This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X100FA, 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 SI160X100FA
The AirTAC Airtac SI160 Standard Cylinder SI160X100FA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X100FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X100FA
The AirTAC SI160X100FA is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 100 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a G3/4 port and an FA flange mounting interface. The direct replacement is the SAI160X100FA, matching the bore, stroke, force, port and ISO 15552 mounting dimensions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a magnet, so it cannot accept a CS1-B/DS1-B sensor. For high heat, Viton H seals raise the temperature range to 0-150 C.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SI160 Standard Cylinder SI160X100FA Is Used
Heavy Press Operations
Drives large stamping and forming presses using 10053 N of thrust at 0.5 MPa, securely mounted via the FA flange.
Industrial Clamp Systems
Clamps large fabricated steel components in welding jigs where the 160 mm bore provides massive holding power.
Replacing the Airtac SI160 Standard Cylinder SI160X100FA with the SAI160X100FA
To replace the SI160X100FA, order the SAI160X100FA and verify the ISO 15552 FA flange interface, 100 mm stroke, G3/4 port and M36x2 rod thread. Because this specific SKU has no -S magnet, it cannot support position sensing. Sizing both ways: the 160 mm bore yields 10053 N push at 0.5 MPa, while the neighboring 125 mm bore offers 6136 N. For load holding, know that a plain cylinder drifts on air loss—the cushion only decelerates. Use an external pilot check valve or the SAIL/BSAI lock variants. At 100 mm stroke, side-load risks are minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X100FA
- ✓ 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 SI160X100FA FAQ
Yes, the SI160X100FA is discontinued. The direct replacement is the SAI160X100FA. It shares the identical ISO 15552 mounting interface, 160 mm bore, 100 mm stroke, output force, G3/4 port and FA flange, fitting existing fixtures perfectly.
This double-acting cylinder has a G3/4 port. It delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical maximum force of 2050 kgf at 1.0 MPa.
