This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X180H, 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 SI100X180H
The AirTAC SI100 Standard Cylinder SI100X180H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 180mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X180H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X180H
The AirTAC SI100X180H is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 180mm stroke. Designed for high-temperature environments, it features a Viton H seal (0 to 150 C) and delivers 3927 N push force at 0.5 MPa. The direct replacement is the SAI100X180H, matching the G1/2 port, M20x1.5 rod thread, and 36mm cushions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. Note this SKU lacks a magnet (-S) so it cannot accept CS1-B/DS1-B sensors.

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 SI100X180H Is Used
High-Tactile Pressing
Applies 5497 N at 0.7 MPa for seating bearings or forming light panels in hot environments up to 150 C using the Viton H seal.
Heavy Product Diversion
Pushes large pallets or totes on a packaging line, utilizing the 180mm stroke and 3927 N push force at 0.5 MPa.
Replacing the Airtac SI100 Standard Cylinder SI100X180H with the SAI100X180H
To replace the SI100X180H, order the SAI100X180H and verify the ISO 15552 mounting interface, G1/2 port, and 180mm stroke. Because this is a non-magnetic SKU, position sensing is impossible; if needed, switch to an -S SAI variant for CS1-B/DS1-B compatibility. The Viton H seal handles 0-150 C. For sizing, a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while the 125mm bore hits 6136 N. Remember, a plain cylinder drifts on air loss—the cushion only decelerates. For secure holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 180mm stroke, rod bending stress is low, but always guide the load to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X180H
- ✓ 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 SI100X180H FAQ
Yes, the AirTAC SI100X180H is discontinued. The direct replacement is the SAI100X180H. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 180mm stroke, G1/2 port, and mounting fixtures.
This 100mm bore cylinder uses a G1/2 air port. It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa.
