This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X200H, 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 SI80 Standard Air Cylinder SI80X200H
The AirTAC SI80 Standard Air Cylinder SI80X200H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X200H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X200H
The AirTAC SI80X200H is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, delivering 2513 N push force at 0.5 MPa through its G3/8 port. Because the SI line is end-of-life, you should order the direct replacement: the SAI80X200H. It matches the original 80 mm bore, 200 mm stroke, M20x1.5 rod thread and mounting interface, dropping straight into existing fixtures.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This specific SKU lacks a magnet, so it cannot accept a CS1-B or DS1-B sensor. The H designation indicates a Viton seal, raising the operating temperature ceiling to 150 C.

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

Where the Airtac SI80 Standard Air Cylinder SI80X200H Is Used
Hot Stamp Presses
Handles 200 mm actuation in heated environments up to 150 C, using the Viton H seal to maintain integrity while applying 2513 N of clamping force.
High-Temp Diverters
Pushes heavy product streams at 0.5 MPa safely, leveraging the 1508 N working load capacity to deflect items without risking mechanical failure.
Molten Metal Gates
Operates 200 mm stroke gating mechanisms near thermal zones, relying on the G3/8 port and ISO 15552 profile to deliver consistent 3518 N thrust at 0.7 MPa.
Replacing the Airtac SI80 Standard Air Cylinder SI80X200H with the SAI80X200H
To replace the SI80X200H, order the SAI80X200H, confirming the ISO 15552 interface, 80 mm bore, 200 mm stroke, G3/8 port and your existing mounting accessory. If you need position sensing, this no-magnet version cannot take a switch, so select an SAI80X200HS instead. To size both ways, the 80 mm bore yields 2513 N push at 0.5 MPa; if you need less force, the 63 mm bore offers 1559 N, while the 100 mm bore provides 3927 N for heavier loads. Remember that a standard cylinder drifts on air loss because the 36 mm adjustable cushion only decelerates near stroke end. For load holding, use an external pilot check valve, a rod lock, or the SAIL/BSAI lock variants. The SAI family also adds the SAIF variant with a built-in 4M valve for bores 32-100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X200H
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80X200H FAQ
Yes, the SI80X200H is discontinued. The direct replacement is the SAI80X200H. It is dimensionally interchangeable per ISO 15552, keeping the same 80 mm bore, 200 mm stroke, G3/8 port and mounting footprint.
It features a G3/8 air port and provides 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa it pushes 3518 N, and 4523 N at 0.9 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa.
