This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X200STC, 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 SI160X200STC
The AirTAC SI160 Standard Cylinder SI160X200STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X200STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X200STC
The AirTAC SI160X200STC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 200 mm stroke, delivering 10053 N push force at 0.5 MPa. It features a G3/4 port, M36x2 rod thread, and 50 mm adjustable air cushions. AirTAC replaced this legacy unit with the SAI160X200STC, a direct upgrade sharing the exact ISO 15552 mounting interface, TC trunnion mount, and output force.
The SAI replacement upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and extended life. For load holding, note that a standard cylinder drifts on air loss—the cushion only decelerates. Use an external rod lock or the SAIL/BSAI lock variants.

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 SAI160X200STC 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 SI160X200STC Is Used
Heavy Press Forming
Ideal for high-tonnage pressing and stamping operations where the 10053 N push force at 0.5 MPa is required to form heavy-gauge materials.
Large Clamp Fixtures
Secures large fabricated components in welding and machining fixtures, utilizing the TC trunnion mount to accommodate pivoting load angles.
Replacing the Airtac SI160 Standard Cylinder SI160X200STC with the SAI160X200STC
To replace the SI160X200STC, order the SAI160X200STC. Verify the ISO 15552 TC trunnion mounting interface, 200 mm stroke, G3/4 port, and the -S magnet for CS1-B/DS1-B legacy sensors (the SAI uses current AirTAC switches). Sizing context: the 160 mm bore yields 10053 N push at 0.5 MPa. If downsizing, a 125 mm bore provides 6136 N; if upsizing, a 200 mm bore offers 15708 N. Because the 200 mm stroke is under the 300 mm threshold, severe rod-bending side loads are less critical here, but always guide the load. For applications requiring load holding on air loss, select the SAIL or BSAI lock variant, or add a pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X200STC
- ✓ 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 SI160X200STC FAQ
Yes, the SI160X200STC is discontinued. The direct replacement is the SAI160X200STC. It shares the same ISO 15552 mounting interface, 160 mm bore, 200 mm stroke, G3/4 port, and force ratings, fitting directly into existing TC trunnion fixtures.
The 160 mm bore delivers 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. Operating speed is 30-500 mm/s.
