This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X250-10, 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 SIJ100X250-10
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X250-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 250mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X250-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X250-10
The AirTAC SIJ100X250-10 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, yielding a usable 240-250 mm extend out of the 250 mm nominal maximum. The direct replacement is the SAIJ100X250-10, matching the G1/2 port, M20x1.5 rod thread, and 36 mm cushions.
The SAIJ successor retains the ISO 15552 mounting interface so your FA, LB, and TC brackets reuse directly, and it upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Because this SKU lacks the -S magnet, it cannot accept a magnetic switch. Note the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X250-10 Is Used
Press Fit Tuning
Final press-in depth requires micro-adjustments on the floor; the 10 mm stop window lets operators trim the 250 mm extend stroke precisely without changing the fixture.
Diverter Gate Positioning
A sorting gate needs slight extend length variations to handle different carton sizes, using the external stop screw to set the exact 240-250 mm reach.
Sealing Head Clearance
Adjustable end-positioning accommodates varying package heights on a sealing line, allowing rapid 10 mm stroke reductions to prevent crushing taller boxes.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X250-10 with the SAIJ100X250-10
To replace the discontinued SIJ100X250-10, order the exact direct replacement SAIJ100X250-10. Choose the 10 mm adjust window when you only need minor end-position tuning (240-250 mm extend). Reuse your existing FA, LB, or TC ISO 15552 mounts. As this SKU has no -S suffix, it cannot host a magnetic switch; add -S for legacy CS1-B/DS1-B sensing. For strokes at or above 300 mm, verify your side-load limits to prevent guide wear. The external stop screw merely sets the end position and does not lock the load; for held loads use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X250-10
- ✓ 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 SIJ100X250-10 FAQ
Yes, the SIJ100X250-10 is discontinued. The direct replacement is the SAIJ100X250-10. It matches the 100 mm bore, 250 mm stroke, 10 mm adjust window, G1/2 port, and ISO 15552 mounting interface, while upgrading the piston seal to two Y-shaped one-way elements for longer life.
The external stop screw provides a 10 mm adjust window, allowing you to trim the extend stroke from 250 mm down to 240 mm on-site. The stop sets end position only and does not lock the load.
