This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X220S, 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 SID80X220S
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X220S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 220mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X220S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X220S
The AirTAC SID80X220S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This means both faces use the rod-side area, so push and pull force are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. It features a 80mm bore, 25mm piston rod, M20x1.5 rod-end thread, 36mm adjustable air cushions at each end, and a fixed G3/8 air port. This SID model is discontinued and end-of-life; the direct replacement is the SAID80X220S, sharing the same ISO 15552 mounting interface, bore, stroke, force, and port.
The SAI replacement uses an upgraded piston seal with two Y-shaped one-way elements for long life and low start-up pressure. A double-rod design prevents rod rotation and lets the back rod carry a sensor cam or drive a second tool. The -S suffix denotes a built-in piston magnet for legacy 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 pilot-operated check valve for held loads.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID80X220S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously using both rod ends, ensuring perfectly synchronized cutting cycles without requiring a separate cylinder.
Anti-Rotation Transfer Gate
Uses the dual-rod architecture to prevent rod rotation during actuation, maintaining precise alignment of a transfer gate mechanism on a high-speed packaging line.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X220S with the SAID80X220S
To replace the discontinued SID80X220S, install the direct replacement SAID80X220S, which matches the ISO 15552 interface, G3/8 port, 220mm stroke, and 25mm rod. Size both ways by checking the equal push/pull force against neighbor bores: the 63mm bore yields 1402 N @0.5 MPa, while the 100mm bore yields 3681 N @0.5 MPa. Choose a double-rod cylinder when you need anti-rotation stability or a back rod to drive a second tool. Mounting options include Basic, FA, LB, and TC. The -S magnet supports legacy CS1-B/DS1-B switches. For stroke lengths of 300mm or greater, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X220S
- ✓ 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 SID80X220S FAQ
Yes, the AirTAC SID80X220S is discontinued and end-of-life. The direct replacement is the SAID80X220S. It shares the same ISO 15552 mounting interface, 80mm bore, 220mm stroke, G3/8 port, and equal both-ways force. The SAI replacement also adds an upgraded piston seal for longer life.
Because it is a double-rod cylinder, force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. It operates at 0.15-1.0 MPa (proof 1.5 MPa) with a speed of 30-800 mm/s. The bore is 80mm with a 25mm rod, M20x1.5 thread, and 36mm adjustable air cushions.
