This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X215, 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 SI160X215
The AirTAC SI160 Standard Cylinder SI160X215 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 215mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X215, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X215
The AirTAC SI160X215 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 215 mm stroke, delivering 10053 N push force at 0.5 MPa through its G3/4 port. AirTAC replaced this legacy unit with the SAI160X215 direct replacement. It shares the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions, dropping directly into existing fixtures.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For load holding, note that a standard cylinder drifts without live air; the cushions only decelerate. Use the SAIL or BSAI lock variants, or an external pilot check valve. This non-magnet SKU cannot accept a sensor.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SI160 Standard Cylinder SI160X215 Is Used
Heavy Stamping Press
Drives large stamping dies requiring 10053 N push at 0.5 MPa, utilizing the 50 mm adjustable cushions to halt the 215 mm stroke smoothly.
Replacing the Airtac SI160 Standard Cylinder SI160X215 with the SAI160X215
To replace the discontinued SI160X215, order the SAI160X215. Confirm the ISO 15552 mounting interface, 160 mm bore, 215 mm stroke, G3/4 port, and M36x2 thread. Because this SKU lacks the -S magnet, it cannot support CS1-B/DS1-B sensors; order a magnet-equipped SAI if position detection is required. Sizing both ways: the 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N. The 160 mm bore provides 14074 N at 0.7 MPa. For suspended loads, a plain cylinder drifts on air loss—cushions only decelerate—so specify the SAIL air-released lock, BSAI clamp-lock, or an external rod lock. The SAI family also offers high-temp Viton H seals (0-150 C) and SAIF integrated valves (bores 32-100).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X215
- ✓ 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 SI160X215 FAQ
Yes, the AirTAC SI160X215 is discontinued. The direct replacement is the SAI160X215. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 215 mm stroke, 10053 N force, G3/4 port, and mounting interface.
This double-acting cylinder features a G3/4 port, M36x2 rod thread, and 50 mm cushions. Force 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 maximum theoretical force of 2050 kgf at 1.0 MPa.
