This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X190S, 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 SI100 Standard Cylinder SI100X190S
The AirTAC Airtac SI100 Standard Cylinder SI100X190S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 190mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X190S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X190S
The AirTAC SI100X190S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 190mm stroke. Delivering 3927 N push force at 0.5 MPa via a G1/2 port, it is replaced by the SAI100X190S. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, output force and port size. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
The SI100X190S includes a magnet for legacy CS1-B/DS1-B sensors, whereas the SAI uses current AirTAC switches. The SAI family also adds SAIL, SAIF and BSAI lock variants the SI lacked.

Where the Airtac SI100 Standard Cylinder SI100X190S Is Used
Heavy-Duty Pressing
Drives large stamping or riveting fixtures, utilizing the 5497 N push force at 0.7 MPa to seat heavy components firmly.
Logistics Diverters
Actuates heavy-duty sorting gates on high-throughput packaging lines, relying on the 36mm adjustable cushions to stop smoothly.
Replacing the Airtac SI100 Standard Cylinder SI100X190S with the SAI100X190S
To replace the SI100X190S, order the SAI100X190S. Verify your ISO 15552 mounting accessories (LB, FA, TC, etc.), the G1/2 port threads (PT/G/NPT) and the built-in magnet. This 100mm bore yields 5497 N at 0.7 MPa; if undersized, the 125mm bore offers more thrust, or drop to the 80mm bore for 3518 N at 0.7 MPa. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The 190mm stroke is below the 300mm threshold, so rod-bending side-load risks are minimal, but always guide the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X190S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X190S FAQ
Yes, the AirTAC SI100X190S is discontinued. The direct replacement is the SAI100X190S. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 190mm stroke, G1/2 port, output force and mounting interface, so it drops directly into existing fixtures.
This double-acting cylinder uses a G1/2 air port. The thrust ratings are: 3927 N push and 3681 N pull at 0.5 MPa; 5497 N push at 0.7 MPa; 7068 N push at 0.9 MPa; and a theoretical maximum of 801 kgf at 1.0 MPa.
