This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X360, 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 SI80X360
The AirTAC SI80 Standard Air Cylinder SI80X360 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 360mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X360, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X360
The AirTAC SI80X360 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 360mm stroke. Delivering 2513 N push force at 0.5 MPa through a G3/8 port, it is replaced by the SAI80X360. This direct successor matches the exact bore, stroke, force, port and ISO 15552 mounting interface.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. Note this SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. For load holding, the cushion only decelerates; use an external rod lock or the SAIL/BSAI variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80X360 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SI80 Standard Air Cylinder SI80X360 Is Used
Pallet Diversion
Pushes heavy pallets sideways at 2513 N push force, using the 360mm stroke to clear adjacent conveyor lanes.
Press Ejection
Ejects formed metal parts from a press bed, relying on adjustable 36mm air cushions to decelerate at stroke end.
Replacing the Airtac SI80 Standard Air Cylinder SI80X360 with the SAI80X360
To replace the SI80X360, order the SAI80X360 ensuring the ISO 15552 interface, 80mm bore, 360mm stroke, G3/8 port (PT/G/NPT) and mounting accessory match. This non-magnet SKU cannot take sensors. If sizing up or down, neighbouring bores 63 and 100 offer 1559 N and 3927 N push at 0.5 MPa. Because the 360mm stroke exceeds 300mm, use external guides to prevent rod bending and side-load damage. The air cushion only decelerates; for held loads use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X360
- ✓ 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 SI80X360 FAQ
Yes, the SI80X360 is discontinued. The direct replacement is the SAI80X360, which shares the same ISO 15552 mounting interface, 80mm bore, 360mm stroke, output force and G3/8 port.
The G3/8 port bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa.
