This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1400S, 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 SI80X1400S
The AirTAC SI80 Standard Air Cylinder SI80X1400S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1400mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1400S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1400S
The AirTAC SI80X1400S is a discontinued double-acting ISO 15552 profile cylinder with a 1400 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X1400S, matching the bore, stroke, force, and ISO 15552 mounting interface exactly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants the SI lacked.

Where the Airtac SI80 Standard Air Cylinder SI80X1400S Is Used
Long-Stroke Diversion
Pushes heavy pallets across wide transfer lines using the 1400 mm stroke and 2513 N force at 0.5 MPa.
Vertical Material Lift
Raises 128 kg loads in two-to-one margin vertical lifting rigs, relying on the G3/8 port for rapid fill.
Large Press Ejection
Ejects formed parts from heavy machinery where the 513 kgf maximum theoretical force handles stubborn parts.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1400S with the SAI80X1400S
To replace the SI80X1400S, order the SAI80X1400S keeping the ISO 15552 mounting interface, 80 mm bore, 1400 mm stroke, G3/8 port, and -S magnet for CS1-B/DS1-B switches. If you need less force, a 63 mm bore gives 1559 N [email protected]; for more, a 100 mm bore yields 3927 N. Because 1400 mm is a long stroke, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1400S
- ✓ 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 SI80X1400S FAQ
Yes, the SI80X1400S is discontinued. The direct replacement is the SAI80X1400S, which is dimensionally interchangeable per ISO 15552 with the same 80 mm bore, 1400 mm stroke, output force, G3/8 port, and mounting accessories.
The 80 mm bore provides 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, and a theoretical max of 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s, with a 36 mm adjustable air cushion at both ends.
