This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X80-30, 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 SIJ100X80-30
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X80-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 80mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X80-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-30
The AirTAC SIJ100X80-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 80 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 50-80 mm extension window. The G1/2 port and 36 mm adjustable cushions govern a 30-800 mm/s speed range. Because this SIJ series is end-of-life, the direct replacement is the SAIJ100X80-30, matching the interface, bore, force, and mounting.
The SAIJ successor retains these ratings but adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Note this SKU lacks a -S magnet and cannot accept a sensor; the stop screw sets end position but is not a load lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-30 Is Used
Press Fit Tuning
Allows operators to fine-tune the 50-80 mm extend stroke on-site for pressing bearings, ensuring precise contact without re-engineering the entire fixture.
Variable Length Diverter
Adjusts the extend stop by up to 30 mm to deflect varying package sizes on a conveyor line without needing cylinder disassembly.
Adjustable End Stop
Provides a field-configurable end position for pallet lifting or positioning rigs where the exact end-of-stroke contact point changes between product runs.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-30 with the SAIJ100X80-30
To replace the discontinued SIJ100X80-30, order the SAIJ100X80-30, which is a direct match for the ISO 15552 mounting dimensions, G1/2 port, and 30 mm adjust window. Choose the 30 mm adjust window if your application requires field tuning the extend stroke within a 50-80 mm range. Mounting options include Basic, FA, LB, and TC brackets. Because this configuration has no -S suffix, it cannot support magnetic sensing. For strokes of 300 mm or longer, verify your side-load limits to prevent excessive guide wear. The external stop sets the end position but does not hold the load on air loss; for load-holding, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X80-30
- ✓ 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 SIJ100X80-30 FAQ
Yes, the SIJ100X80-30 is discontinued. The direct replacement is the SAIJ100X80-30. It shares the same ISO 15552 interface, 100 mm bore, 80 mm stroke, 30 mm adjust window, G1/2 port, and mounting options, but features an upgraded piston seal.
The external stop screw provides a 30 mm adjust window, allowing you to trim the 80 mm nominal extend stroke down to 50 mm on-site. The stop sets end position and is not a load lock.
