This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX195, 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 SI80AX195
The AirTAC SI80 Standard Air Cylinder SI80AX195 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 195mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX195, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX195
The AirTAC SI80AX195 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 195mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, uses a G3/8 port, and features a SUS420J2 stainless steel rod (A suffix) for corrosion resistance. Because this SKU lacks the -S magnet, it cannot accept position switches.
You must replace it with the direct replacement SAI80AX195. It shares the exact ISO 15552 mounting interface, bore, stroke, force, and port. The SAI upgrade features a two-piece Y-shaped piston seal for low start-up pressure and long life.

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 SI80AX195 Is Used
Stainless Rod Press
Ideal for moderate pressing tasks using the 2513N push force, where the SUS420J2 rod resists moisture and coolant.
Material Diversion
Drives heavy diverters or gates on production lines, utilizing the 128kg vertical lift capacity safely.
Pallet Lift Assist
Provides robust lifting force for lower-tier pallet handling or fixture elevation without requiring live load holding.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX195 with the SAI80AX195
To replace the SI80AX195, order the SAI80AX195. Confirm the ISO 15552 mounting interface, 80mm bore, 195mm stroke, G3/8 port, and your specific mounting accessory (LB, FA, TC, etc.). This unit has no -S magnet, so it cannot support legacy CS1-B/DS1-B sensors; order an -S variant if sensing is needed. For sizing, the 80mm bore yields 2513N push at 0.5MPa; dropping to a 63mm bore gives 1559N, while stepping up to 100mm gives 3927N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for held loads. The 195mm stroke is short, so side-load rod-bending is minimal, but always guide the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX195
- ✓ 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 SI80AX195 FAQ
Yes, the SI80AX195 is discontinued. The direct replacement is the SAI80AX195. It is dimensionally interchangeable per ISO 15552, matching the 80mm bore, 195mm stroke, G3/8 port, and mounting hardware exactly.
The bore is 80mm with a G3/8 port. It generates 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical max of 513kgf at 1.0MPa. Speed is 30-800mm/s.
