This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1070SH, 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 SI80X1070SH
The AirTAC SI80 Standard Air Cylinder SI80X1070SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1070mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1070SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1070SH
The AirTAC SI80X1070SH is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, delivering 2513 N push force at 0.5 MPa through its G3/8 port. Because this legacy SI unit is end-of-life, AirTAC supplies the SAI80X1070SH as a direct replacement. It matches the exact 80 mm bore, 1070 mm stroke, M20x1.5 rod thread, and ISO 15552 mounting interface, dropping directly into existing fixtures.
The SAI upgrade features a revised piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. This specific SI80X1070SH includes a high-temperature Viton H seal (rated for 0 to 150 C) and a magnetic piston for CS1-B/DS1-B switches.

Where the Airtac SI80 Standard Air Cylinder SI80X1070SH Is Used
Elevating Carriages
Lifts heavy vertical carriages over a 1070 mm travel, utilizing the 2513 N push force at 0.5 MPa to move loads safely with guided motion.
Pallet Diversion
Actuates large diverter arms across wide conveyor belts, requiring the long stroke and 80 mm bore thrust to push heavy pallets.
High-Tampress Forming
Drives pressing assemblies in heated environments up to 150 C, relying on the Viton H seal and 4523 N output at 0.9 MPa.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1070SH with the SAI80X1070SH
To replace the discontinued SI80X1070SH, order the SAI80X1070SH. Verify your ISO 15552 mounting accessory (LB, FA, CA, TC) and confirm the G3/8 air port. The -S denotes a magnetic piston for legacy CS1-B/DS1-B sensors, while -H specifies the Viton high-temperature seal (0-150 C). If sizing down, the 63 mm bore yields 1559 N push at 0.5 MPa; if sizing up, the 100 mm bore provides 3927 N. Because the 1070 mm stroke is long, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1070SH
- ✓ 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 SI80X1070SH FAQ
Yes, the SI80X1070SH is discontinued. The direct replacement is the SAI80X1070SH. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 1070 mm stroke, output force, G3/8 port, and mounting interface.
The bore features a G3/8 port. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa.
