This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X460S, 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 SI160X460S
The AirTAC SI160 Standard Cylinder SI160X460S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 460mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X460S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X460S
The AirTAC SI160X460S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 460 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X460S, matching the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions.
Upgrading to the SAI retains all ratings but adds a two Y-shaped one-way piston seal for low start-up pressure. The SAI family also introduces SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S suffix means a piston magnet for legacy CS1-B/DS1-B sensors.

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 SI160X460S Is Used
Heavy Press Clamping
Secures large steel plates in hydraulic press beds, utilizing the 10053 N push force at 0.5 MPa to hold workpieces firmly during heavy machining operations.
Pallet Lift Gates
Actuates heavy loading dock gates. The 460 mm stroke provides the travel needed to clear tall pallets, while the G3/4 port ensures rapid actuation within the 30-500 mm/s range.
Automated Assembly Indexing
Moves substantial tooling carriages along production lines. The 160 mm bore handles the mass, but external guides are critical over the 460 mm stroke to prevent rod bending.
Replacing the Airtac SI160 Standard Cylinder SI160X460S with the SAI160X460S
To replace the SI160X460S, order the SAI160X460S. Verify the ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/4 port, and the -S magnet for current AirTAC switches. Sizing both ways: if stepping down to bore 125, output drops to 6136 N push at 0.5 MPa; if increasing to 200, it jumps to 15708 N. For this 460 mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates. For load holding, specify the SAIL or BSAI lock variant, or use an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X460S
- ✓ 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 SI160X460S FAQ
Yes, the SI160X460S is discontinued. The direct replacement is the AirTAC SAI160X460S. It shares the identical ISO 15552 mounting interface, 160 mm bore, 460 mm stroke, output force, G3/4 port, and accessories, fitting directly into existing fixtures.
The bore is 160 mm with a G3/4 air port. Force output is 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. Operating speed is 30-500 mm/s.
