This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX200STC, 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 SI160BX200STC
The AirTAC SI160 Standard Cylinder SI160BX200STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX200STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX200STC
The AirTAC SI160BX200STC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 200 mm stroke. It delivers 10053 N push force at 0.5 MPa and features a SUS304 stainless piston rod (-B), a piston magnet (-S), and a TC trunnion mount. AirTAC replaced this legacy unit with the SAI160BX200STC—a direct sharing the same ISO 15552 mounting interface, bore, output force, G3/4 port, and stroke.
The SAI upgrade retains all ratings but introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note that a standard cylinder drifts without live air; the cushion only decelerates. For load holding, consider the SAIL or BSAI lock variants.

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 SAI160BX200STC 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 SI160BX200STC Is Used
Heavy Press Clamping
Generates 14074 N of thrust at 0.7 MPa to secure large steel fabrications during machining or welding operations.
Injection Mould Ejection
Delivers robust ejection force with a corrosion-resistant SUS304 rod, ideal for humid or washdown manufacturing environments.
Replacing the Airtac SI160 Standard Cylinder SI160BX200STC with the SAI160BX200STC
To replace the SI160BX200STC, order the SAI160BX200STC. Confirm the ISO 15552 TC trunnion mounting interface, the 200 mm stroke, the G3/4 port, and the -B SUS304 rod. The -S magnet works with legacy CS1-B/DS1-B sensors, though the SAI family uses current AirTAC switches. Sizing both ways: this 160 mm bore yields 10053 N push at 0.5 MPa; if you need less force, a 125 mm bore offers 6136 N. If your application requires holding the load on air loss, do not rely on the air cushion—it only decelerates near stroke end. Instead, specify an external pilot check valve, a rod lock, or the SAIL/BSAI lock variant. For any stroke over 300 mm, guide the load to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX200STC
- ✓ 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 SI160BX200STC FAQ
Yes, the AirTAC SI160BX200STC is discontinued. The direct replacement is the SAI160BX200STC. It is dimensionally interchangeable per the ISO 15552 mounting interface, maintaining the exact same 160 mm bore, 200 mm stroke, output force, G3/4 port, and TC trunnion mounting.
The G3/4 port feeds a 40 mm piston rod. 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; with a theoretical maximum of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
