This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X100TC, 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 SI80X100TC
The AirTAC SI80 Standard Air Cylinder SI80X100TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X100TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X100TC
The AirTAC SI80X100TC is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 100 mm stroke, delivering 2513 N push and 2268 N pull at 0.5 MPa via a G3/8 port. AirTAC replaced this EOL unit with the SAI80X100TC, a direct upgrade retaining the exact ISO 15552 mounting interface, TC trunnion mount, M20x1.5 rod thread, and 36 mm cushions.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet, so it cannot accept CS1-B or DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80X100TC carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SI80X100TC Is Used
Pallet Diversion
Actuates heavy lane diverters on packaging lines, using the 2513 N push force to reliably shift loaded pallets onto secondary conveyors.
Clamp Ejection
Provides the robust thrust needed to eject stacked cardboard cartons from compression clamps in automated sorting hubs.
Press Ejection
Mounts via TC trunnion to swing heavy lower dies or eject finished stamped parts from mid-sized mechanical presses.
Replacing the Airtac SI80 Standard Air Cylinder SI80X100TC with the SAI80X100TC
To replace the SI80X100TC, order the SAI80X100TC. Confirm the ISO 15552 TC trunnion interface, 80 mm bore, 100 mm stroke, G3/8 port (PT/G/NPT thread options), and M20x1.5 rod. Since this SKU has no -S magnet, it cannot support position sensing; if switches are needed, specify a magnet on the SAI order. Sizing both ways: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants. The SAI family also offers the SAIF integrated valve (bores 32-100) and Viton H seals for 0-150 C heat.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X100TC
- ✓ 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 SI80X100TC FAQ
Yes, the SI80X100TC is discontinued. The direct replacement is the SAI80X100TC. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 100 mm stroke, G3/8 port, TC trunnion mount, and output force, so it fits existing fixtures directly.
The 80 mm bore features a G3/8 air port and provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. It operates at 30-800 mm/s with a 36 mm adjustable air cushion at both ends.
