This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX190S, 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 SI160BX190S
The AirTAC SI160 Standard Cylinder SI160BX190S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 190mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX190S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX190S
The AirTAC SI160BX190S is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 190mm stroke. It delivers 10053 N push force at 0.5 MPa and features a SUS304 stainless piston rod, G3/4 port, and a built-in magnet for CS1-B/DS1-B sensors. The direct replacement is the SAI160BX190S, which shares the exact same ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI upgrade introduces a refined piston seal utilizing two Y-shaped one-way elements for extended lifespan and lower start-up pressure. For applications needing load holding on air loss, the SAI family adds SAIL and BSAI lock variants the SI lacked.

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 SI160BX190S Is Used
Heavy Press Clamping
Applies the 14074 N push force at 0.7 MPa to secure large metal castings or heavy assemblies during machining and pressing operations.
Large Mold Ejection
Ejects substantial injection molds or heavy industrial components over a 190mm stroke, relying on adjustable 50mm air cushions to decelerate.
Replacing the Airtac SI160 Standard Cylinder SI160BX190S with the SAI160BX190S
To replace the discontinued SI160BX190S, order the SAI160BX190S. Verify your ISO 15552 mounting accessory (LB, FA, CA, TC, etc.), the G3/4 air port, and the M36x2 rod thread. The -S magnet enables legacy CS1-B/DS1-B sensors, though the SAI replacement uses current AirTAC switches. If you need to size up or down, adjacent bores are 125mm and 200mm; at 0.5 MPa this 160mm bore yields 10053 N push and 9425 N pull. A plain cylinder drifts without live air, so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. For this 190mm stroke, guide external loads to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX190S
- ✓ 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 SI160BX190S FAQ
Yes, the SI160BX190S is discontinued. The direct replacement is the SAI160BX190S. It is dimensionally interchangeable per ISO 15552, matching the 160mm bore, 190mm stroke, G3/4 port, and mounting interface, but adds an upgraded piston seal.
This double-acting cylinder has a G3/4 port. The force output is 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.
