This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X570, 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 SI100X570
The AirTAC Airtac SI100 Standard Cylinder SI100X570 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 570mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X570, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X570
The AirTAC SI100X570 is a discontinued double-acting ISO 15552 profile cylinder delivering 3927 N push force at 0.5 MPa. AirTAC replaced it with the SAI100X570, a direct upgrade retaining the exact 100mm bore, 570mm stroke, G1/2 port, and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a magnet (-S), so it cannot take CS1-B/DS1-B sensors.

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 SI100X570 Is Used
Heavy Press Clamping
Provides the 5497 N force at 0.7 MPa needed to secure large metal castings during CNC machining operations.
Pallet Diverting
Extends 570mm to push heavy pallets off a high-speed main line onto a secondary packaging spur.
Replacing the Airtac SI100 Standard Cylinder SI100X570 with the SAI100X570
To replace the SI100X570, order the SAI100X570 and verify the ISO 15552 mounting interface, G1/2 port, and M20x1.5 rod thread. This non-magnet SKU cannot accept position sensors. If sizing down, the 80mm bore yields 2513 N [email protected]; sizing up to 125mm gives 6136 N. A plain cylinder drifts on air loss, so for load holding use an external pilot check valve or the SAIL/BSAI lock variants. With the 570mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X570
- ✓ 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 SI100X570 FAQ
Yes, the SI100X570 is discontinued. The direct replacement is the AirTAC SAI100X570. It shares the identical ISO 15552 mounting interface, 100mm bore, 570mm stroke, output force, and G1/2 port, fitting existing fixtures perfectly.
The G1/2 port bore delivers 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 maximum theoretical force of 801 kgf at 1.0 MPa. Speed is 30-800 mm/s.
