About the Airtac SAID100 Double Rod Cylinder SAID100AX290S
The AirTAC SAID100X290-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 290mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding equal force and speed in both directions. This cylinder generates 3681N of thrust each way at 0.5 MPa, rising to 5153N at 0.7 MPa.
Equipped with a magnet (-S) for position sensing, it supports AirTAC CMSE reed and DMSE electronic solid-state switches along the dual sensor grooves machined into the extruded aluminum barrel. The rod is constructed from SUS420J2 stainless steel (material code A) for enhanced corrosion resistance, and fluid connections use PT tapered threads sized at G1/2.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX290S Is Used
Symmetric Force Transfer
Drives heavy push-pull stations where the 3681N thrust must remain perfectly balanced in both directions without speed discrepancies.
Anti-Rotation Slides
Utilizes the twin-rod architecture to guide vertical lifting slides, preventing piston rotation and ensuring precise vertical load tracking.
Dual-Side Tooling Actuation
Mounts the primary workpiece on the front rod end and a rear limit flag or secondary cam on the opposite end to trigger DMSE sensors.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX290S the Right Cylinder?
Select this 100mm bore when an application demands symmetric thrust—such as 3681N both ways at 0.5 MPa—or when stepping up from a bore 80 unit (which provides 2268N). A double-rod design is preferred over a single-rod SAI when you need to mount a workpiece on one end and a cam, position flag, or secondary mechanism on the rear rod, providing superior anti-rotation guidance. For holding loads without live air pressure, note that the adjustable air cushions only decelerate the piston at stroke ends; you must use an external rod lock or a BSAID clamp-lock cylinder for secure position holding.
At a 290mm stroke, the unsupported rod length increases; for optimal bearing life and to prevent rod bending under side loads, incorporate an external guide rail. This dimensionally interchangeable ISO 15552 cylinder uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod variants.
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 SAID100AX290S FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It provides equal force in both directions: 3681N at 0.5 MPa, 5153N at 0.7 MPa, and 6626N at 0.9 MPa.
Yes, it shares the exact ISO 15552 mounting interface dimensions, making it a drop-in replacement for other standard ISO 15552 profile double-rod cylinders. Just ensure your mounting bracket uses the supported SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
