About the Airtac SAID100 Double Rod Cylinder SAID100X125S
The AirTAC SAID100X125-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 125mm stroke. Because the piston rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 3681N of force in each direction at 0.5 MPa. The standard carbon steel rods provide robust load support, while the integrated magnet (-S) enables direct mounting of CMSE reed or DMSE electronic sensors along the dual side grooves.
This through-rod design is ideal for applications requiring symmetrical power and dual-side guidance. You can mount the primary workpiece on one end and a cam or position flag on the rear rod to trigger external sensors without interfering with the main operation. The cylinder uses adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAID100 Double Rod Cylinder SAID100X125S Is Used
Symmetric Force Transfer
Drives a transfer carriage with equal 3681N push and pull force at 0.5 MPa, ensuring consistent momentum regardless of travel direction.
Twin-Station Actuation
Mounts a forming tool on the front rod end and a secondary ejector cam on the rear protruding rod to sequence two operations from one cylinder.
Anti-Rotation Slides
Uses the dual through-rod ends to guide a heavy vertical slide, preventing torsional twist and maintaining precise linear tracking.
Is the Airtac SAID100 Double Rod Cylinder SAID100X125S the Right Cylinder?
Choose this 100mm bore when you need higher equal bidirectional force than a neighbouring 80mm unit (which provides 2268N at 0.5 MPa), but do not require the massive output of the 160mm class. The double-rod architecture is selected over a single-rod SAI when the mechanism demands anti-rotation stability, twin-station actuation, or rear-rod sensing. Since the stroke is 125mm, side-load stress on the rod bearing is moderate, though an external guide is still recommended for heavy off-center loads.
This model features a PT tapered G1/2 port and a built-in magnet for CMSE/DMSE switches. Note that a plain SAID does not hold its position if air pressure is lost; for dead-end holding, consider an external pilot-operated check valve. It is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mountings.

- ✓ 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 SAID100X125S FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers 3681N of force in both extend and retract directions at 0.5 MPa, and 5153N at 0.7 MPa.
Yes, the SAID100X125-S is dimensionally interchangeable per ISO 15552. It shares the standard mounting footprint and uses the same Basic, FA, LB, and TC accessories, though it omits FB, CA, CB, and CR mounts.
