This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X430TC, 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 SI100X430TC
The AirTAC SI100 Standard Cylinder SI100X430TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 430mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X430TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X430TC
The AirTAC SI100X430TC is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 430mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X430TC, a direct upgrade retaining the exact ISO 15552 mounting interface, TC trunnion mount, stroke, and output force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For applications needing load holding, the SAI family adds SAIL and BSAI lock variants the SI lacked.

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 SAI100X430TC 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 SI100X430TC Is Used
Heavy Press Clamping
Secures large metal castings during machining operations, utilising the 5497 N push force at 0.7 MPa to hold components firmly against the fixture bed.
Pallet Dispenser Gate
Actuates the heavy release gate on automated pallet dispensers, where the TC trunnion mount accommodates the swing arc and the 430mm stroke provides full clearance.
Replacing the Airtac SI100 Standard Cylinder SI100X430TC with the SAI100X430TC
To replace the SI100X430TC, order the SAI100X430TC. Verify the ISO 15552 TC trunnion interface, 100mm bore, 430mm stroke, G1/2 port, and M20x1.5 rod thread. This non-magnet SKU cannot accept a sensor; if position detection is needed, select an SAI model with the -S suffix and use current AirTAC switches. Sizing both ways: a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while the 125mm bore yields 6136 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI variants. At 430mm stroke, use external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X430TC
- ✓ 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 SI100X430TC FAQ
Yes, the SI100X430TC is discontinued. The direct replacement is the SAI100X430TC. It shares the exact same ISO 15552 mounting interface, 100mm bore, 430mm stroke, G1/2 port, and TC mount, so it drops directly into existing fixtures.
This double-acting cylinder operates at 0.15-1.0 MPa with a G1/2 port. It generates 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 max of 801 kgf at 1.0 MPa. Speed is 30-800 mm/s.
