About the Airtac SAID40 Double Rod Cylinder SAID40AX90
The AirTAC SAID40X90 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 90 mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides, yielding an equal extend and retract force of 528 N at 0.5 MPa. This symmetric output is essential for mechanisms requiring consistent push and pull dynamics.
Equipped with a SUS420J2 stainless steel rod (option A), this variant provides enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this specific unit ships without a magnet. Its PT tapered port threads ensure a robust, leak-free pneumatic connection.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX90 Is Used
Symmetric Transfer
Drives a workpiece forward and retracts it with identical 528 N force, ensuring smooth and predictable motion for automated material handling.
Anti-Rotation Slides
The twin-rod configuration naturally resists torsional twisting, providing stable guidance for vertical lifting slides without external rails.
Rear-rod Sensing
Allows a mechanical cam or physical flag to be mounted on the rear rod end to trigger external mechanical limit switches independently.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX90 the Right Cylinder?
Select this 40 mm bore when an application demands 528 N of symmetric force in both directions, or step down to a 32 mm bore (345 N) for lighter loads. A double-rod design is preferred over a single-rod SAI when you need to mount a cam or position flag on the rear rod, or when twin-side guidance is required to prevent rotation. Keep in mind that a plain SAID does not hold its position if air pressure is lost; use a SAIL or BSAID cylinder if mid-stroke locking is required.
For drop-in compatibility, this cylinder matches standard ISO 15552 mounting dimensions. It supports a reduced set of accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2) and operates at speeds between 30 and 800 mm/s. Since the stroke is 90 mm, side-load stress on the rod bearing is minimal, but external guidance is always recommended for heavy radial loads.

- ✓ 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 SAID40AX90 FAQ
The SAID40X90 provides an equal force of 528 N in both the extend and retract directions at 0.5 MPa. At 0.7 MPa, the both-way force is 739 N.
Yes, the SAID40X90 is dimensionally interchangeable per ISO 15552. It shares standard mounting dimensions but uses a specific accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and requires PT port threading.
