This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X80CA, 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 SI160 Standard Cylinder SI160X80CA
The AirTAC Airtac SI160 Standard Cylinder SI160X80CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X80CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X80CA
The AirTAC SI160X80CA is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke, CA clevis mount, and a 160 mm bore delivering 10053 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI160X80CA, a direct upgrade retaining the exact G3/4 port, M36x2 rod thread, and 50 mm cushions. Because this specific SKU lacks the -S magnet, it cannot accept position sensors.
The SAI replacement introduces an upgraded piston seal featuring two Y-shaped one-way elements for lower start-up pressure and extended life. For heavy loads, note that a standard cylinder drifts without live air; the cushion only decelerates. Use the SAIL or BSAI lock variants, or an external pilot check valve, to hold loads.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X80CA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X80CA Is Used
Heavy Stamping Press
Drives large heavy-duty stamping and forming dies requiring high force over an 80 mm stroke, utilizing the 160 mm bore to deliver 10053 N at 0.5 MPa.
Large Clamp Fixture
Secures oversized metal castings or heavy components during machining via the CA clevis mount, absorbing side loads while clamping with 9425 N pull force.
Replacing the Airtac SI160 Standard Cylinder SI160X80CA with the SAI160X80CA
To replace the SI160X80CA, order the SAI160X80CA and confirm the CA clevis mounting, 160 mm bore, 80 mm stroke, and G3/4 port. Specify the thread standard (PT, G, or NPT) and rod material (carbon, SUS420J2, or SUS304). Since this SKU has no -S magnet, it cannot support switches; if sensing is needed, select an SAI model with the magnet option and current AirTAC switches. Sizing both ways: this bore yields 10053 N push at 0.5 MPa, while a 200 mm bore provides 15708 N; a 125 mm bore offers 6136 N. For load holding on air loss, add an external rod lock or pilot check valve, as the standard cushion only decelerates. The SAIL or BSAI lock variants are ideal for safety holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X80CA
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
