This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X200SH, 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 SI160X200SH
The AirTAC SI160 Standard Cylinder SI160X200SH 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 SAI160X200SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X200SH
The AirTAC SI160X200SH is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 200 mm stroke. Built for high temperatures, it features a Viton H seal (0 to 150 C) and a built-in piston magnet for legacy CS1-B/DS1-B sensors. Delivering 10053 N push force at 0.5 MPa via its G3/4 port, it is directly replaced by the SAI160X200SH.
The SAI160X200SH is a direct upgrade retaining the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions. It introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure.

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 SI160X200SH Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 10053 N of push force at 0.5 MPa, utilizing the 50 mm adjustable cushions to halt the massive moving mass smoothly.
High-Tact Automation
Operates in elevated ambient environments up to 150 C using the Viton H seal kit, actuating heavy gates or diverters where standard NBR seals would rapidly degrade.
Replacing the Airtac SI160 Standard Cylinder SI160X200SH with the SAI160X200SH
To replace the SI160X200SH, order the SAI160X200SH. Verify your ISO 15552 mounting fixtures, the G3/4 air port, the M36x2 rod thread, and the high-temp Viton H seal requirement. The -S magnet equips it for current AirTAC switches (replacing legacy CS1-B/DS1-B). If you need less force, the 125 mm bore offers 6136 N push at 0.5 MPa; if you need more, the 200 mm bore provides 15708 N. Remember, a standard cylinder drifts without live air—the cushion only decelerates. For load holding, use an external pilot check valve or explore the SAIL or BSAI lock variants. Since the 200 mm stroke exceeds 300 mm, ensure adequate guide support to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X200SH
- ✓ 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 SI160X200SH FAQ
Yes, the SI160X200SH is discontinued. The direct replacement is the SAI160X200SH. It shares the same ISO 15552 mounting interface, 160 mm bore, 200 mm stroke, G3/4 port, and output force, fitting directly into your existing fixtures.
The 160 mm bore generates 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 max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, and the G3/4 port supplies the required air volume.
