This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1200, 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 SI160X1200
The AirTAC SI160 Standard Cylinder SI160X1200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1200
The AirTAC SI160X1200 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1200 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160X1200, matching the bore, stroke, force, port, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This non-magnet SKU cannot take a sensor. For higher heat, Viton H seals raise the limit to 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 SI160X1200 Is Used
Heavy Press Forming
Generates 14074 N of push force at 0.7 MPa, ideal for actuating large stamping presses and heavy-duty forming fixtures.
Large Door Actuation
Drives substantial industrial bulkhead doors or heavy safety gates across a 1.2 meter span using standard ISO 15552 trunnion mounts.
Replacing the Airtac SI160 Standard Cylinder SI160X1200 with the SAI160X1200
To replace the SI160X1200, order the SAI160X1200 and confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), G3/4 port, and M36x2 rod thread. Since this is a non-S SKU, it cannot accept a CS1-B or DS1-B sensor. If sizing down, a 125 mm bore yields 6136 N push at 0.5 MPa; if sizing up, a 200 mm bore yields 15708 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify the SAIL or BSAI lock variant. With a 1200 mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1200
- ✓ 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 SI160X1200 FAQ
Yes, the SI160X1200 is discontinued. The direct replacement is the SAI160X1200. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 1200 mm stroke, 10053 N force, G3/4 port, and mounting interface.
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 max force of 2050 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-500 mm/s, and it uses a G3/4 port.
