This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X200SN, 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 SI100X200SN
The AirTAC Airtac SI100 Standard Cylinder SI100X200SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X200SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X200SN
The AirTAC SI100X200SN is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore and 200mm stroke. Delivering 3927 N push and 3681 N pull at 0.5 MPa, it utilizes a G1/2 port and M20x1.5 rod thread. The direct replacement is the SAI100X200SN, sharing the same ISO 15552 mounting interface, bore, stroke, output force, and porting to fit existing fixtures perfectly.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This SI100X200SN unit includes a piston magnet for legacy CS1-B/DS1-B switches and an NBR seal rated for -20 to +70 C. For load holding, note that a standard cylinder drifts on air loss; use an external rod lock or the SAIL/BSAI lock variants.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X200SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X200SN Is Used
Heavy Press Clamping
Secures large metal castings during machining operations, utilizing the 3927 N push force at 0.5 MPa to hold components rigidly against the tooling bed.
Bulk Package Divert
Drives large-scale sorting arms on high-throughput packaging lines, moving heavy bulk cartons across parallel conveyor belts with reliable 200mm travel.
Replacing the Airtac SI100 Standard Cylinder SI100X200SN with the SAI100X200SN
To replace the discontinued SI100X200SN, order the SAI100X200SN direct. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G1/2 port, and the M20x1.5 rod thread. The -S denotes a piston magnet for CS1-B/DS1-B sensors, and -N specifies the NBR seal. Sizing both ways: the neighboring 80mm bore yields 2513 N push at 0.5 MPa, while the 125mm bore offers 6136 N. For any stroke >= 300 mm, add external guide rails to prevent rod bending under side loads. Because a plain cylinder does not hold load without live air, select the SAIL or BSAI lock variant, or an external pilot check valve, if drift is unacceptable.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X200SN
- ✓ 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 SI100X200SN FAQ
Yes, the SI100X200SN is discontinued. The direct replacement is the SAI100X200SN. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 100mm bore, 200mm stroke, G1/2 port, and output force to fit existing fixtures directly.
