This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X950, 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 SI160X950
The AirTAC Airtac SI160 Standard Cylinder SI160X950 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 950mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X950, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X950
The AirTAC SI160X950 is a discontinued double-acting ISO 15552 profile cylinder delivering 10053 N of push force at 0.5 MPa through a 950 mm stroke. The direct replacement is the SAI160X950, retaining the exact 160 mm bore, G3/4 port, M36x2 rod thread and mounting interface. This updated SAI version features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life.
Because this specific SKU lacks the -S magnet suffix, it cannot accept position sensors like the legacy CS1-B or DS1-B switches. The SAI family also introduces SAIL and BSAI lock variants absent from the legacy SI line.

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 SI160X950 Is Used
Heavy Stamping Presses
Drives large heavy-metal forming tools where the 10053 N push force at 0.5 MPa handles substantial die resistance over the 950 mm travel.
Bulk Material Diversion
Actuates heavy-duty routing gates on aggregate or mining conveyor lines, relying on the 50 mm adjustable air cushions to decelerate the massive payload.
Replacing the Airtac SI160 Standard Cylinder SI160X950 with the SAI160X950
To replace the SI160X950, order the SAI160X950 and verify your ISO 15552 mounting interface, bore, and 950 mm stroke. Confirm the G3/4 air port and your thread standard (PT, G, or NPT). Since this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI variant if position detection is required. When sizing, a neighboring 200 mm bore offers higher force, while a 125 mm bore provides less. At 950 mm, the rod is susceptible to bending under side loads—always use external guides to prevent premature seal wear. A plain cylinder drifts on air loss; for load holding, use the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X950
- ✓ 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 SI160X950 FAQ
Yes, the AirTAC SI160X950 is discontinued. The direct replacement is the SAI160X950. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 950 mm stroke, output force, G3/4 port, and mounting accessories. You simply order the SAI160X950 to upgrade.
The SI160X950 operates at 30-500 mm/s. 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 maximum of 2050 kgf at 1.0 MPa. It uses a G3/4 port and a M36x2 rod thread.
