This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X1000-40, 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 SIJ100X1000-40
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X1000-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1000mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X1000-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X1000-40
The AirTAC SIJ100X1000-40 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a nominal 1000 mm stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable extend range of 960-1000 mm. The stop sets the end position; it is not a load lock.
This SIJ model is discontinued; the direct replacement is the SAIJ100X1000-40, matching the ISO 15552 interface, bore, force, adjust window, port and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Note: this non-magnetic SKU cannot take a switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X1000-40 Is Used
Long-Reach Forming Press
Needs field stroke tuning to dial in the exact 960-1000 mm extend contact point on long-stroke press tools without machining hard stops.
Extended Transfer Divert
Requires trimming the extend stroke by up to 40 mm on-site to align a 1000 mm transfer arm with varying pallet widths on the line.
Large Assembly Tooling
Demands precise end-position adjustment over a 1000 mm travel window for large fixture clamping where a fixed SAI stroke plus external stop is impractical.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X1000-40 with the SAIJ100X1000-40
To replace the discontinued SIJ100X1000-40, order the direct replacement SAIJ100X1000-40, reusing your existing ISO 15552 FA, LB, or TC mounting hardware. Choose the 40 mm adjust window if your end-position needs on-site tuning between 960 and 1000 mm. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; add external sensing if required. For the 1000 mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder does not hold loads on air loss; for held loads use an external rod lock or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X1000-40
- ✓ 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 SIJ100X1000-40 FAQ
Yes, the SIJ100X1000-40 is discontinued. The direct replacement is the SAIJ100X1000-40. It shares the same ISO 15552 interface, 100 mm bore, 1000 mm nominal stroke, 40 mm adjust window, G1/2 port, and mounting, while adding an upgraded SAI piston seal.
The double-acting double-rod SIJ100X1000-40 has a 40 mm adjust window, allowing you to trim the extend stroke from 1000 mm down to 960 mm on-site. The G1/2 port and 36 mm cushions match the standard SAI bore.
