This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X800-75S, 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 SIJ100X800-75S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X800-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 800mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X800-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-75S
The AirTAC SIJ100X800-75S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable 725-800 mm window from the 800 mm nominal maximum. The 100 mm bore features a 25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, G1/2 port, and 30-800 mm/s speed. The direct replacement is the SAIJ100X800-75S, sharing the same interface, force, and port.
The SAIJ successor retains the ISO 15552 mounting footprint for direct reuse of FA, LB, and TC hardware, and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. 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 SIJ100X800-75S Is Used
Press Tooling Setup
Trimming the extend stroke by up to 75 mm on-site allows operators to fine-tune press contact distance without machining custom spacers.
Variable Length Diverter
Adjusting the extend end position dynamically accommodates different package widths on a sorting line within the 725-800 mm window.
Pallet Positioning Stop
Field-tuning the stop point ensures precise pallet placement when downstream conveyor clearances vary slightly.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-75S with the SAIJ100X800-75S
To replace the discontinued SIJ100X800-75S, order the direct replacement SAIJ100X800-75S, keeping the 75 mm adjust window and -S magnet for CS1-B/DS1-B switches (current AirTAC switches on the SAIJ). Select FA, LB, or TC mountings per ISO 15552 interface dimensions. Because the 800 mm stroke is long, account for side-load and rod-bending by adding external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X800-75S
- ✓ 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 SIJ100X800-75S FAQ
Yes, the SIJ100X800-75S is discontinued. The direct replacement is the SAIJ100X800-75S, which shares the same ISO 15552 interface, 100 mm bore, 800 mm stroke, 75 mm adjust window, G1/2 port, and mounting options.
The external stop screw provides a 75 mm adjust window, allowing the extend stroke to be shortened from 800 mm down to 725 mm. The stop sets end position only and is not a load lock.
