This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X240TC, 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 SI100X240TC
The AirTAC SI100 Standard Cylinder SI100X240TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 240mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X240TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X240TC
The AirTAC SI100X240TC is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 240mm stroke. Delivering 3927N push force at 0.5MPa via a G1/2 port, it is replaced by the SAI100X240TC. This direct successor matches the TC trunnion mount, M20x1.5 thread and overall dimensions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and longevity. Note this SKU lacks a magnet (no -S), so it cannot accept CS1-B/DS1-B sensors. For high heat, Viton H seals raise limits to 150C.

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 SI100X240TC Is Used
Heavy Press Clamping
Secures large metal castings during machining operations, utilising the 3927N push force at 0.5MPa to hold components rigidly against cutting forces.
Pallet Diverting
Actuates heavy-duty routing gates on automated packaging lines, where the TC trunnion mount absorbs lateral moments during high-speed load transfers.
Replacing the Airtac SI100 Standard Cylinder SI100X240TC with the SAI100X240TC
To replace the SI100X240TC, order the SAI100X240TC to retain the exact ISO 15552 TC trunnion interface, 100mm bore, 240mm stroke and G1/2 port. This 240mm length is nonstandard (exceeding the 200mm standard increment), so verify fixture clearance. Sizing both ways: a neighbouring 80mm bore yields 2513N [email protected], while the 125mm bore gives 6136N. For load holding, note a plain cylinder drifts on air loss as cushions only decelerate; use an external pilot check valve or the SAIL/BSAI lock variants. Since stroke exceeds 200mm, ensure guide rails prevent rod bending under side loads. Rod material options include carbon steel, SUS420J2 (A) or SUS304 (B).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X240TC
- ✓ 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 SI100X240TC FAQ
Yes, the AirTAC SI100X240TC is discontinued. The direct replacement is the SAI100X240TC. It features the same ISO 15552 TC mounting interface, 100mm bore, 240mm stroke, G1/2 port and output force, fitting directly into existing fixtures.
The bore is 100mm with a G1/2 air port. Force ratings are: 3927N push and 3681N pull at 0.5MPa; 5497N push at 0.7MPa; 7068N push at 0.9MPa; and a theoretical max of 801kgf at 1.0MPa. Speed is 30-800mm/s.
