This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X600S, 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 SID200X600S
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID200X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X600S
The AirTAC SID200X600S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. This bore 200 mm model has a 40 mm rod, M36x2 thread, G3/4 port, and 50 mm adjustable cushions. The SID line is discontinued; the direct replacement is the SAID200X600S, which reuses the same ISO 15552 mounting interface, bore, stroke, and porting.
The SAI upgrade features an improved two Y-shaped one-way piston seal for low start-up pressure and long life. The double-rod design prevents rotation and lets the rear rod carry a sensor cam. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; current AirTAC switches are used on the SAI replacement.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID200X600S Is Used
Twin-Tool Press Drive
Drives two opposing forming tools simultaneously with equal 21110 N @0.7 MPa push and pull force, using the second rod to carry an external cam for stroke confirmation.
Anti-Rotation Transfer Unit
Moves heavy pallets along a 600 mm stroke without rotational drift, relying on the double-rod geometry to maintain precise alignment under high side-loading.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X600S with the SAID200X600S
To replace the discontinued SID200X600S, specify the SAID200X600S, which is a direct swap retaining the 600 mm stroke, G3/4 port, and ISO 15552 mounting footprint (Basic, FA, LB, TC). Because force is equal both ways, you can size both directions identically; if 21110 N @0.7 MPa is insufficient, evaluate the next bore up, or step down if excess force exists. A double rod is right when you need anti-rotation, a rear sensor cam, or two driven tools. The -S magnet supports position sensing. For the 600 mm stroke, use external guides to prevent rod bending and side loads. The air cushion only decelerates near stroke end; it does not hold loads on air loss, so use an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X600S
- ✓ 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 SID200X600S FAQ
Yes, the SID200X600S is discontinued. The direct replacement is the SAID200X600S, which shares the same 200 mm bore, 600 mm stroke, G3/4 port, and ISO 15552 mounting interface. The SAI family also adds upgraded piston seals and SAIL or BSAI lock variants.
Because it is a double-rod cylinder, force is equal both ways: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. The bore 200 mm configuration uses a 40 mm rod, M36x2 thread, G3/4 air port, 50 mm adjustable cushions, and operates at 30-500 mm/s.
