This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X192SN, 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 SI100X192SN
The AirTAC Airtac SI100 Standard Cylinder SI100X192SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 192mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X192SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X192SN
The AirTAC SI100X192SN is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 192mm stroke. It delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa, utilizing a G1/2 air port and M20x1.5 rod thread. AirTAC replaced this legacy unit with the SAI100X192SN, a direct upgrade retaining the exact ISO 15552 mounting interface, output force, and dimensions.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This SI-SKU includes a piston magnet for CS1-B/DS1-B sensors and an NBR seal rated for -20 to +70 C; a Viton H option raises heat resistance to 150 C. Note that plain cylinders drift without live air, so explore SAIL or BSAI lock variants if load holding is required.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X192SN Is Used
Heavy-Duty Pressing
Drives large stamping and pressing operations requiring substantial thrust, delivering up to 7068 N at 0.9 MPa for secure metal forming.
Pallet Handling
Actuates heavy pallet lifts and transfer gates where the 100mm bore provides the necessary force to move loaded assemblies smoothly.
Bulk Material Diversion
Powers robust diverter arms on high-capacity conveyor lines, using adjustable air cushions to decelerate heavy loads at stroke ends.
Replacing the Airtac SI100 Standard Cylinder SI100X192SN with the SAI100X192SN
To replace the discontinued SI100X192SN, order the SAI100X192SN. Verify your ISO 15552 mounting fixtures (LB, FA, TC, etc.), the G1/2 port, and the 192mm stroke. The magnet (-S) allows for legacy CS1-B/DS1-B sensors, though the SAI family uses current AirTAC switches. If you need higher force, the neighboring 125mm bore yields 6136 N push at 0.5 MPa; if downsizing, the 80mm bore provides 2513 N. Because this is a plain double-acting cylinder, it will not hold a load without air—use an external pilot check valve or the SAIL/BSAI lock variants for secure holding. At 192mm stroke, side-load risks are low, but always ensure proper guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X192SN
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
