This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X80-75, 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 SIJ100X80-75
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X80-75 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 SAIJ100X80-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-75
The AirTAC SIJ100X80-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 75mm on-site, giving a usable 5-80mm stroke out of the 80mm nominal maximum. It features a 25mm rod, M20x1.5 thread, 36mm adjustable cushions, and a G1/2 port.
Because this model is end-of-life, the direct replacement is the SAIJ100X80-75, matching the interface, force, port, and mounting. The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this SKU lacks the -S magnet and cannot take a sensor.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-75 Is Used
Variable Depth Pressing
Allows operators to dial in the exact extend stop for seating bearings or pins without swapping the entire actuator.
Adjustable Diverter Arms
Fine-tunes the reach of a sorting gate on the fly to accommodate different package widths on the line.
Custom Forming Stops
Provides a hard mechanical end position that can be shortened on-site for carton forming or folding tasks.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-75 with the SAIJ100X80-75
To replace the discontinued SIJ100X80-75, specify SAIJ100X80-75 for an exact ISO 15552 direct. Choose the 75mm adjust window if you need to trim the 80mm nominal stroke down to a 5mm minimum extend. Mounting interfaces include Basic, FA, LB, and TC. Because this SKU has no -S suffix, it cannot accept a magnetic switch; add -S for legacy CS1-B/DS1-B sensor accuracy if needed. For strokes of 300mm or longer, verify your side-load limits to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X80-75
- ✓ 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 SIJ100X80-75 FAQ
Yes, the SIJ100X80-75 is discontinued. The direct replacement is the SAIJ100X80-75. It shares the same ISO 15552 mounting interface, 100mm bore, 80mm stroke, 75mm adjust window, G1/2 port, and force ratings, while adding an upgraded two-piece Y-shaped piston seal.
The external stop screw allows you to trim the extend stroke by up to 75mm on-site, reducing the 80mm nominal stroke to a 5mm minimum. The stop sets end position but is not a load lock.
