This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X150CA, 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 SI160X150CA
The AirTAC Airtac SI160 Standard Cylinder SI160X150CA 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 SAI160X150CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X150CA
The AirTAC SI160X150CA is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 150 mm stroke. It delivers 10053 N push force at 0.5 MPa. The direct replacement is the SAI160X150CA, retaining the same CA clevis mount, G3/4 port, and M36x2 rod thread.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This non-magnet SKU cannot take a sensor, unlike the CS1-B/DS1-B used on -S models.

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 SAI160X150CA 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 SI160X150CA Is Used
Heavy Stamping
Drives large press dies requiring 10053 N push force at 0.5 MPa with stable CA clevis mounting.
Automotive Assembly
Actuates heavy welding fixtures and robotic clamping arms needing robust 160 mm bore power.
Replacing the Airtac SI160 Standard Cylinder SI160X150CA with the SAI160X150CA
To replace the SI160X150CA, order the SAI160X150CA, confirming the ISO 15552 CA clevis interface, 150 mm stroke, and G3/4 port. Sizing both ways: the 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N. For load holding on air loss, note this plain cylinder drifts; the cushion only decelerates. Use an external pilot check valve or the SAIL/BSAI lock variants. The SAI family also adds the SAIF valve option for smaller bores.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X150CA
- ✓ 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 SI160X150CA FAQ
Yes, the SI160X150CA is discontinued. The direct replacement is the SAI160X150CA. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 150 mm stroke, CA mounting, and G3/4 port.
The G3/4 ported 160 mm bore delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a max force of 2050 kgf at 1.0 MPa. The piston rod is 40 mm with an M36x2 thread.
