This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX700, 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 SI160BX700
The AirTAC SI160 Standard Cylinder SI160BX700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX700
The AirTAC SI160BX700 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 700 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160BX700, retaining identical mounting, force, and stroke. This specific SKU features a SUS304 stainless steel rod (-B) for corrosion resistance but lacks a magnet, so it cannot accept position sensors.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. If higher temperatures are needed, a Viton H seal option extends the range to 150 C.

Where the Airtac SI160 Standard Cylinder SI160BX700 Is Used
Heavy Machinery Forming
Drives large presses and forming tools requiring sustained 10053 N thrust at 0.5 MPa over a 700 mm travel distance.
Stainless Rod Washdown
Ideal for food or chemical washdown environments utilizing the SUS304 rod option to resist corrosion.
Replacing the Airtac SI160 Standard Cylinder SI160BX700 with the SAI160BX700
To replace the SI160BX700, order the SAI160BX700 to guarantee the exact ISO 15552 mounting interface, 700 mm stroke, G3/4 port, and M36x2 rod thread are preserved. Confirm your mounting accessory (LB, FA, or TC) and note that because this SKU lacks the -S magnet, it cannot support CS1-B or DS1-B sensors. Sizing both ways: a 200 mm bore offers more thrust, while a 125 mm bore provides 6136 N push at 0.5 MPa if you need less force. Because this is a 700 mm stroke, use external guides to prevent rod bending and side-load damage. The air cushion only decelerates the load; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX700
- ✓ 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 SI160BX700 FAQ
Yes, the SI160BX700 is discontinued. The direct replacement is the SAI160BX700, which matches the ISO 15552 mounting interface, 160 mm bore, 700 mm stroke, output force, and G3/4 port size.
It features a G3/4 port and 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 max of 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
