About the Airtac SAID100 Double Rod Cylinder SAID100AX400
The AirTAC SAID100X400 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because the piston rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal force of 3681 N in both directions at 0.5 MPa. This makes it ideal for mechanisms requiring balanced push and pull dynamics.
This specific unit features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and ships with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches on either end to track the through-rod position.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX400 Is Used
Symmetric Force Transfer
Drives heavy shuttle mechanisms requiring identical push and pull thrust, utilizing the 3681 N bidirectional output to move loads evenly without force imbalance.
Anti-Rotation Slides
Guides heavy vertical lifting slides using the twin-rod architecture to prevent mechanical twisting and maintain precise linear tracking under offset loads.
Rear-rod Cam Actuation
Mounts the primary workpiece on the front rod while using the rear protrusion to trigger external DMSE electronic sensors or operate a secondary mechanism.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX400 the Right Cylinder?
Select this 100mm bore when an application demands high bidirectional force (3681 N at 0.5 MPa) that a smaller bore like the SAID80X400 cannot provide. The twin-rod design is chosen over a single-rod SAI when the mechanism requires dual-side guidance to prevent rotation, or when a rear rod end is needed to drive a secondary cam. To replace an existing ISO 15552 cylinder, match the 400mm stroke, PT G1/2 port, and mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Note that a plain SAID does not hold position if air pressure is lost; use a SAIL or BSAID lock variant if mid-stroke holding is required. With a 400mm stroke, the unsupported rod length increases; always use an external guide to prevent rod-bearing bending under heavy side loads.
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 SAID100 Double Rod Cylinder SAID100AX400 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It provides an equal force of 3681 N in both extend and retract directions at 0.5 MPa, and 5153 N at 0.7 MPa.
Yes, the SAID100X400 is dimensionally interchangeable per ISO 15552. It shares standard mounting dimensions and uses the same G1/2 port, but note that SAID supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set only.
