This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X200N, 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 SI160X200N
The AirTAC SI160 Standard Cylinder SI160X200N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X200N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X200N
The AirTAC SI160X200N is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 200 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI160X200N. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke, force, and port size for existing fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SI160X200N lacks a magnet (-S) so it cannot take a sensor, and its NBR seals suit -20 to +70 C (Viton H raises this to 150 C). For load holding, note the cushion only decelerates; use SAIL or BSAI lock variants.

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 SAI160X200N 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 SI160X200N Is Used
Heavy Press Clamping
Generates 10053 N at 0.5 MPa to secure large metal castings during machining operations.
Industrial Material Handling
Shifts heavy fabricated structural components along production lines with reliable 30-500 mm/s speed.
Replacing the Airtac SI160 Standard Cylinder SI160X200N with the SAI160X200N
To replace the discontinued SI160X200N, order the SAI160X200N, confirming the ISO 15552 mounting interface, 160 mm bore, 200 mm stroke, G3/4 port (PT/G/NPT), and NBR seals. This SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. For sizing, the 160 mm bore yields 10053 N push at 0.5 MPa; a 125 mm bore offers 6136 N, while a 200 mm bore provides 15708 N. The cushion only decelerates; for holding loads, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 200 mm stroke, side-load risks are low, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X200N
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
