This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X65, 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 SI160X65
The AirTAC Airtac SI160 Standard Cylinder SI160X65 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 65mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X65, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X65
The AirTAC SI160X65 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 65 mm stroke, delivering 10053 N push force at 0.5 MPa. The direct replacement is the SAI160X65, featuring the exact same interface, G3/4 port, and output force. This SKU lacks the -S magnet and therefore cannot accept a position sensor.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SAI family also adds lock variants like the SAIL and BSAI that the legacy SI lacked.

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 SI160X65 Is Used
Heavy Press Clamping
Generates 10053 N of push force at 0.5 MPa to secure large steel plates during machining or welding operations.
Industrial Door Control
Drives massive automated facility doors, utilizing the 50 mm adjustable air cushions to decelerate the heavy structure smoothly.
Replacing the Airtac SI160 Standard Cylinder SI160X65 with the SAI160X65
To replace the discontinued SI160X65, order the SAI160X65. Confirm the ISO 15552 mounting interface, the 65 mm stroke, and the G3/4 port. Because this specific SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped version if position feedback is needed. At 0.5 MPa this bore yields 10053 N push and 9425 N pull force; if sizing down, the 125 mm bore offers 6136 N push. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, specify the SAIL or BSAI lock variant, or use an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X65
- ✓ 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 SI160X65 FAQ
Yes, the AirTAC SI160X65 is discontinued. The direct replacement is the SAI160X65, which shares the identical ISO 15552 mounting interface, 160 mm bore, 65 mm stroke, output force, and G3/4 port.
It features a G3/4 air port, a 40 mm rod, and an M36x2 rod thread. 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, with a theoretical maximum of 2050 kgf at 1.0 MPa.
