About the Airtac SAID40 Double Rod Cylinder SAID40AX475
The AirTAC SAID40X475 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 16 mm rod exiting both end covers. Because the piston area is equal on both sides, it generates 528 N of force in both extend and retract directions at 0.5 MPa. This symmetric output is ideal for applications requiring consistent speed and thrust both ways.
This configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount position switches independently on either end to track the dual rod movements.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX475 Is Used
Symmetric Force Transfer
Drives a transfer shuttle that pushes a part forward and pulls an empty fixture back with identical 528 N thrust, ensuring balanced momentum on a 475 mm slide.
Anti-Rotation Slides
The twin 16 mm rods keep the workpiece guided against rotation without needing external linear bearings, maintaining precise alignment over the long stroke.
Rear-Rod Sensing
Mounts a cam or target flag on the protruding rear rod end to trigger external sensors, keeping the primary front workspace clear of obstruction.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX475 the Right Cylinder?
Select this 40 mm bore when an application demands exactly 528 N of thrust in both directions, stepping down from the 63 mm bore (1402 N) for a lighter, faster cycle. A twin-rod design is chosen over a single-rod SAI when you need to drive a tool on the front while mounting a cam or position flag on the rear rod. Note that a plain double-rod cylinder drifts if air pressure is lost; use a BSAID clamp-lock or external pilot-operated check valve if the load must be held.
With a 475 mm stroke, the unsupported rod length increases the risk of side-load bending. Use an external guide rail to support the load and prevent excessive wear on the rod bearings. As a dimensionally interchangeable ISO 15552 cylinder, it drops in for other double-rod profile cylinders using the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces.
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 SAID40AX475 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It outputs 528 N in both the extend and retract directions at 0.5 MPa, and 739 N both ways at 0.7 MPa.
Yes, it shares the exact ISO 15552 mounting interface dimensions. It is compatible with the Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessory sets, though it omits the FB, CA, CB, and CR mounts used on single-rod variants.
