This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X110, 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 SI160X110
The AirTAC SI160 Standard Cylinder SI160X110 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 110mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X110, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X110
The AirTAC SI160X110 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 110 mm stroke, delivering a push force of 10053 N at 0.5 MPa. It is replaced by the SAI160X110 direct cylinder, which maintains the exact same interface, force, and G3/4 port. The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For high-temperature environments, Viton H seals raise the operating range to 0-150 C.
This specific SKU lacks a magnet and cannot accept position sensors. Note that a standard cylinder does not hold load on air loss; the 50 mm adjustable cushions only decelerate the piston near stroke end.

Where the Airtac SI160 Standard Cylinder SI160X110 Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring substantial thrust, utilizing the 10053 N push force at 0.5 MPa to shape heavy metal components.
Industrial Clamp Fixtures
Secures large fabricated steel structures during welding or machining, using the 9425 N pull force to maintain rigid clamping pressure.
Replacing the Airtac SI160 Standard Cylinder SI160X110 with the SAI160X110
To replace the discontinued SI160X110, order the SAI160X110. Verify your ISO 15552 mounting interface (LB, FA, CA, TC, etc.), bore, 110 mm stroke, and G3/4 port. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B switches; if sensing is needed, select an SAI model with a magnet. Sizing both ways: this bore yields 10053 N push at 0.5 MPa, while a 200 mm bore provides 15708 N. If your application requires load holding on air loss, do not rely on the cushions—use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants. Since the stroke is under 300 mm, side-load rod-bending risks are minimal, but standard guide alignment is still advised.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X110
- ✓ 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 SI160X110 FAQ
Yes, the AirTAC SI160X110 is discontinued. The direct replacement is the SAI160X110. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 160 mm bore, 110 mm stroke, output force, G3/4 port, and mounting accessories.
The bore is 160 mm with 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. It operates at 30-500 mm/s.
