This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X175S, 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 SI160X175S
The AirTAC SI160 Standard Cylinder SI160X175S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 175mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X175S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X175S
The AirTAC SI160X175S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 175 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is directly replaced by the SAI160X175S direct equivalent.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL and BSAI lock variants absent in the SI line.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI160X175S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI160X175S 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 SI160X175S Is Used
Heavy Stamping
Drives large presses and stamping dies requiring 10053 N thrust at 0.5 MPa with stable 175 mm travel.
Automotive Assembly
Actuates heavy chassis clamps and robotic weld fixtures using its ISO 15552 mounting interface.
Replacing the Airtac SI160 Standard Cylinder SI160X175S with the SAI160X175S
To replace this SI160X175S, order the SAI160X175S to retain the exact ISO 15552 mounting interface, 175 mm stroke, G3/4 port, and M36x2 rod thread. If downsizing, a 125 mm bore yields 6136 N push at 0.5 MPa; if upsizing, 200 mm provides 15708 N. For load holding on air loss, note that a plain cylinder drifts and the 50 mm cushion only decelerates—select the SAIL lock variant or an external pilot check valve. Magnet (-S) is present for CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X175S
- ✓ 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 SI160X175S FAQ
Yes, the SI160X175S is discontinued. The direct replacement is the SAI160X175S, which shares the identical ISO 15552 mounting interface, 160 mm bore, 175 mm stroke, output force, and G3/4 port.
It features a G3/4 port and delivers 10053 N push / 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
