This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X750S, 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 SI160X750S
The AirTAC SI160 Standard Cylinder SI160X750S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 750mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X750S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X750S
The AirTAC SI160X750S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 750 mm stroke. Generating 10053 N push force at 0.5 MPa, its direct replacement is the SAI160X750S, sharing the exact G3/4 port, M36x2 thread, and ISO 15552 mounting interface.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line. This -S model carries a piston magnet for CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160X750S Is Used
Heavy Stamping Press
Drives large platens and heavy dies requiring 10053 N push force at 0.5 MPa, utilizing the adjustable 50 mm air cushions to absorb impact.
Large Assembly Fixture
Actuates heavy structural components over a 750 mm distance, requiring external guide rails to prevent rod bending on this long stroke.
Replacing the Airtac SI160 Standard Cylinder SI160X750S with the SAI160X750S
To replace the SI160X750S, order the SAI160X750S, verifying the ISO 15552 mounting interface, 750 mm stroke, G3/4 port, and magnet option. Operating speed is 30-500 mm/s. For sizing, a 125 mm bore yields 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N; alternatively, pushing 1.0 MPa on the 160 mm bore outputs a 2050 kgf max. Note that a 750 mm stroke requires external guides to prevent rod bending under side loads. 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 → SAI160X750S
- ✓ 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 SI160X750S FAQ
Yes, the AirTAC SI160X750S is discontinued. The direct replacement is the SAI160X750S. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 750 mm stroke, output force, G3/4 port, and mounting accessories.
The G3/4 port feeds a 40 mm rod. It delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N at 0.9 MPa, and a 2050 kgf maximum at 1.0 MPa. Speed is 30-500 mm/s.
