This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X100SH, 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 SI160X100SH
The AirTAC SI160 Standard Cylinder SI160X100SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X100SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X100SH
The AirTAC SI160X100SH is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 100mm stroke. It delivers 10053N push force at 0.5MPa, features a G3/4 port, and includes a piston magnet (-S) plus a high-temperature Viton H seal rated for 0 to 150C.
You must replace it with the direct replacement SAI160X100SH. It shares the exact ISO 15552 mounting interface, bore, stroke, force, and port. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure.

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 SAI160X100SH 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 SI160X100SH Is Used
Heavy Stamping
Drives large presses and stamping fixtures requiring 10053N push force at 0.5MPa with stable 160mm bore rigidity.
High-Temp Actuation
Operates in heated industrial zones up to 150C using the Viton H seal, ideal for plastics or drying lines.
Replacing the Airtac SI160 Standard Cylinder SI160X100SH with the SAI160X100SH
To replace this SI160X100SH, order the SAI160X100SH. Confirm the ISO 15552 mounting interface, the 100mm stroke, the G3/4 port, and your mounting accessory. The -S magnet enables legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches), while the -H Viton seal handles 0-150C environments. If you need less force, the 125mm bore offers 6136N push at 0.5MPa; for more power, the 200mm bore gives 15708N. Because this is a plain double-acting cylinder, it will not hold a load on air loss—the cushion only decelerates. For load holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. Even at 100mm stroke, verify side-load alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X100SH
- ✓ 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 SI160X100SH FAQ
Yes, the SI160X100SH is discontinued. The direct replacement is the SAI160X100SH. It shares the same ISO 15552 mounting interface, 160mm bore, 100mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The G3/4 port bore delivers 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a theoretical max of 2050kgf at 1.0MPa. It features a 40mm rod, M36x2 thread, and 50mm cushions.
