This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X800TC, 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 SI80X800TC
The AirTAC SI80 Standard Air Cylinder SI80X800TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X800TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X800TC
The AirTAC SI80X800TC is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 800 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X800TC, retaining the exact TC trunnion mounting, stroke, and output force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. This no-magnet SKU cannot take a sensor, unlike legacy CS1-B/DS1-B setups.

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 SAI80X800TC 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 SI80X800TC Is Used
Long-Stroke Diversion
Pushes heavy pallets laterally across a 800 mm conveyor belt lane using the 2513 N thrust at 0.5 MPa.
Automated Press Ejection
Ejects formed parts from a press bed, relying on the 36 mm adjustable air cushions to decelerate at stroke end.
Replacing the Airtac SI80 Standard Air Cylinder SI80X800TC with the SAI80X800TC
To replace the SI80X800TC, order the SAI80X800TC ensuring the ISO 15552 TC trunnion interface, 80 mm bore, 800 mm stroke, and G3/8 port match. If sizing down, the 63 mm bore yields 1559 N [email protected]; if sizing up, the 100 mm bore yields 3927 N. Because this is an 800 mm stroke, use an external guide to prevent rod bending and side-load wear. The air cushion only decelerates; it does not hold load. For load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants. Note: this no-S SKU cannot accept a magnetic sensor.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X800TC
- ✓ 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 SI80X800TC FAQ
Yes, the SI80X800TC is discontinued. The direct replacement is the SAI80X800TC. It is dimensionally interchangeable per ISO 15552, maintaining the same TC trunnion mount, 80 mm bore, 800 mm stroke, G3/8 port, and output force.
The G3/8 port feeds a 25 mm rod. Force ratings are: push 2513 N and pull 2268 N at 0.5 MPa; push 3518 N at 0.7 MPa; push 4523 N at 0.9 MPa; and a theoretical max of 513 kgf at 1.0 MPa. Speed is 30-800 mm/s.
