This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X200TC, 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 SI100X200TC
The AirTAC Airtac SI100 Standard Cylinder SI100X200TC 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 SAI100X200TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X200TC
The AirTAC SI100X200TC is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 200mm stroke. It delivers 3927 N push force at 0.5 MPa via a G1/2 port. The direct replacement is the SAI100X200TC, retaining the same interface, force, and TC trunnion mount.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI variants the SI lacked. Note this SKU lacks a magnet, so it cannot take a sensor.

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 SAI100X200TC 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 SI100X200TC Is Used
Heavy-Duty Pressing
Drives large stamping or forming fixtures requiring up to 3927 N of push force at 0.5 MPa operating pressure.
Pallet Diversion
Actuates robust TC-mounted routing gates or heavy lifting arms within automated materials handling lines.
Replacing the Airtac SI100 Standard Cylinder SI100X200TC with the SAI100X200TC
To replace the SI100X200TC, order the SAI100X200TC. Verify the ISO 15552 TC trunnion mount, 100mm bore, 200mm stroke, G1/2 port, and M20x1.5 thread. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI if sensing is needed. Sizing both ways: a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while a 125mm bore yields 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 variant. Rod material options include carbon steel, SUS420J2 (A), or SUS304 (B).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X200TC
- ✓ 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 SI100X200TC FAQ
Yes, the SI100X200TC is discontinued. The direct replacement is the SAI100X200TC. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 200mm stroke, G1/2 port, TC trunnion mount, and output force, so it fits existing fixtures perfectly.
The bore is 100mm with a G1/2 air port and M20x1.5 rod thread. Forces are: 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; with a theoretical max of 801 kgf at 1.0 MPa. Speed is 30-800 mm/s.
