, and 739 N both ways at 0.7 MPa.
Yes, the SAID40X95-S is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other standard ISO 15552 double-rod cylinders, utilizing a PT G1/4 port and a 16mm rod.
