This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1700S, 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 SI80X1700S
The AirTAC SI80 Standard Air Cylinder SI80X1700S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1700S
The AirTAC SI80X1700S is a discontinued double-acting ISO 15552 profile cylinder featuring an extruded aluminum barrel. It delivers 2513 N of push force at 0.5 MPa through an 80 mm bore. This specific 1700 mm stroke exceeds the 1500 mm standard maximum, making it a non-standard, made-to-order configuration. The direct replacement is the SAI80X1700S, matching the exact bore, stroke, 513 kgf max force, G3/8 port, and ISO 15552 mounting interface.
The SAI80X1700S upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SAI family also adds SAIL, SAIF, and BSAI lock variants absent in the SI line. This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors, while the SAI replacement uses current AirTAC switches.

Where the Airtac SI80 Standard Air Cylinder SI80X1700S Is Used
Long-Stroke Material Transfer
Drives large packages across wide conveyor gaps using the 1700 mm travel, relying on the 2513 N push force to overcome carton inertia.
High-Reach Pallet Dispensing
Extends upward or outward to feed empty pallets into elevated stacking zones, requiring external guides to manage the long rod extension.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1700S with the SAI80X1700S
To replace the discontinued SI80X1700S, order the SAI80X1700S. Verify your ISO 15552 mounting interface (LB, FA, CA, TC, etc.), the G3/8 air port, and M20x1.5 rod thread. Because this 1700 mm stroke exceeds the 1500 mm standard maximum, expect a made-to-order lead time and ensure external guides are used to prevent rod bending and side-load damage over the long travel distance. For sizing alternatives, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. Note that a plain cylinder does not hold load without live air; the cushion only decelerates. For load holding on air loss, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variant. The Viton H seal option raises operating temperature to 150 C.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1700S
- ✓ 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 SI80X1700S FAQ
Yes, the SI80X1700S is discontinued. The direct replacement is the SAI80X1700S. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 1700 mm stroke, 513 kgf max force, G3/8 port, and mounting interface.
The bore is 80 mm with a G3/8 air port. At 0.5 MPa it provides 2513 N push and 2268 N pull force. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
