This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X190, 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 SI80X190
The AirTAC SI80 Standard Air Cylinder SI80X190 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 190mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X190, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X190
The AirTAC SI80X190 is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, delivering 2513 N of push force at 0.5 MPa through its G3/8 port. AirTAC replaced this legacy unit with the SAI80X190, a direct alternative retaining the exact 80 mm bore, 190 mm stroke, M20x1.5 rod thread, and mounting interface.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S) and cannot accept position sensors.

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 SI80X190 Is Used
Press Fit Assembly
Drives 128 kg vertical loads to seat bearings, utilizing the 2513 N push force at 0.5 MPa for reliable press fits.
Pallet Diverting
Actuates heavy diverters along packaging lines, where the 36 mm adjustable air cushion decelerates the 190 mm stroke smoothly.
Material Lift Gates
Raises and lowers loading dock gates, requiring external pilot check valves since the standard cylinder lacks load-holding capability.
Replacing the Airtac SI80 Standard Air Cylinder SI80X190 with the SAI80X190
To replace the discontinued SI80X190, order the SAI80X190 ensuring your ISO 15552 mounting fixtures, G3/8 port, and M20x1.5 rod thread match. Because this non-magnetic SKU cannot host a sensor, add the -S suffix if you need CS1-B or DS1-B switch compatibility. Sizing both ways: the 80 mm bore yields 2513 N push at 0.5 MPa, while the adjacent 63 mm bore offers 1559 N. 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 variants for held loads. At 190 mm stroke, side-load risks are minimal, but always guide the load to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X190
- ✓ 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 SI80X190 FAQ
Yes, the SI80X190 is discontinued. The direct replacement is the SAI80X190. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 190 mm stroke, G3/8 port, and mounting accessories.
The G3/8 port bore delivers a push force of 2513 N and pull of 2268 N at 0.5 MPa. At 0.7 MPa push is 3518 N, at 0.9 MPa it is 4523 N, and the theoretical maximum is 513 kgf at 1.0 MPa.
