This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X80, 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 SI160X80
The AirTAC Airtac SI160 Standard Cylinder SI160X80 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 SAI160X80, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X80
The AirTAC SI160X80 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke. Built for heavy-duty tasks, it delivers 10053 N of push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI160X80, a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, and output force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI160X80 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI160X80 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 SI160X80 Is Used
Heavy Stamp Pressing
Drives large metal forming and stamping dies requiring 10053 N of push force at 0.5 MPa.
Pallet Diverting
Actuates robust routing gates and heavy-load diverters in high-throughput distribution centers.
Mold Clamping
Secures substantial injection molds and industrial castings during automated manufacturing cycles.
Replacing the Airtac SI160 Standard Cylinder SI160X80 with the SAI160X80
To replace the SI160X80, order the SAI160X80 and confirm your ISO 15552 mounting accessories (LB, FA, CA, TC), G3/4 port threads, and M36x2 rod end. This 160 mm bore yields 10053 N push at 0.5 MPa; if less force is needed, an 80 mm bore provides 2513 N, whereas a 200 mm bore offers 15708 N. Note that a plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding. The SAI family also adds SAIL and BSAI lock variants for integrated braking.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X80
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X80 FAQ
Yes, the AirTAC SI160X80 is discontinued. The direct replacement is the SAI160X80, which shares the same ISO 15552 mounting interface, 160 mm bore, 80 mm stroke, force, and G3/4 port.
It features a G3/4 port and provides 10053 N push / 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa.
