This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1420, 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 SI160X1420
The AirTAC SI160 Standard Cylinder SI160X1420 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1420mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1420, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1420
The AirTAC SI160X1420 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1420 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160X1420, a direct upgrade retaining the exact interface, stroke, and output force.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This non-magnet SKU cannot take a sensor, unlike legacy CS1-B/DS1-B switches.

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 SAI160X1420 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 SI160X1420 Is Used
Heavy Stamp Press Feed
Drives large material handling arms in metal stamping lines, utilizing the 10053 N push force to move heavy billets into the press bed over the 1420 mm extension.
Pallet Shuttle Transfer
Shifts loaded pallets across conveyor gaps in automated distribution centers, requiring the extended reach and high kinetic energy absorption at stroke end.
Large Mold Ejection
Ejects dense automotive or structural molds from hydraulic presses, where the 9425 N pull force at 0.5 MPa reliably retracts the heavy tooling.
Replacing the Airtac SI160 Standard Cylinder SI160X1420 with the SAI160X1420
To replace the SI160X1420, order the SAI160X1420. Confirm the ISO 15552 mounting interface, bore, 1420 mm stroke, G3/4 port (PT/G/NPT), and mounting accessory. Because this is a 1420 mm stroke, prevent rod bending by using an external guide to absorb side loads. Sizing both ways: a 200 mm bore offers more force, while a 125 mm bore provides 6136 N push @0.5 MPa. This non-magnet version cannot accept position sensors. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1420
- ✓ 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 SI160X1420 FAQ
Yes, the AirTAC SI160X1420 is discontinued. The direct replacement is the SAI160X1420. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 1420 mm stroke, force, G3/4 port, and mounting fixtures.
The 160 mm bore 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. The speed range is 30-500 mm/s.
