This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1310, 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 SI160X1310
The AirTAC SI160 Standard Cylinder SI160X1310 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1310mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1310, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1310
The AirTAC SI160X1310 is a discontinued double-acting ISO 15552 profile cylinder, delivering a robust 10053 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI160X1310. This direct upgrade matches the original 160 mm bore, 1310 mm stroke, G3/4 port, and ISO 15552 mounting interface, fitting existing fixtures perfectly. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this SKU lacks a magnet (-S) and cannot accept position sensors.
The current SAI family expands functionality with variants the SI lacked, including the SAIL air-released lock, SAIF integrated valve, and BSAI clamp-lock. The standard cylinder does not hold load without live air; the 50 mm adjustable cushions only decelerate near stroke ends. For load holding on air loss, specify an external rod lock or pilot check valve. With a 1310 mm stroke, prevent rod bending by guiding the load externally to avoid side-loading.

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 SI160X1310 Is Used
Heavy Machinery Ejection
Provides the 10053 N push force needed to eject heavy formed parts from large presses, utilizing the full 1310 mm stroke to clear the machine bed safely.
Bulk Material Diversion
Actuates heavy-duty diverter arms on high-capacity bulk conveyors, using adjustable 50 mm cushions to decelerate the massive 160 mm bore piston smoothly.
Replacing the Airtac SI160 Standard Cylinder SI160X1310 with the SAI160X1310
To replace the discontinued SI160X1310, order the SAI160X1310, confirming the ISO 15552 mounting interface, 160 mm bore, 1310 mm stroke, G3/4 port, and M36x2 rod thread. Because this specific SKU has no magnet, it cannot support legacy CS1-B/DS1-B sensors; if position detection is needed, select an SAI160X1310S and use current AirTAC switches. When sizing, verify force in both directions: this class yields 10053 N push and 9425 N pull at 0.5 MPa, or 14074 N push at 0.7 MPa. If undersizing, a 125 mm bore provides 6136 N push at 0.5 MPa. A plain cylinder drifts without live air, so for load holding choose the SAIL lock, BSAI clamp-lock, or an external pilot check valve. The 1310 mm stroke demands an external guide to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1310
- ✓ 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 SI160X1310 FAQ
Yes, the SI160X1310 is discontinued. The direct replacement is the SAI160X1310. It features the same ISO 15552 mounting interface, 160 mm bore, 1310 mm stroke, output force, and G3/4 port, dropping directly into existing fixtures.
The 160 mm bore uses a G3/4 port. It generates 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. Speed is 30-500 mm/s.
