This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1100S, 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 SI160X1100S
The AirTAC SI160 Standard Cylinder SI160X1100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1100S
The AirTAC SI160X1100S is a discontinued double-acting ISO 15552 profile cylinder, delivering a push force of 10053 N at 0.5 MPa. It features a 160mm bore, 1100mm stroke, and a G3/4 air port. The direct replacement is the SAI160X1100S, retaining the exact ISO 15552 mounting interface, output force, and port size to fit existing fixtures seamlessly.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The original SI-SKU includes a piston magnet for CS1-B/DS1-B sensors, while the SAI family adds SAIL and BSAI lock variants absent in the legacy line.

Where the Airtac SI160 Standard Cylinder SI160X1100S Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring up to 18095 N of thrust at 0.7 MPa, utilizing the 160mm bore for heavy industrial metalworking.
Automated Line Transfer
Shifts substantial bulk materials or large assemblies between workstations, where the G3/4 port ensures high airflow for maintaining 30-500 mm/s operating speeds.
Replacing the Airtac SI160 Standard Cylinder SI160X1100S with the SAI160X1100S
To replace the discontinued SI160X1100S, order the SAI160X1100S. Confirm the ISO 15552 mounting interface, 160mm bore, 1100mm stroke, G3/4 port, and your specific mounting accessory. The -S suffix indicates a piston magnet for position sensing; the original used CS1-B/DS1-B switches, while the SAI takes current AirTAC sensors. If sizing down, the 125mm bore offers 6136 N push at 0.5 MPa; if sizing up, the 200mm bore provides 15708 N. Note that a plain cylinder drifts on air loss as the cushion only decelerates—for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. With a 1100mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1100S
- ✓ 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 SI160X1100S FAQ
Yes, the SI160X1100S is discontinued. The direct replacement is the SAI160X1100S. It is dimensionally interchangeable per ISO 15552, keeping the same 160mm bore, 1100mm stroke, output force, G3/4 port, and mounting interface.
The 160mm bore provides a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. At 0.7 MPa it pushes 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa, with an operating speed of 30-500 mm/s.
