This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X700S, 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 SID100X700S
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X700S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X700S
The AirTAC SID100X700S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Both faces use the rod-side area, so push and pull force are equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The bore is 100 mm, the port is G1/2, the rod thread is M20x1.5, and adjustable air cushions are 36 mm at each end. The direct replacement is the SAID100X700S, which retains the exact ISO 15552 mounting interface, bore, stroke, and force.
The SAI replacement uses an upgraded piston seal with two Y-shaped one-way elements for long life and low start-up pressure. The -S suffix on this legacy unit means it has a built-in piston magnet for CS1-B/DS1-B switches. A plain cylinder does not hold its load on air loss; the cushion only decelerates near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

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 SID100X700S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads from one piston, utilizing the equal both-ways force to maintain perfectly synchronized cutting cycles.
Anti-Rotation Transfer Unit
Uses the dual-rod architecture to prevent rotation during a 700 mm transfer stroke, ensuring precise part handoff without external guides.
Symmetric Push-Pull Divertor
Employs the back rod to carry a sensor cam while the front rod actuates a diverting arm, keeping force identical in both directions.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X700S with the SAID100X700S
To replace the discontinued SID100X700S, use the SAID100X700S direct: same 100 mm bore, 700 mm stroke, G1/2 port, and ISO 15552 mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2). Size both ways using the equal force ratings: 3681 N @0.5 MPa, 5153 N @0.7 MPa, 6626 N @0.9 MPa. If you need less force, the 80 mm bore neighbor offers 2268 N @0.5 MPa; for more, the 125 mm bore gives 5734 N @0.5 MPa. A double rod is right when you need anti-rotation stability or must drive two tools from one piston. Because the 700 mm stroke is long, add external guides to prevent rod bending under side loads. The -S magnet enables legacy CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X700S
- ✓ 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 SID100X700S FAQ
Yes, the AirTAC SID100X700S is discontinued. The direct replacement is the SAID100X700S. It shares the same ISO 15552 mounting interface, 100 mm bore, 700 mm stroke, G1/2 port, and equal both-ways force. The SAI family also adds an upgraded piston seal and new lock variants.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The air port is G1/2, rod thread is M20x1.5, and speed is 30-800 mm/s. The cushion only decelerates; it does not hold loads on air loss.
