This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1300STC, 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 SI160X1300STC
The AirTAC SI160 Standard Cylinder SI160X1300STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1300mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1300STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1300STC
The AirTAC SI160X1300STC is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 1300mm stroke. It delivers 10053N push force at 0.5MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160X1300STC, a direct upgrade retaining the exact ISO 15552 mounting interface, M36x2 rod thread, and TC trunnion hardware.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For position sensing, this -S model uses legacy CS1-B/DS1-B switches, whereas the SAI family uses current AirTAC sensors.

Where the Airtac SI160 Standard Cylinder SI160X1300STC Is Used
Heavy Stamp Press Feed
Drives robust 1300mm carriage strokes to feed thick sheet metal into large stamping presses, utilizing the 10053N push force at 0.5MPa.
Large Mold Actuation
Shifts heavy industrial molding tooling along the 1300mm travel path, relying on the rigid TC trunnion mount to absorb pivot stresses.
Replacing the Airtac SI160 Standard Cylinder SI160X1300STC with the SAI160X1300STC
To replace the SI160X1300STC, order the SAI160X1300STC. Confirm the ISO 15552 TC trunnion mounting interface, 160mm bore, 1300mm stroke, G3/4 port, and the -S magnet requirement. If you need to downsize, the 125mm bore yields 6136N push at 0.5MPa; if you need more force, the 200mm bore provides 15708N. Note that a plain double-acting cylinder drifts on air loss—the cushion only decelerates near stroke end. For load holding, specify an external rod lock, a pilot check valve, or the SAIL/BSAI lock variant. Because 1300mm exceeds typical lengths, use an external guide to prevent rod bending and side-load damage. Operating speed is 30-500mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1300STC
- ✓ 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 SI160X1300STC FAQ
Yes, the SI160X1300STC is discontinued. The direct replacement is the SAI160X1300STC. It shares the same ISO 15552 mounting interface, 160mm bore, 1300mm stroke, output force, G3/4 port, and TC mounting, fitting existing fixtures perfectly.
The 160mm bore features a G3/4 port and provides 10053N push / 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a theoretical max force of 2050kgf at 1.0MPa. It uses a 40mm rod with an M36x2 thread and 50mm adjustable cushions.
