This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X700-75, 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 SIJ100X700-75
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X700-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75
The AirTAC SIJ100X700-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100mm bore and 700mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, giving a usable 625-700mm window. The direct replacement is the SAIJ100X700-75, matching the interface, force, and mounting.
The SAIJ successor retains the adjustable 36mm cushions and adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet and cannot take a sensor. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75 Is Used
Variable Press Stroke
Allows on-site extend tuning up to 75mm to accommodate material thickness variations without re-engineering the press fixture.
Adjustable Diverter
Fine-tunes the extend position on a sorting line to handle varying package sizes on the fly, ensuring accurate routing.
Pallet Positioning
Trims the extend stroke to adapt to different pallet depths or load protrusions before the final push-off action.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75 with the SAIJ100X700-75
To replace the discontinued SIJ100X700-75, order the direct replacement SAIJ100X700-75, keeping the exact 700mm nominal stroke and 75mm adjust window. Choose your mounting from Basic, FA, LB, or TC options. Because this SKU has no -S suffix, it lacks a magnet and cannot support legacy CS1-B/DS1-B sensors. Finally, at 700mm stroke, the 25mm rod is susceptible to bending; ensure external guides carry side loads to prevent rod damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X700-75
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75 FAQ
Yes, the SIJ100X700-75 is discontinued. The direct replacement is the SAIJ100X700-75, offering the same ISO 15552 interface, 700mm stroke, 75mm adjust window, and G1/2 port.
The external stop screw provides a -75mm adjust window, making the usable extend stroke 625-700mm. The stop sets end position only and is not a load lock.
