This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1980, 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 SI160X1980
The AirTAC SI160 Standard Cylinder SI160X1980 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1980mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1980, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1980
The AirTAC SI160X1980 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1980 mm stroke. Because 1980 mm exceeds the 1500 mm standard maximum, this is a non-standard, made-to-order length. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160X1980, sharing the same interface, force, and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet (-S), so it cannot take a CS1-B/DS1-B sensor. For high heat, Viton H seals raise the temperature range to 0-150 C.

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

Where the Airtac SI160 Standard Cylinder SI160X1980 Is Used
Automated Press Line
Drives heavy-duty press actuators where the 14074 N push force at 0.7 MPa is needed to form or stamp large metal components over a long 1980 mm travel distance.
Heavy Material Lift
Raises and lowers heavy pallets or machinery platens, utilizing the 10053 N push at 0.5 MPa to move loads safely within the 6032 N working load limit.
Long-Stroke Transfer
Shifts bulky fabricated parts between machining stations on an extended 1980 mm axis, requiring external guide rails to prevent rod bending during transit.
Replacing the Airtac SI160 Standard Cylinder SI160X1980 with the SAI160X1980
To replace the SI160X1980, order the SAI160X1980. Confirm the ISO 15552 mounting interface, 160 mm bore, 1980 mm non-standard stroke, G3/4 port, and M36x2 rod thread. This non-magnetic SKU cannot accept position sensors. Because the 1980 mm stroke exceeds standard limits and generates high side loads, use external guides to prevent rod bending. Sizing both ways: a 200 mm bore offers more force, while a 125 mm bore provides 6136 N push at 0.5 MPa. The air cushion only decelerates; it does not hold load. For load holding on air loss, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1980
- ✓ 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 SI160X1980 FAQ
Yes, the SI160X1980 is discontinued. The direct replacement is the SAI160X1980. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 1980 mm stroke, G3/4 port, and mounting fixtures.
This double-acting cylinder uses 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. Speed is 30-500 mm/s.
