This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X610, 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 SI100X610
The AirTAC Airtac SI100 Standard Cylinder SI100X610 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 610mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X610, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X610
The AirTAC SI100X610 is a discontinued double-acting ISO 15552 profile cylinder. Delivering 3927 N push force at 0.5 MPa through a 100 mm bore, it is replaced directly by the SAI100X610. This direct successor retains the exact 610 mm stroke, G1/2 port, and ISO 15552 mounting interface for seamless fixture integration.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnet SKU cannot accept sensors; legacy CS1-B/DS1-B switches only fit the -S version.

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 SI100X610 Is Used
Heavy Material Transfer
Drives robust pallet stops and heavy-gauge workpiece diverters on high-throughput conveyor lines using its 3927 N push force.
Large Press Feed
Actuates heavy-duty blank feeding mechanisms into large forming presses, benefiting from the adjustable 36 mm end cushions.
Replacing the Airtac SI100 Standard Cylinder SI100X610 with the SAI100X610
To replace the SI100X610, order the SAI100X610, verifying the ISO 15552 mounting, G1/2 port, and 610 mm stroke. If downsizing, a 80 mm bore yields 2513 N push at 0.5 MPa; if upsizing, a 125 mm bore provides 6136 N. For load holding, note a plain cylinder drifts on air loss—the cushion only decelerates. Use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The 610 mm stroke requires external guides to prevent rod bending under side loads. The SAIF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X610
- ✓ 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 SI100X610 FAQ
Yes, the SI100X610 is discontinued. The direct replacement is the SAI100X610. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 610 mm stroke, G1/2 port, and mounting interface.
The 100 mm bore features a G1/2 port and M20x1.5 rod thread. Force output is 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.
