This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X160TC, 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 SI80X160TC
The AirTAC SI80 Standard Air Cylinder SI80X160TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X160TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X160TC
The AirTAC SI80X160TC is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel and adjustable air cushions. It delivers 2513 N push force at 0.5 MPa through an 80 mm bore. The direct replacement is the SAI80X160TC, which retains the same TC trunnion mount, G3/8 port, and 160 mm stroke.
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, so it cannot accept CS1-B/DS1-B sensors. The SAI family also adds SAIL, SAIF, and BSAI lock variants absent in the SI line.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAI80X160TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI80 Standard Air Cylinder SI80X160TC Is Used
Pallet Diversion
Uses the 160 mm stroke to push heavy pallets onto a parallel conveyor line, relying on the 2513 N push force at 0.5 MPa for reliable lateral transfer.
Clamp Actuation
Secures large metal castings during CNC machining. The TC trunnion handles the pivot stress while the 80 mm bore provides rigid, high-force clamping.
Stacker Elevation
Lifts goods vertically in automated storage racks.
Replacing the Airtac SI80 Standard Air Cylinder SI80X160TC with the SAI80X160TC
To replace the SI80X160TC, order the SAI80X160TC. It is dimensionally interchangeable per the ISO 15552 mounting interface, matching the 80 mm bore, 160 mm stroke, 2518 N @0.5 MPa force, G3/8 port, and TC trunnion mount. Because this legacy SKU has no -S magnet, it cannot support position sensing; if you need switches, specify a magnet on the SAI order and use current AirTAC sensors. If sizing alternatives, 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 consider the SAIL or BSAI lock variants, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X160TC
- ✓ 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 SI80X160TC FAQ
Yes, the SI80X160TC is discontinued. The direct replacement is the SAI80X160TC. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 80 mm bore, 160 mm stroke, G3/8 port, force, and TC trunnion mount.
The 80 mm bore uses a G3/8 air port. It generates 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.
