This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X1000-20, 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 SIJ100X1000-20
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X1000-20 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 SAIJ100X1000-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X1000-20
The AirTAC SIJ100X1000-20 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ100X1000-20. Its external stop screw lets you trim the extend stroke by up to 20mm on-site, giving a usable 980-1000mm stroke. The nominal 1000mm is the maximum. This 100mm bore uses a G1/2 port, M20x1.5 rod thread, and 36mm adjustable cushions.
The SAIJ direct keeps the same ISO 15552 mounting interface and force. It upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; for held loads use an external rod lock or the SAIL/BSAI variants. This SKU lacks a magnet (-S) and cannot take a switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X1000-20 Is Used
Long-Reach Forming Press
Needs field stroke tuning to dial the exact 980-1000mm extend position for a deep-draw die, absorbing heavy shock with the 36mm cushion.
Large Assembly Tooling
Requires trimming the extend stroke by up to 20mm on-site to set precise clamping contact on variable-width parts without re-engineering the fixture.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X1000-20 with the SAIJ100X1000-20
To replace the discontinued SIJ100X1000-20, order the SAIJ100X1000-20 direct. It retains the 100mm bore, 1000mm stroke, 20mm adjust window, G1/2 port, and FA/LB/TC mountings. The 20mm adjust window allows precise 980-1000mm extend tuning. Because the 1000mm stroke exceeds 300mm, ensure external guides to prevent rod bending and side-load damage. This non-magnetic SKU cannot accept legacy CS1-B/DS1-B sensors. For load-holding without live air, select a SAIL or BSAI lock variant instead of relying on the stop screw.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X1000-20
- ✓ 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 SIJ100X1000-20 FAQ
Yes, the SIJ100X1000-20 is discontinued. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for longer life.
The external stop screw window is 20mm, allowing you to shorten the extend stroke from 1000mm down to 980mm on-site. The stop sets end position and is not a load lock.
