This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X80-10, 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 SIJ100X80-10
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10 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 SAIJ100X80-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10
The AirTAC SIJ100X80-10 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 10 mm on-site, giving a usable 70-80 mm extension out of the 80 mm nominal maximum. This 100 mm bore utilizes a G1/2 port, M20x1.5 rod thread, and 36 mm adjustable air cushions. As an end-of-life product, the direct replacement is the SAIJ100X80-10, matching the interface, force, and mounting.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet, so it cannot accept a magnetic switch, and the stop screw sets end position but is not a load lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10 Is Used
Press Fit Dialing
Fine-tune the 70-80 mm extend endpoint on-site by up to 10 mm to perfect bearing seating without machining custom spacers.
Divertor Gate Adjustment
Shift the extend stop slightly to alter a divertor arm's reach for mixed product sizes on a packaging line.
Pallet Stop Tuning
Micro-adjust the 100 mm bore extend stroke to set precise pallet positioning heights against rigid external stops.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10 with the SAIJ100X80-10
To replace the discontinued SIJ100X80-10, order the direct replacement SAIJ100X80-10, which preserves the 10 mm adjust window, 80 mm stroke, and G1/2 port. Choose the 10 mm adjust window when you need minor on-site extend tuning between 70-80 mm. Mounting interfaces (FA, LB, TC) reuse existing ISO 15552 fixtures. Because this SKU has no -S suffix, it cannot support legacy CS1-B/DS1-B sensors. For strokes at or above 300 mm, verify side-load limits to prevent guide failure. The stop screw only sets the end position; for load holding on air loss, specify an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X80-10
- ✓ 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 SIJ100X80-10 FAQ
Yes, the SIJ100X80-10 is discontinued. The direct replacement is the SAIJ100X80-10. It matches the ISO 15552 interface, 100 mm bore, 80 mm stroke, 10 mm adjust window, G1/2 port, and mounting hardware, while adding an upgraded piston seal.
The external stop screw provides a 10 mm adjust window, shortening the 80 mm nominal extend stroke down to 70 mm. The stop sets end position and is not a load lock.
