This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X480N, 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 SI100X480N
The AirTAC Airtac SI100 Standard Cylinder SI100X480N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 480mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X480N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X480N
The AirTAC SI100X480N is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 480mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa, peaking at 801kgf. This NBR-sealed unit uses a G1/2 port and M20x1.5 rod thread. As it lacks the -S magnet, it cannot accept position sensors.
Order the direct replacement SAI100X480N, which shares the exact ISO 15552 mounting interface, bore, stroke, force and port. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.

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 SI100X480N Is Used
Heavy Material Transfer
Drives robust pallet stops and heavy-gauge workpiece diverters on high-capacity production lines, utilizing the 5497N push force at 0.7MPa.
Pallet Positioning Gates
Actuates large loading dock gates and heavy structural shielding, where the 100mm bore provides the necessary thrust to move substantial masses reliably.
Vertical Press Dampening
Controls the descent of heavy vertical platens in assembly presses, requiring external guides for the 480mm stroke to manage rod-bending risks.
Replacing the Airtac SI100 Standard Cylinder SI100X480N with the SAI100X480N
To replace the SI100X480N, specify the SAI100X480N and confirm the ISO 15552 mounting fixture, G1/2 port (PT/G/NPT thread), and 480mm stroke. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped version if position feedback is needed. When sizing, neighbouring bores offer different force classes: an 80mm bore yields 2513N push, while a 125mm bore yields 6136N at 0.5MPa. For the 480mm stroke, use external guides to prevent rod-bending and side-load damage. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X480N
- ✓ 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 SI100X480N FAQ
Yes, the SI100X480N is discontinued. The direct replacement is the SAI100X480N. It shares the same ISO 15552 mounting interface, 100mm bore, 480mm stroke, output force, and G1/2 port, fitting existing fixtures perfectly while upgrading the piston seal.
