This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX800, 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 SI160BX800
The AirTAC SI160 Standard Cylinder SI160BX800 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX800, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX800
The AirTAC SI160BX800 is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, delivering 10053 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI160BX800. This direct upgrade maintains the exact ISO 15552 mounting interface, 800 mm stroke, G3/4 port, and output force, fitting existing fixtures seamlessly. This specific SKU features a SUS304 stainless steel rod for corrosion resistance but lacks a magnet, so it cannot accept position switches.
The SAI upgrade introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note that a plain cylinder drifts without live air; the 50 mm adjustable cushions only decelerate near stroke end. For load holding, consider the SAIL or BSAI lock variants.

Where the Airtac SI160 Standard Cylinder SI160BX800 Is Used
Heavy Machinery Forming
Drives large forming presses and heavy industrial machinery requiring up to 18095 N of thrust at 0.7 MPa, utilizing the robust 40 mm SUS304 stainless rod.
Bulk Material Diversion
Actuates heavy-duty diverter gates on bulk material conveyors, relying on the 50 mm adjustable air cushions to decelerate the 800 mm stroke smoothly.
Replacing the Airtac SI160 Standard Cylinder SI160BX800 with the SAI160BX800
To replace the discontinued SI160BX800, order the SAI160BX800. Confirm the ISO 15552 mounting interface, the 160 mm bore, 800 mm stroke, and G3/4 port (PT/G/NPT thread options). Because this SKU lacks a magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, specify an SAI160BX800S. If sizing up or down, neighboring bores are 125 mm and 200 mm. At 0.5 MPa, the 125 mm bore yields 6136 N push, while the 200 mm bore yields 15708 N. For load holding on air loss, a plain cylinder drifts; use an external rod lock, a pilot check valve, or the SAIL air-released lock and BSAI clamp-lock variants. Finally, for the 800 mm stroke, prevent rod bending by guiding the load externally to avoid side-load stress.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX800
- ✓ 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 SI160BX800 FAQ
Yes, the AirTAC SI160BX800 is discontinued. The direct replacement is the SAI160BX800. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 800 mm stroke, G3/4 port, and mounting accessories.
