This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX95S, 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 SI160BX95S
The AirTAC SI160 Standard Cylinder SI160BX95S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 95mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX95S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX95S
The AirTAC SI160BX95S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 95 mm stroke. It delivers 10053 N push force at 0.5 MPa through its G3/4 port. The direct replacement is the SAI160BX95S, which matches the original ISO 15552 mounting interface, stroke, force and accessories.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU includes a SUS304 stainless steel rod and a magnetic piston for 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 | — |

Where the Airtac SI160 Standard Cylinder SI160BX95S Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring substantial thrust, utilizing the 10053 N push force at 0.5 MPa.
Stainless Rod Tooling
Operates in humid or washdown environments using the SUS304 rod option to resist corrosion during actuation cycles.
Replacing the Airtac SI160 Standard Cylinder SI160BX95S with the SAI160BX95S
To replace the SI160BX95S, order the SAI160BX95S and verify your ISO 15552 mounting interface, G3/4 port, and M36x2 rod thread. The -S magnet and -B SUS304 stainless rod carry over directly. If you need more force, the neighboring 200 mm bore yields 15708 N push at 0.5 MPa; if less is required, the 125 mm bore provides 6136 N. 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, though only for bores up to 100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX95S
- ✓ 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 SI160BX95S FAQ
Yes, the SI160BX95S is discontinued. The direct replacement is the SAI160BX95S. It is dimensionally interchangeable per ISO 15552, maintaining the same 160 mm bore, 95 mm stroke, G3/4 port, and mounting interface.
This double-acting cylinder features a G3/4 port and an M36x2 rod thread. It delivers 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 maximum of 2050 kgf at 1.0 MPa.
