This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X100, 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 SID100X100
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X100
The AirTAC SID100X100 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, making the push and pull force equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This SKU is discontinued and is replaced by the SAID100X100. The SAID direct uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life, while keeping the exact G1/2 port, M20x1.5 rod thread, and 3681 N equal-both-ways force. This non-magnetic SKU cannot take a sensor.
Because both faces use the rod-side area, the back rod can drive a second tool or carry a sensor cam on adjacent setups. The 36 mm adjustable air cushions only decelerate near stroke end; they do not hold loads on air loss, 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 | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAID100X100 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SID Series Double-Rod Cylinder SID100X100 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously from one piston, utilizing the equal both-ways force to ensure perfectly synchronized cutting cycles.
Anti-Rotation Transfer Gate
Uses the dual-rod architecture to prevent mechanical twist during rapid part diversion on a 100 mm bore conveyor line, maintaining precise alignment.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X100 with the SAID100X100
To replace the discontinued SID100X100, drop in the SAID100X100: it matches the ISO 15552 mounting interface, 100 mm bore, 100 mm stroke, G1/2 port, and 3681 N equal-both-ways force. Size both directions by checking neighbouring bores (80 mm yields 2268 N, 125 mm yields 5734 N @0.5 MPa) to ensure the equal push/pull force fits your load. A double rod is right when you need anti-rotation stability or must drive two tools from one piston. Reuse FA, LB, or TC mounts. This SKU lacks the -S magnet, so it cannot support sensing. For stroke lengths >=300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X100
- ✓ 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 SID100X100 FAQ
Yes, the SID100X100 is discontinued. The direct replacement is the SAID100X100, which shares the same ISO 15552 interface, 100 mm bore, 100 mm stroke, G1/2 port, and 3681 N equal-both-ways force, but adds an upgraded piston seal.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The fixed air port is G1/2, the rod thread is M20x1.5, and speed is 30-800 mm/s. It cannot hold loads without live air.
