This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X800TC, 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 SI100 Standard Cylinder SI100X800TC
The AirTAC Airtac SI100 Standard Cylinder SI100X800TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 800mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X800TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X800TC
The AirTAC SI100X800TC is a discontinued double-acting ISO 15552 profile cylinder with an 800 mm stroke and TC trunnion mount. Delivering 3927 N push force at 0.5 MPa through a G1/2 port, it is replaced by the SAI100X800TC. This direct successor shares the exact bore, stroke, force, port and mounting dimensions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnetic SKU cannot accept a sensor; the legacy SI used CS1-B/DS1-B switches. For high heat, Viton H seals raise the temperature range to 0-150 C.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X800TC Is Used
Pallet Transfer Lines
Drives heavy pallets over the full 800 mm stroke, relying on the 3927 N push force at 0.5 MPa to shift loads between machining stations.
Automated Warehousing
Actuates large lifting gates or diverter arms where the TC trunnion mount accommodates angular alignment during long 800 mm traverses.
Heavy Press Ejection
Ejects dense finished parts from press beds, utilizing the 801 kgf maximum theoretical force capability for stubborn jam clears.
Replacing the Airtac SI100 Standard Cylinder SI100X800TC with the SAI100X800TC
To replace the SI100X800TC, order the SAI100X800TC. Verify the ISO 15552 TC trunnion interface, 100 mm bore, 800 mm stroke, G1/2 port (PT/G/NPT thread options) and M20x1.5 rod thread. Because this stroke is 800 mm, add external guides to prevent rod bending and side-load damage. Sizing both ways: a neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while a 125 mm bore yields 6136 N. This non-magnetic version cannot host a sensor. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X800TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X800TC FAQ
Yes, the SI100X800TC is discontinued. The direct replacement is the SAI100X800TC. It is dimensionally interchangeable per ISO 15552, retaining the same TC mount, 100 mm bore, 800 mm stroke, G1/2 port and output force, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure.
The bore features a G1/2 air port and an M20x1.5 rod thread. Force output is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
