This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX75, 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 SI160AX75
The AirTAC Airtac SI160 Standard Cylinder SI160AX75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX75
The AirTAC SI160AX75 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 75 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160AX75, which matches the exact ISO 15552 mounting interface, stroke, force, and accessories.
This SKU lacks a magnet (-S) and cannot accept legacy CS1-B/DS1-B sensors. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. For load holding, note that standard cushions only decelerate; use the SAIL or BSAI lock variants. The -A suffix denotes a SUS420J2 stainless rod.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SI160 Standard Cylinder SI160AX75 Is Used
Heavy Press Clamping
Generates 14074 N at 0.7 MPa to secure large steel fabrications during heavy-duty machining and welding operations.
Injection Molding Extraction
Uses the 9425 N pull force at 0.5 MPa to reliably extract dense molded components from industrial tooling.
Pallet Lift Stations
Drives robust 75 mm stroke lifting mechanisms for heavy pallets, safely handling loads near the 512 kg vertical limit.
Replacing the Airtac SI160 Standard Cylinder SI160AX75 with the SAI160AX75
To replace the SI160AX75, order the SAI160AX75. Verify the ISO 15552 mounting interface, 75 mm stroke, G3/4 port (PT/G/NPT thread options), and your specific mounting accessory. This SKU has no magnet, so it cannot support position sensing; if sensing is needed, order an SAI with the -S suffix for CS1-B/DS1-B compatibility. Sizing both ways: the 160 mm bore yields 10053 N push at 0.5 MPa (2050 kgf max at 1.0 MPa); a 125 mm bore offers 6136 N, while a 200 mm bore provides 15708 N. Because this is a plain double-acting cylinder, it will not hold a load without live air—the cushions only decelerate. For dead-load security, use an external pilot check valve or the SAIL/BSAI lock variants. The SUS420J2 rod (-A) suits corrosive environments.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX75
- ✓ 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 SI160AX75 FAQ
Yes, the SI160AX75 is discontinued. The direct replacement is the SAI160AX75. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 75 mm stroke, 10053 N force, G3/4 port, and mounting interface.
This double-acting cylinder uses a G3/4 port. Force outputs are: 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; with a theoretical maximum of 2050 kgf at 1.0 MPa.
