This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX60S, 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 SI160AX60S
The AirTAC Airtac SI160 Standard Cylinder SI160AX60S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 60mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX60S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX60S
The AirTAC SI160AX60S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 60 mm stroke. It delivers a robust 10053 N push force at 0.5 MPa. The direct replacement is the SAI160AX60S, which maintains the exact same ISO 15552 mounting interface, bore, stroke, G3/4 port, and output force for seamless fixture integration.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This specific unit includes the -S magnet for legacy CS1-B/DS1-B sensors and the -A SUS420J2 stainless steel rod.

Where the Airtac SI160 Standard Cylinder SI160AX60S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 10053 N of push force at 0.5 MPa with stable 60 mm travel.
Injection Mold Clamp
Secures large injection molding halves using the SUS420J2 stainless rod option for humid factory environments.
Replacing the Airtac SI160 Standard Cylinder SI160AX60S with the SAI160AX60S
To replace the SI160AX60S, order the SAI160AX60S. Confirm the ISO 15552 mounting interface, the 60 mm stroke, the G3/4 port, and your specific mounting accessory (LB, FA, TC, etc.). The -S magnet enables current AirTAC switches, while the -A rod specifies SUS420J2 stainless steel over standard carbon steel. If sizing down, the 125 mm bore offers 6136 N push at 0.5 MPa; if sizing up, the 200 mm bore provides 15708 N. Remember that a plain cylinder does not hold load without live air—the cushion only decelerates. For load holding on air loss, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The SAI family also adds the SAIF self-valve option for bores 32-100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX60S
- ✓ 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 SI160AX60S FAQ
Yes, the AirTAC SI160AX60S is discontinued. The direct replacement is the SAI160AX60S. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 60 mm stroke, 10053 N force, G3/4 port, and mounting accessories.
The G3/4 port feeds a 40 mm rod. Forces are: push 10053 N and pull 9425 N at 0.5 MPa; push 14074 N at 0.7 MPa; push 18095 N at 0.9 MPa; with a theoretical max of 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
