This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX200S, 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 SI160AX200S
The AirTAC SI160 Standard Cylinder SI160AX200S 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 SAI160AX200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX200S
The AirTAC SI160AX200S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 200 mm stroke. Built with an extruded aluminum barrel and a SUS420J2 stainless piston rod, it delivers a push force of 10053 N at 0.5 MPa. AirTAC replaced this legacy unit with the SAI160AX200S. This direct upgrade matches the exact ISO 15552 mounting interface, G3/4 port, M36x2 thread, and 2050 kgf max force, fitting existing fixtures perfectly.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The original SI-S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family uses current AirTAC switches. Note that plain cylinders drift without live air; for load holding, explore the 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 SAI160AX200S 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 SI160AX200S Is Used
Heavy Press Clamping
Generates 14074 N of push force at 0.7 MPa to secure large metal castings or heavy machinery frames during machining and pressing operations.
Stamping Press Feed
Drives robust 200 mm stroke indexing mechanisms in automated stamping lines, utilizing the 50 mm adjustable air cushions to halt heavy masses smoothly.
Replacing the Airtac SI160 Standard Cylinder SI160AX200S with the SAI160AX200S
To replace the discontinued SI160AX200S, order the SAI160AX200S. Verify your ISO 15552 mounting accessories (LB, FA, TC, etc.), the G3/4 air port, and the M36x2 rod thread. The -S magnet and -A SUS420J2 stainless rod carry over directly. Operating speed is 30-500 mm/s. Sizing both ways: a neighbouring 200 mm bore offers higher thrust, while a 125 mm bore is more compact. At 0.5 MPa, this 160 mm bore pushes 10053 N and pulls 9425 N. If your application requires load holding on air loss, note that the standard cushion only decelerates; you must add an external rod lock, a pilot check valve, or specify the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX200S
- ✓ 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 SI160AX200S FAQ
Yes, the AirTAC SI160AX200S is discontinued. The direct replacement is the SAI160AX200S. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 200 mm stroke, G3/4 port, and mounting interface. You simply order the SAI equivalent.
This double-acting cylinder features a G3/4 air port and an M36x2 rod thread. The thrust output is 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa.
