About the Airtac SAID40 Double Rod Cylinder SAID40AX160
The AirTAC SAID40X160 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 160mm stroke. Because a piston rod exits both end covers, the annular area is identical on extend and retract, yielding a balanced 528N of force in both directions at 0.5MPa (739N at 0.7MPa).
This unit uses a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable air cushions at both ends provide 30mm of end-of-stroke deceleration. Note that the rear rod protrudes, requiring extra clearance in your machine layout.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX160 Is Used
Symmetric Transfer
Drives a shuttle mechanism where equal force and speed in both directions prevent stalling on the return stroke.
Anti-Rotation Slide
Uses the twin rods to guide a heavy vertical slide, preventing torsional twist without external linear bearings.
Rear-Cam Actuation
Mounts the primary tool on the front rod end while using the rear rod end to trip a mechanical limit switch.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX160 the Right Cylinder?
Select this 40mm bore when an application requires equal push and pull forces, which differs from a single-rod SAI cylinder that has a larger extend force. If your mechanism needs less force, step down to the 32mm bore (345N both ways at 0.5MPa); for heavier loads, step up to the 50mm bore (825N both ways). The PT (tapered) port thread and G1/4 air supply match standard ISO 15552 plumbing.
Choose the twin-rod design to mount a workpiece on the front and a position flag or cam on the rear rod, providing dual-side guidance and anti-rotation control. Remember that a plain SAID does not hold position if air pressure drops; use a SAIL lock or BSAID clamp-lock cylinder for fail-safe load holding. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAID40AX160 FAQ
Because the rod occupies both sides of the piston, the extend and retract forces are equal. It generates 528N at 0.5MPa, 739N at 0.7MPa, and 950N at 0.9MPa in both directions.
Yes, the SAID40X160 is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 double-rod cylinders, matching the 40mm bore, 160mm stroke, and G1/4 port.
