This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X90, 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 SI160X90
The AirTAC Airtac SI160 Standard Cylinder SI160X90 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 90mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X90, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X90
The AirTAC SI160X90 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 90 mm stroke, delivering a thrust of 10053 N at 0.5 MPa. It features a 40 mm carbon steel piston rod, M36x2 rod thread, and a G3/4 air port. Because this legacy unit lacks a magnet (-S), it cannot accept position sensors.
You must order the direct replacement SAI160X90 to maintain existing fixtures. It shares the exact ISO 15552 mounting interface, bore, stroke, force, and port size, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI160X90 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 SAI160X90 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 SI160X90 Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring substantial push force and robust 40 mm rod stability.
Pallet Actuation
Shifts loaded pallets or heavy material carts in automated distribution hubs with steady kinetic output.
Large Mold Clamping
Secures oversized injection molds or heavy industrial fixtures safely during high-tonnage manufacturing cycles.
Replacing the Airtac SI160 Standard Cylinder SI160X90 with the SAI160X90
To replace the discontinued SI160X90, order the SAI160X90. Confirm the ISO 15552 mounting interface, 160 mm bore, 90 mm stroke, G3/4 port (PT/G/NPT thread options), and your specific mounting accessory. This non-magnetic SKU cannot support CS1-B/DS1-B sensors; if sensing is needed, specify a magnet (-S) on the new SAI. Sizing both ways: a 200 mm bore offers higher force, while a 125 mm bore provides 6136 N push at 0.5 MPa. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAI family also includes the SAIF self-valve (bores 32-100) and high-temp Viton H seals (0-150 C).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X90
- ✓ 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 SI160X90 FAQ
Yes, the SI160X90 is discontinued. The direct replacement is the SAI160X90. It shares the identical ISO 15552 mounting interface, 160 mm bore, 90 mm stroke, output force, and G3/4 port, fitting seamlessly into existing fixtures.
This double-acting cylinder features a G3/4 air port. It delivers a push force of 10053 N and pull force of 9425 N at 0.5 MPa, 14074 N at 0.7 MPa, 18095 N at 0.9 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa.
