This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X500N, 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 SI100X500N
The AirTAC Airtac SI100 Standard Cylinder SI100X500N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X500N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X500N
The AirTAC SI100X500N is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 500mm stroke. Delivering 3927N push force at 0.5MPa via a G1/2 port, it is replaced by the SAI100X500N. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke, output force, and port size, fitting existing fixtures perfectly.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This SKU lacks a magnet (-S) and cannot take a sensor, unlike CS1-B/DS1-B legacy switches. The NBR seal handles -20 to +70C, with Viton H available.

Where the Airtac SI100 Standard Cylinder SI100X500N Is Used
Heavy Stamping Press
Drives large stamping dies requiring 3927N push force at 0.5MPa, utilizing the 500mm stroke for deep-draw operations.
Automated Assembly Line
Actuates heavy industrial fixtures over a 500mm distance, requiring external guides to manage side-load on the rod.
Replacing the Airtac SI100 Standard Cylinder SI100X500N with the SAI100X500N
To replace the SI100X500N, order the SAI100X500N. Verify the ISO 15552 mounting interface, 100mm bore, 500mm stroke, G1/2 port, and NBR seal. Because this SKU lacks a magnet, it cannot accept position sensors; if sensing is needed, select an SAI100X500NS. Sizing both ways: a neighboring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore yields 6136N. For the 500mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X500N
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
