This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X150SH, 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 SI160X150SH
The AirTAC SI160 Standard Cylinder SI160X150SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X150SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X150SH
The AirTAC SI160X150SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 150 mm stroke. It delivers 10053 N push force at 0.5 MPa with a G3/4 air port. As an end-of-life unit, it is replaced by the SAI160X150SH, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting accessories.
The SAI replacement upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life. This -SH configuration includes a piston magnet for CS1-B/DS1-B switches and a Viton H seal extending temperature to 0-150 C. The SAI family also 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 | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X150SH 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 SI160X150SH Is Used
Heavy Pressing
Drives large stamping and forming presses requiring 10053 N push force at 0.5 MPa with stable ISO 15552 mounting.
High-Temp Ejection
Ejects cast or hot components from molds safely using the Viton H seal rated for 0 to 150 C environments.
Replacing the Airtac SI160 Standard Cylinder SI160X150SH with the SAI160X150SH
To replace the SI160X150SH, order the SAI160X150SH. It drops into existing fixtures per the ISO 15552 mounting interface. Confirm the G3/4 port, M36x2 rod thread, 50 mm cushions, magnet (-S) and Viton H high-temp seal (-H). Sizing both ways: the 160 mm bore yields 10053 N push at 0.5 MPa; dropping to a 125 mm bore gives 6136 N. A plain cylinder drifts on air loss as cushions only decelerate. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 150 mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X150SH
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
