This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X150, 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 SI160X150
The AirTAC SI160 Standard Cylinder SI160X150 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 SAI160X150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X150
The AirTAC SI160X150 is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 150 mm stroke. It delivers 10053 N push and 9425 N pull force at 0.5 MPa, operating with a G3/4 port, M36x2 rod thread, and 50 mm adjustable air cushions. AirTAC replaced this legacy unit with the SAI160X150, a direct replacement sharing identical ISO 15552 mounting dimensions, output force, and port size.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. Because this specific SKU lacks the -S magnet, it cannot accept position sensors; the SAI family also adds SAIL and BSAI lock variants absent from 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 SAI160X150 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 SI160X150 Is Used
Heavy Press Forming
Drives large stamping and forming presses requiring up to 10053 N of push force at 0.5 MPa, utilizing the 50 mm cushions to absorb heavy kinetic energy.
Automated Clamp Systems
Secures large fabricated components during machining or welding, providing stable 9425 N pull force for robust fixture holding.
Replacing the Airtac SI160 Standard Cylinder SI160X150 with the SAI160X150
To replace the SI160X150, order the SAI160X150 ensuring the ISO 15552 mounting interface, 150 mm stroke, G3/4 port (PT/G/NPT), and accessory type match your fixture. This non-magnetic SKU cannot take a sensor, so if position feedback is needed, select an SAI160X150S and use current AirTAC switches. Sizing checks: the 125 mm bore offers 6136 N push, while the 200 mm bore yields 15708 N at 0.5 MPa. Note that a plain cylinder drifts on air loss as cushions only decelerate; for load holding, specify the SAIL or BSAI lock variant, or use an external rod lock. Operating speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X150
- ✓ 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 SI160X150 FAQ
Yes, the SI160X150 is discontinued. The direct replacement is the AirTAC SAI160X150. It features the same ISO 15552 mounting interface, 160 mm bore, 150 mm stroke, output force, and G3/4 port, fitting directly into existing fixtures.
The G3/4 port pairs with a 40 mm rod. At 0.5 MPa it provides 10053 N push and 9425 N pull. At 0.7 MPa push is 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
