This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1500S, 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 SI160X1500S
The AirTAC SI160 Standard Cylinder SI160X1500S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1500mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1500S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1500S
The AirTAC SI160X1500S is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 1500mm stroke, delivering 10053 N push force at 0.5 MPa via a G3/4 port. It is replaced by the SAI160X1500S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, force, and port size.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B sensors, while Viton H seals expand the operating temperature to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X1500S Is Used
Heavy Machinery Forming
Drives large press platens and forming dies where the 18095 N push force at 0.9 MPa is required to shape heavy steel components.
Bulk Material Transfer
Actuates large-scale diverter gates on heavy-duty bulk conveyors, utilizing the full 1500mm stroke to route high-volume aggregates.
Replacing the Airtac SI160 Standard Cylinder SI160X1500S with the SAI160X1500S
To replace the SI160X1500S, order the SAI160X1500S direct equivalent, verifying the ISO 15552 mounting interface, M36x2 rod thread, G3/4 port, and your specific mounting accessory (LB, FA, CA, TC). Because the 1500mm stroke is very long, use external guides to prevent rod bending and side-load damage. For sizing, the neighbouring 200mm bore offers higher force, while the 125mm bore provides 6136 N push at 0.5 MPa. 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 → SAI160X1500S
- ✓ 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 SI160X1500S FAQ
Yes, the SI160X1500S is discontinued. The direct replacement is the SAI160X1500S. It shares the identical ISO 15552 mounting interface, 160mm bore, 1500mm stroke, output force, and G3/4 port, so it fits existing fixtures perfectly.
This double-acting cylinder features a G3/4 air port. It delivers a push force of 10053 N and a pull force of 9425 N at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa.
