This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1020, 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 SI160X1020
The AirTAC SI160 Standard Cylinder SI160X1020 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1020mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1020, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1020
The AirTAC SI160X1020 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1020 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X1020, which shares the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions.
Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure. For load holding, note that standard cushions only decelerate; you need the SAIL lock or an external pilot check valve.

Where the Airtac SI160 Standard Cylinder SI160X1020 Is Used
Heavy Stamp Press Feed
Drives large metal blanks into a hydraulic press, utilizing the 10053 N push force to overcome heavy material resistance over the 1020 mm loading stroke.
Pallet Lift Ejection
Ejects loaded pallets from a machining cell, requiring the robust 160 mm bore and long 1020 mm travel to clear the work zone completely.
Large Mold Actuation
Shifts substantial injection mold halves, relying on the 9425 N pull force at 0.5 MPa to safely open the tooling without deflection.
Replacing the Airtac SI160 Standard Cylinder SI160X1020 with the SAI160X1020
To replace the SI160X1020, order the SAI160X1020. Confirm the ISO 15552 mounting fixture, G3/4 port, and M36x2 thread. Since this is a non-magnet SKU, sensing is impossible; if needed, switch to an -S SAI model for current AirTAC switches. At 0.5 MPa it yields 10053 N push / 9425 N pull; if undersized, the 200 mm bore offers more thrust. For the 1020 mm stroke, use external guides to prevent rod bending and side-load damage. The cushion only decelerates; for dead-load holding, use the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1020
- ✓ 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 SI160X1020 FAQ
Yes, the SI160X1020 is discontinued. The direct replacement is the SAI160X1020. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 160 mm bore, 1020 mm stroke, force, G3/4 port, and mounting accessories.
At 0.5 MPa it provides 10053 N push and 9425 N pull. At 0.7 MPa push is 14074 N, and 18095 N at 0.9 MPa. The theoretical max force is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, and it uses a G3/4 port.
