About the Airtac SAID100 Double Rod Cylinder SAID100AX155
The AirTAC SAID100X155 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 155mm stroke. A single piston drives a rod out of both end covers, meaning the annulus area is identical on extend and retract. Consequently, it generates an equal 3681N of force in both directions at 0.5MPa, eliminating the speed and force asymmetry found in single-rod variants.
This unit is equipped with a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting, and the PT tapered port threads ensure a reliable, progressive sealing connection. The rear rod extension is specifically useful for mounting a secondary cam, position flag, or driving a secondary mechanism.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX155 Is Used
Symmetric Transfer
Ideal for transferring workpieces across a conveyor with equal push and pull velocity, preventing jerky movements caused by differential piston areas.
Twin-Station Actuation
Drive two separate mechanisms simultaneously from one cylinder, using the front rod for the primary workpiece and the rear rod to trigger a secondary process.
Anti-Rotation Slides
The dual-rod configuration provides superior guidance and resists torsional deflection, keeping external linear slides perfectly aligned under offset loads.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX155 the Right Cylinder?
Choose this 100mm bore when an application demands symmetric thrust and dual-side guidance, stepping up from a 80mm bore (2268N at 0.5MPa) or down from a 125mm bore (5734N at 0.5MPa) to match your exact load. The twin-rod design is selected over a single-rod SAI when the mechanism requires anti-rotation stability or a rear-mounted position flag. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If position holding without live air pressure is required, consider a SAIL or BSAID cylinder. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Specify the 155mm stroke, PT port, and the appropriate mounting accessory from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAID100AX155 FAQ
Because the rod exits both ends, the effective piston area is the same in both directions. It delivers 3681N of force both extending and retracting at 0.5MPa, and 5153N at 0.7MPa.
Yes, it is a profile cylinder dimensionally interchangeable per ISO 15552. However, the SAID series uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR brackets found on single-rod variants.
