This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X450-10, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X450-10
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X450-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 450mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X450-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X450-10
The AirTAC SIJ100X450-10 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. A G1/2 port and 25mm rod frame a 450mm nominal extend stroke that an external stop screw can trim by up to 10mm on-site, yielding a 440-450mm usable window. The stop sets end position only—it is not a load lock.
The direct replacement is the SAIJ100X450-10, preserving the ISO 15552 mounting interface, bore, stroke, and force. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note: this non-magnetic SKU cannot take a switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X450-10 Is Used
Press Fit Tuning
Micro-adjust the 440-450mm extend end-position on-site to perfect a bearing press fit without re-shimming mechanical hard stops.
Transfer Diverter
Fine-tune the actuator reach on a packaging line to accommodate slight product width variations at the 450mm stroke length.
Pallet Stop Gate
Dial in the exact gate drop height for mixed pallet sizes, using the 10mm external stop to set the precise extend endpoint.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X450-10 with the SAIJ100X450-10
To replace the discontinued SIJ100X450-10, order the direct replacement SAIJ100X450-10 to reuse the existing ISO 15552 FA, LB, or TC mounts without machining. Choose the 10mm adjust window if you need micro-trimming of the extend stroke. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch for position sensing. For the 450mm stroke, use external guides to prevent rod bending and side-load wear. The stop screw sets end position only; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X450-10
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
