This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X480, 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 SI160X480
The AirTAC SI160 Standard Cylinder SI160X480 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 480mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X480, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X480
The AirTAC SI160X480 is a discontinued double-acting ISO 15552 profile cylinder delivering 10053 N push force at 0.5 MPa through a 160 mm bore and 480 mm stroke. The direct replacement is the SAI160X480, matching the exact G3/4 port, M36x2 thread, and mounting interface. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For sensing, note this specific SKU lacks the -S magnet and cannot accept a CS1-B/DS1-B switch.
The SAI family also introduces lock variants like the SAIL and BSAI that the legacy SI lacked. Operating pressure spans 0.15-1.0 MPa, with a Viton H seal option available to handle temperatures up to 150 C.

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 SI160X480 Is Used
Heavy Stamp Pressing
Drives large stamping dies requiring sustained 14074 N push force at 0.7 MPa to form thick metal plates.
Injection Molding
Actuates heavy mold halves over the 480 mm stroke, relying on external guides to prevent rod side-load bending.
Replacing the Airtac SI160 Standard Cylinder SI160X480 with the SAI160X480
To replace the discontinued SI160X480, order the SAI160X480 keeping the identical 160 mm bore, 480 mm stroke, G3/4 port, and ISO 15552 mounting fixtures. Because this SKU has no -S suffix, it cannot support magnetic sensing; if position detection is needed, select an SAI model with the magnet option and current AirTAC switches. If sizing down, the 125 mm bore yields 6136 N push at 0.5 MPa; if sizing up, the 200 mm bore provides 15708 N. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding consider the SAIL or BSAI lock variants, or an external pilot check valve. Finally, at 480 mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X480
- ✓ 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 SI160X480 FAQ
Yes, the SI160X480 is discontinued. The direct replacement is the SAI160X480. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 160 mm bore, 480 mm stroke, output force, G3/4 port, and mounting accessories.
This double-acting cylinder uses a G3/4 air port. It 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 maximum force of 2050 kgf at 1.0 MPa.
