This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX300SH, 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 SI160BX300SH
The AirTAC SI160 Standard Cylinder SI160BX300SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 300mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX300SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX300SH
The AirTAC SI160BX300SH is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 300 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a SUS304 stainless piston rod (-B) for corrosion resistance, a Viton H high-temperature seal (0-150 C), and a G3/4 port. The direct replacement is the SAI160BX300SH, sharing the same interface, force, and mounting.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The original -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL and BSAI lock variants absent in the SI line.

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 SI160BX300SH Is Used
Heavy Machinery Forming
Drives large presses and forming tools where the 10053 N push force at 0.5 MPa and robust 160 mm profile barrel handle substantial industrial loads.
High-Temperature Handling
Operates in hot environments up to 150 C using the Viton H seal option, ideal for transferring heated molds or metal components in foundries.
Replacing the Airtac SI160 Standard Cylinder SI160BX300SH with the SAI160BX300SH
To replace the SI160BX300SH, order the SAI160BX300SH to retain the identical ISO 15552 mounting dimensions, 300 mm stroke, G3/4 port, and M36x2 rod thread. Confirm your mounting accessory (LB, FA, TC, etc.) and the -S magnet for current AirTAC switches. If downsizing, a 125 mm bore yields 6136 N at 0.5 MPa; if upsizing, a 200 mm bore provides 15708 N. Because this is a 300 mm stroke, use external guides to prevent rod bending and side-load damage. Remember, a standard cylinder drifts without live air—the cushion only decelerates end-of-stroke. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX300SH
- ✓ 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 SI160BX300SH FAQ
Yes, the AirTAC SI160BX300SH is discontinued. The direct replacement is the SAI160BX300SH. It is dimensionally interchangeable per ISO 15552, maintaining the same 160 mm bore, 300 mm stroke, G3/4 port, and mounting interface.
This double-acting cylinder uses a G3/4 air port. Theoretical forces 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 maximum force of 2050 kgf at 1.0 MPa. Speed range is 30-500 mm/s.
