This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X460, 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 SI100X460
The AirTAC Airtac SI100 Standard Cylinder SI100X460 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 460mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X460, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X460
The AirTAC SI100X460 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 460mm stroke. It delivers 3927N push force at 0.5MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X460, a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, and output force.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This SKU lacks a magnet (-S) and cannot accept position sensors. For load holding, note that standard air cushions only decelerate; you need an external pilot check valve or the SAIL lock variant to prevent drift.

Where the Airtac SI100 Standard Cylinder SI100X460 Is Used
Heavy Stamping Press
Drives large platens and heavy dies requiring 3927N of push force at 0.5MPa, utilizing the 460mm stroke for deep-draw operations.
Bulk Material Diversion
Actuates large routing gates on high-capacity conveyors, moving heavy product flows with adjustable 36mm end cushions.
Replacing the Airtac SI100 Standard Cylinder SI100X460 with the SAI100X460
To replace the SI100X460, order the SAI100X460 and verify your ISO 15552 mounting interface, G1/2 port, and M20x1.5 rod thread. Because this SKU lacks a magnet, it cannot support CS1-B/DS1-B sensors; if sensing is needed, specify an SAI model with the S suffix. When sizing, a neighboring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore provides 6136N. For the 460mm stroke, use external guides to prevent rod bending and side-load damage. If the application requires load holding on air loss, select the SAIL or BSAI lock variant instead of relying on cushions.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X460
- ✓ 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 SI100X460 FAQ
Yes, the SI100X460 is discontinued. The direct replacement is the AirTAC SAI100X460. It shares the identical ISO 15552 mounting interface, 100mm bore, 460mm stroke, output force, and G1/2 port, so it fits existing fixtures directly.
This double-acting cylinder features a G1/2 air port and an M20x1.5 rod thread. It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N at 0.9MPa, and a theoretical maximum of 801kgf at 1.0MPa.
