This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X575S, 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 SI160X575S
The AirTAC SI160 Standard Cylinder SI160X575S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 575mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X575S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X575S
The AirTAC SI160X575S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 575 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI160X575S, a direct upgrade retaining the exact ISO 15552 mounting interface, M36x2 thread, and 50 mm cushions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line. Your -S suffix means a piston magnet for CS1-B/DS1-B switches.

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 SI160X575S Is Used
Heavy Stamp Press Feed
Drives robust 575 mm displacement to load thick plate material into mechanical presses, utilizing the 10053 N push force at 0.5 MPa.
Large Mold Extraction
Pushes heavy industrial molds out of casting machinery over the 575 mm travel, relying on adjustable 50 mm cushions to decelerate the high moving mass.
Replacing the Airtac SI160 Standard Cylinder SI160X575S with the SAI160X575S
To replace your SI160X575S, order the SAI160X575S. Confirm the ISO 15552 mounting accessory (LB, FA, CA, TC) and port thread (PT, G, NPT) match your fixture. The 575 mm stroke is within the 1500 mm standard limit, but at this length you must use external guides to prevent rod-bending and side-load damage. Sizing both ways: a 200 mm bore offers more force, while a 125 mm bore provides 6136 N push at 0.5 MPa. This plain cylinder does not hold load without live air; the 50 mm cushion only decelerates. For load-holding on air loss, use the SAIL or BSAI lock variant, or an external pilot check valve. The -S magnet works with legacy CS1-B/DS1-B sensors; SAI uses current AirTAC switches.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X575S
- ✓ 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 SI160X575S FAQ
Yes, the SI160X575S is discontinued. The direct replacement is the SAI160X575S. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 575 mm stroke, output force, G3/4 port, and mounting interface.
At 0.5 MPa it provides 10053 N push and 9425 N pull force. At 0.7 MPa push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical maximum force is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
