This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX750, 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 SI160AX750
The AirTAC SI160 Standard Cylinder SI160AX750 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 750mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX750, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX750
The AirTAC SI160AX750 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 750 mm stroke. It delivers 10053 N push force at 0.5 MPa, featuring a 40 mm carbon steel rod, M36x2 thread, and G3/4 port. The direct replacement is the SAI160AX750, matching the exact bore, stroke, force, and ISO 15552 mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet (-S) and cannot take a sensor, though legacy SI sensors were CS1-B/DS1-B. For high heat, Viton H seals raise the temperature limit to 150 C.

Where the Airtac SI160 Standard Cylinder SI160AX750 Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 10053 N push force at 0.5 MPa over a 750 mm travel distance.
Large Mold Handling
Shifts heavy injection molds into press beds, utilizing the M36x2 rod thread and 50 mm cushions.
Replacing the Airtac SI160 Standard Cylinder SI160AX750 with the SAI160AX750
To replace the SI160AX750, order the SAI160AX750. Confirm the ISO 15552 mounting interface, G3/4 port, 750 mm stroke, and SUS420J2 stainless rod (-A). This non-magnetic SKU cannot accept switches. For sizing, the 125 mm bore offers 6136 N [email protected], while the 200 mm bore provides 15708 N. At 750 mm stroke, use external guides to prevent rod bending and side-load damage. The air cushion only decelerates; it does not hold load on air loss. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX750
- ✓ 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 SI160AX750 FAQ
Yes, the SI160AX750 is discontinued. The direct replacement is the SAI160AX750. It shares the same ISO 15552 mounting interface, 160 mm bore, 750 mm stroke, output force, G3/4 port, and accessories, fitting directly into existing fixtures.
The G3/4 port bore delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
