This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX100, 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 SI160BX100
The AirTAC Airtac SI160 Standard Cylinder SI160BX100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX100
The AirTAC SI160BX100 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 100 mm stroke. It delivers a robust 10053 N push force at 0.5 MPa. The direct replacement is the SAI160BX100, maintaining the exact same ISO 15552 mounting interface, G3/4 port, M36x2 rod thread, and output force.
This specific SKU features a SUS304 stainless steel piston rod for corrosion resistance, but because it lacks a magnet (-S), it cannot accept position sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life.

Where the Airtac SI160 Standard Cylinder SI160BX100 Is Used
Heavy Press Operations
Generates up to 18095 N at 0.9 MPa for high-force stamping, forming, and riveting tasks in automated fabrication lines.
Pallet Lift Stations
Provides a safe vertical lift capacity of roughly 512 kg, making it ideal for raising heavy industrial pallets and structural components.
Injection Molding Extraction
The SUS304 stainless rod option excels in high-temperature, corrosive molding environments when extracting large finished parts.
Replacing the Airtac SI160 Standard Cylinder SI160BX100 with the SAI160BX100
To replace the discontinued SI160BX100, order the SAI160BX100. Confirm the ISO 15552 mounting interface, the 160 mm bore, the 100 mm stroke, and the G3/4 port (available in PT, G, or NPT). Retain your original mounting accessory and note that this non-magnetic SKU cannot support switches. If you need to scale up or down, neighboring bores (125 mm or 200 mm) alter the 0.5 MPa push force (6136 N or 15708 N respectively). Because a standard cylinder does not hold load without live air—the cushion only decelerates near stroke end—use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants for secure load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX100
- ✓ 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 SI160BX100 FAQ
Yes, the SI160BX100 is discontinued. The direct replacement is the SAI160BX100. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 100 mm stroke, G3/4 port, and mounting interface, so it fits existing fixtures perfectly.
This double-acting cylinder features a G3/4 air port and an M36x2 rod thread. The 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 maximum of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
