This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1560, 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 SI160X1560
The AirTAC SI160 Standard Cylinder SI160X1560 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1560mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1560, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1560
The AirTAC SI160X1560 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1560 mm stroke. It delivers 10053 N push force at 0.5 MPa. Because 1560 mm exceeds the 1500 mm standard stroke limit, this is a non-standard, made-to-order length. The direct replacement is the SAI160X1560, matching the ISO 15552 mounting interface, bore, stroke, force, G3/4 port and accessories.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet (-S), so it cannot take 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 | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X1560 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 SI160X1560 Is Used
Heavy Stamp Presses
Drives large platens and heavy stamping dies using 10053 N of thrust at 0.5 MPa, relying on the 50 mm adjustable cushion to absorb end-of-stroke impact.
Long Transfer Arms
Actuates extended 1560 mm transfer mechanisms, requiring external guide rails to prevent rod bending and manage side loads over the long stroke.
Replacing the Airtac SI160 Standard Cylinder SI160X1560 with the SAI160X1560
To replace the SI160X1560, order the SAI160X1560. Verify the ISO 15552 mounting accessory (LB, FA, CA, TC), the G3/4 port thread (PT/G/NPT) and the M36x2 rod thread. Since this is a non-S SKU, it cannot accept position sensors; order a -S variant if switches are needed. Sizing both ways: a 200 mm bore offers more force, while a 125 mm bore provides 6136 N push at 0.5 MPa. The 1560 mm stroke exceeds the 1500 mm standard maximum, requiring a made-to-order unit; at this length, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1560
- ✓ 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 SI160X1560 FAQ
Yes, the SI160X1560 is discontinued. The direct replacement is the SAI160X1560. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 1560 mm stroke, output force, G3/4 port, and mounting interface, so it fits existing fixtures directly.
The G3/4 port feeds a 40 mm rod. Force outputs are: 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 max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
