This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX1000S, 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 SI160AX1000S
The AirTAC SI160 Standard Cylinder SI160AX1000S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1000mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX1000S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX1000S
The AirTAC SI160AX1000S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore, 1000 mm stroke, and a SUS420J2 stainless steel rod. Delivering 10053 N push force at 0.5 MPa, it is superseded by the SAI160AX1000S direct replacement. This upgrade retains the exact G3/4 port, M36x2 thread, and ISO 15552 mounting interface, dropping directly into existing fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Because the -S magnet is present, it supports legacy CS1-B/DS1-B sensors, while the SAI family uses current AirTAC switches.

Where the Airtac SI160 Standard Cylinder SI160AX1000S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping presses requiring 10053 N push force at 0.5 MPa with a 1000 mm stroke.
Pallet Shuttle System
Actuates 512 kg vertical lifts in automated storage shuttles, utilizing the SUS420J2 rod for corrosion resistance.
Large Assembly Fixture
Positions heavy structural components in assembly fixtures, relying on the ISO 15552 mounting interface.
Replacing the Airtac SI160 Standard Cylinder SI160AX1000S with the SAI160AX1000S
To replace the SI160AX1000S, order the SAI160AX1000S, confirming the ISO 15552 interface, 1000 mm stroke, G3/4 port, and SUS420J2 stainless rod. If downsizing, a 125 mm bore yields 6136 N at 0.5 MPa; if upsizing, a 200 mm bore provides 15708 N. For this 1000 mm stroke, use external guides to prevent rod-bending and side-load damage. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAI family also adds the SAIF valve variant (bores 32-100).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX1000S
- ✓ 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 SI160AX1000S FAQ
Yes, the SI160AX1000S is discontinued. The direct replacement is the SAI160AX1000S. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 1000 mm stroke, force, G3/4 port, and mounting interface.
The bore is 160 mm with a G3/4 port. Force ratings 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.
