This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X700-40S, 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 SIJ100X700-40S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X700-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X700-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-40S
The AirTAC SIJ100X700-40S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100mm bore and 700mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 660-700mm extension window. The direct replacement is the SAIJ100X700-40S, sharing the exact ISO 15552 mounting interface, bore, force, and adjust window.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The external stop sets end position but is not a load lock; use SAIL/BSAI variants or an external rod lock for held loads.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-40S Is Used
Variable Press Stroke
Trimming the extend stroke by up to 40mm on-site allows a 100mm bore press to accommodate varying material thicknesses without re-mounting the cylinder.
Adjustable Diverter Arm
Tuning the 660-700mm extension window lets operators alter the reach of a diverter mechanism on a conveyor line to handle different package sizes.
Custom Positioning Stop
Using the external stop screw to set a precise end position for a pallet handling actuator, providing exact 700mm or shorter maximum reach.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-40S with the SAIJ100X700-40S
To replace the discontinued SIJ100X700-40S, order the direct replacement SAIJ100X700-40S, keeping the 700mm nominal stroke, 40mm adjust window, and -S magnet. The 40mm adjust window is ideal if your end position needs 660-700mm of extend travel. Reuse FA, LB, or TC mounts via the ISO 15552 interface. Because the 700mm stroke exceeds 300mm, account for rod-bending and use external guides to manage side loads. The stop screw only sets end position; it does not lock the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X700-40S
- ✓ 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 SIJ100X700-40S FAQ
Yes, the SIJ100X700-40S is discontinued. The direct replacement is the SAIJ100X700-40S. It shares the same ISO 15552 interface, 100mm bore, 700mm stroke, 40mm adjust window, G1/2 port, and mounting options, but adds an upgraded Y-shaped piston seal.
The external stop screw provides a 40mm adjust window, allowing the extend stroke to be shortened from the 700mm maximum down to 660mm. The stop sets end position and is not a load lock.
