This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX700SH, 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 SI80 Standard Air Cylinder SI80BX700SH
The AirTAC SI80 Standard Air Cylinder SI80BX700SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX700SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX700SH
The AirTAC SI80BX700SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 700 mm stroke, SUS304 stainless steel rod, and Viton H high-temperature seals (0-150 C). Generating 2513 N push force at 0.5 MPa, it is replaced by the SAI80BX700SH. This direct upgrade maintains the exact bore, stroke, G3/8 port, and mounting interface.
The SAI replacement introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The original -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL, SAIF, and BSAI lock variants.

Where the Airtac SI80 Standard Air Cylinder SI80BX700SH Is Used
High-Temp Ejection
Uses the SUS304 rod and Viton H seals to eject hot molded parts safely in 0-150 C environments without degrading.
Long-Stroke Diversion
Leverages the 700 mm stroke to push heavy items across wide transfer lines, requiring external guides to prevent rod bending.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX700SH with the SAI80BX700SH
To replace the SI80BX700SH, order the SAI80BX700SH, confirming the ISO 15552 interface, 80 mm bore, 700 mm stroke, G3/8 port, and mounting accessories. Specify the B code for the SUS304 rod and H for the Viton high-temp seals. Because this is a 700 mm stroke, use external guides to prevent rod bending and side-load wear. Note that a plain cylinder drifts on air loss; the air cushion only decelerates near stroke end. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX700SH
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80BX700SH FAQ
Yes, the SI80BX700SH is discontinued. The direct replacement is the SAI80BX700SH. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 700 mm stroke, G3/8 port, and output force for existing fixtures.
The G3/8 port feeds a 25 mm rod. Forces are 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa. Speed is 30-800 mm/s.
