This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X2000S, 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 SI160X2000S
The AirTAC Airtac SI160 Standard Cylinder SI160X2000S 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 SAI160X2000S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X2000S
The AirTAC SI160X2000S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 2000 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. Because this stroke exceeds the 1500 mm standard maximum, it was produced as a non-standard made-to-order unit. AirTAC replaced this EOL model with the SAI160X2000S direct upgrade, retaining the exact ISO 15552 mounting interface, M36x2 thread, and 2050 kgf max force.
The SAI160X2000S features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also introduces lock variants (SAIL, BSAI) absent in the SI line. The -S magnet supports legacy CS1-B/DS1-B sensors, while a Viton H seal option raises operating temps to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X2000S Is Used
Heavy Material Transfer
Drives large fabricated components along 2000 mm strokes in automated fabrication lines, utilizing the 10053 N push force at 0.5 MPa for robust horizontal positioning.
Palletizer Actuation
Executes high-tonnage lifting and pushing tasks in end-of-line packaging, where the 160 mm bore and adjustable 50 mm cushions manage heavy palletized loads smoothly.
Press Ejection Systems
Provides the extended reach and 14074 N thrust at 0.7 MPa needed to eject dense parts from large industrial presses, relying on external guides to stabilize the long rod.
Replacing the Airtac SI160 Standard Cylinder SI160X2000S with the SAI160X2000S
To replace the SI160X2000S, order the SAI160X2000S. Confirm the ISO 15552 mounting interface, the G3/4 port, the M36x2 rod thread, and the -S magnet for current AirTAC switches. Sizing checks: a 200 mm bore offers 15708 N push at 0.5 MPa, while a 125 mm bore gives 6136 N. Because the 2000 mm stroke exceeds the 1500 mm standard, it is non-standard and requires external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X2000S
- ✓ 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 SI160X2000S FAQ
Yes, the SI160X2000S is discontinued. The direct replacement is the SAI160X2000S. It is dimensionally interchangeable per ISO 15552, maintaining the same 160 mm bore, 2000 mm stroke, G3/4 port, and mounting interface.
At 0.5 MPa it provides 10053 N push and 9425 N pull force. At 0.7 MPa push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical max force is 2050 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-500 mm/s, and it uses a G3/4 port.
