This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX700S, 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 SI160AX700S
The AirTAC Airtac SI160 Standard Cylinder SI160AX700S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX700S
The AirTAC SI160AX700S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore, 700 mm stroke, and a SUS420J2 stainless piston rod. It delivers 10053 N push force at 0.5 MPa. The direct replacement is the SAI160AX700S, sharing the same interface, G3/4 port, and M36x2 thread.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The original -S magnet works with CS1-B/DS1-B sensors, while a Viton H seal option raises heat resistance to 150 C.

Where the Airtac SI160 Standard Cylinder SI160AX700S Is Used
Heavy Stamp Press Feeder
Drives large metal blanks into a hydraulic press, utilizing the 10053 N push force at 0.5 MPa to overcome heavy material friction.
Mold Clamping Station
Secures large injection molds in place, relying on the 160 mm bore and SUS420J2 stainless rod to resist corrosion in humid environments.
Replacing the Airtac SI160 Standard Cylinder SI160AX700S with the SAI160AX700S
To replace the SI160AX700S, order the SAI160AX700S and confirm the ISO 15552 mounting interface, 700 mm stroke, G3/4 port, and -S magnet for current AirTAC switches. If downsizing, a 125 mm bore yields 6136 N at 0.5 MPa; if upsizing, a 200 mm bore provides 15708 N. Because the 700 mm stroke invites rod bending, use external guides to prevent side-load damage. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX700S
- ✓ 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 SI160AX700S FAQ
Yes, the SI160AX700S is discontinued. The direct replacement is the SAI160AX700S. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 700 mm stroke, output force, G3/4 port, and mounting accessories.
This double-acting cylinder uses a G3/4 air port. It generates 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa.
