This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X2000, 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 SI160X2000
The AirTAC Airtac SI160 Standard Cylinder SI160X2000 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 2000mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X2000, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X2000
The AirTAC SI160X2000 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 2000 mm stroke. Delivering 10053 N push force at 0.5 MPa, it is replaced by the SAI160X2000. This direct successor shares the exact ISO 15552 mounting interface, G3/4 port, and M36x2 rod thread, fitting existing fixtures perfectly.
Note this 2000 mm stroke exceeds the 1500 mm standard maximum, making it a non-standard, made-to-order item requiring external guides to prevent rod bending. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. With no -S suffix, this SKU cannot take a sensor.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X2000 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X2000 Is Used
Heavy Press Ejection
Provides the 10053 N push at 0.5 MPa needed to eject large formed parts from heavy industrial presses over long distances.
Pallet Transfer
Moves heavy automated pallets across 2-meter staging zones where a 160 mm bore and long stroke are required.
Material Lift Gate
Actuates large-scale loading dock lift gates, utilizing the 9425 N pull force to manage substantial vertical loads.
Replacing the Airtac SI160 Standard Cylinder SI160X2000 with the SAI160X2000
To replace the SI160X2000, order the SAI160X2000. Confirm the ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/4 port, and the M36x2 thread. Because this lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors; add -S if sensing is needed. Sizing both ways: the 160 mm bore yields 10053 N push at 0.5 MPa (downgrade to 125 mm for 6136 N, or upgrade to 200 mm for 15708 N). A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for holding. At 2000 mm (non-standard, exceeding the 1500 mm max), external guides are mandatory to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X2000
- ✓ 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 SI160X2000 FAQ
Yes, the SI160X2000 is discontinued. The direct replacement is the SAI160X2000. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 2000 mm stroke, force, G3/4 port, and mounting interface.
The 160 mm bore uses a G3/4 port. It generates 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.
