This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X190SFTC, 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 SI160X190SFTC
The AirTAC SI160 Standard Cylinder SI160X190SFTC 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 SAI160X190SFTC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X190SFTC
The AirTAC SI160X190SFTC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore, 190 mm stroke, and an FTC trunnion mount. Built for heavy-duty tasks, it delivers a push force of 10053 N and pull of 9425 N at 0.5 MPa through a G3/4 port. AirTAC replaced this end-of-life unit with the SAI160X190SFTC, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The -S magnet pairs with legacy CS1-B/DS1-B sensors, while the SAI family introduces lock variants like the SAIL and BSAI 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 | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X190SFTC 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 SI160X190SFTC Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 10053 N of push force at 0.5 MPa, utilizing the adjustable 50 mm cushion to decelerate massive moving masses.
Large Mold Clamping
Secures oversized industrial molds in place using the 9425 N pull force at 0.5 MPa, relying on the G3/4 port for high-volume air flow.
Replacing the Airtac SI160 Standard Cylinder SI160X190SFTC with the SAI160X190SFTC
To replace the SI160X190SFTC, order the SAI160X190SFTC. Verify the ISO 15552 FTC trunnion interface, 160 mm bore, 190 mm stroke, G3/4 port, and the -S magnet for current AirTAC switches. If you need to scale, the neighboring 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore provides 15708 N; alternatively, pushing 0.7 MPa on this 160 mm bore generates 14074 N. Remember that a plain cylinder drifts without live air—the cushion only decelerates—so use an external pilot check valve or the SAIL/BSAI lock variant to hold loads. At 190 mm, side-load risks are low, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X190SFTC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
