This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X80TC, 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 SI100X80TC
The AirTAC Airtac SI100 Standard Cylinder SI100X80TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 80mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X80TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X80TC
The AirTAC SI100X80TC is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke, delivering a push force of 3927 N at 0.5 MPa. It features a G1/2 port, a 25 mm piston rod, and a TC trunnion mount. The direct replacement is the SAI100X80TC, which matches the original bore, stroke, force, port, and mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this specific SKU lacks a magnet (-S) and cannot accept a sensor.

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 SI100X80TC Is Used
Heavy Press Operations
Drives 3927 N of push force at 0.5 MPa for clamping and pressing heavy sheet metal assemblies in automated fabrication cells.
Replacing the Airtac SI100 Standard Cylinder SI100X80TC with the SAI100X80TC
To replace the SI100X80TC, order the SAI100X80TC. Confirm the ISO 15552 TC trunnion mounting interface, the G1/2 port, and the 80 mm stroke. Because this non-magnetic SKU lacks a slot for CS1-B/DS1-B sensors, you cannot add position sensing. If you need higher force, the neighboring 125 mm bore offers 6136 N push at 0.5 MPa; if you need less, the 80 mm bore provides 2513 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X80TC
- ✓ 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 SI100X80TC FAQ
Yes, the SI100X80TC is discontinued. The direct replacement is the AirTAC SAI100X80TC. It is dimensionally interchangeable per ISO 15552, matching the 100 mm bore, 80 mm stroke, G1/2 port, and TC trunnion mount.
The 100 mm bore delivers a push of 3927 N and pull of 3681 N at 0.5 MPa. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical max force is 801 kgf at 1.0 MPa, with an operating speed of 30-800 mm/s.
