This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X900S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SID Series Double-Rod Cylinder SID100X900S
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X900S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 900mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X900S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X900S
The AirTAC SID100X900S is a double-acting, double-rod ISO 15552 cylinder featuring a 100mm bore and 900mm stroke. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. This model is discontinued; the direct replacement is the SAID100X900S, which retains the G1/2 port, M20x1.5 rod thread, and 36mm adjustable cushions. The SAI upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life.
A key double-rod benefit is anti-rotation, allowing a back rod to carry a sensor cam or drive two tools simultaneously while reusing your ISO 15552 mounting interface. Note that a plain cylinder does not hold loads on air loss; the cushion only decelerates. For held loads, use an external rod lock or SAIL/BSAI variant.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID100X900S Is Used
Dual-Tool Machining Station
Drives two opposing machining heads with equal 5153N @0.7MPa force both ways, ensuring balanced material removal without single-rod push disparity.
Anti-Rotation Transfer Gate
Uses the twin-rod architecture to prevent mechanical twist during 900mm travel, guiding pallets smoothly without binding.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X900S with the SAID100X900S
To replace the discontinued SID100X900S, specify the SAID100X900S, which matches the 100mm bore, 900mm stroke, G1/2 port, and equal-both-ways force. Size both ways by checking neighbor bores: the 80mm bore yields 2268N @0.5MPa, and the 125mm bore yields 5734N @0.5MPa. A double rod is right when you need anti-rotation or equal push/pull force. Mounting options include Basic, FA, LB, and TC. The -S suffix means a magnet is present for CS1-B/DS1-B switches. For the 900mm stroke, add external guides to prevent rod-bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X900S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SID Series Double-Rod Cylinder SID100X900S FAQ
Yes, the SID100X900S is discontinued. The direct replacement is the SAID100X900S, sharing the same ISO 15552 interface, 100mm bore, 900mm stroke, G1/2 port, and mounting.
Force is equal both ways: 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. The bore uses a G1/2 air port, a 25mm rod, M20x1.5 rod thread, and 36mm adjustable cushions. Speed is 30-800mm/s.
