This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X200STC, 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 SI100X200STC
The AirTAC Airtac SI100 Standard Cylinder SI100X200STC 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 SAI100X200STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X200STC
The AirTAC SI100X200STC is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 200mm stroke, delivering 3927 N push force at 0.5 MPa. It is replaced directly by the SAI100X200STC. This direct successor shares the exact ISO 15552 mounting dimensions, G1/2 port, and M20x1.5 rod thread, fitting existing TC trunnion fixtures seamlessly.
The SAI upgrade features a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The original SI-SKU includes a magnet for CS1-B/DS1-B sensors, while the SAI family adds SAIL lock and BSAI clamp variants absent in the SI line.

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 SAI100X200STC 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 SI100X200STC Is Used
Heavy-Duty Pressing
Drives large stamping or forming dies requiring substantial thrust, utilizing the 3927 N push force at 0.5 MPa to seat components firmly.
Bulk Material Diversion
Actuates large-scale flow gates or diverters on high-capacity conveyors, moving heavy product streams reliably via TC trunnion mounting.
Replacing the Airtac SI100 Standard Cylinder SI100X200STC with the SAI100X200STC
To replace the SI100X200STC, order the SAI100X200STC. Confirm the ISO 15552 interface, 100mm bore, 200mm stroke, G1/2 port, and TC trunnion mounting. The -S magnet equates to legacy CS1-B/DS1-B sensors; the SAI replacement uses current AirTAC switches. Sizing both ways: a neighboring 80mm bore yields 2513 N push at 0.5 MPa, while a 125mm bore yields 6136 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants. Rod material options include carbon steel, SUS420J2, or SUS304.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X200STC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
