This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X350-40, 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 SIJ32 Double Rod Adjustable Cylinder SIJ32X350-40
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X350-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 350mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X350-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-40
The AirTAC SIJ32X350-40 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ32X350-40. It features a 32mm bore, G1/8 port, and a 350mm nominal stroke that you can trim the extend stroke by up to 40mm on-site (yielding a 310-350mm usable window) via an external stop screw. The stop sets the end position; it is not a load lock.
The SAIJ direct keeps the ISO 15552 mounting interface, bore, and force, but upgrades to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. This non-magnet SKU cannot take a switch. For a 350mm stroke, use external guides to prevent rod bending.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-40 Is Used
Adjustable Pin Insertion
Dialing in the exact 310-350mm extend position on-site to seat pins without bottoming out the tooling.
Variable Length Diverter
Tuning the extend stop in real-time to deflect different carton sizes moving down a packing line.
Positional Pusher Stop
Setting a precise physical end-stop for product indexing when sensorless mechanical positioning is preferred.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-40 with the SAIJ32X350-40
To replace the discontinued SIJ32X350-40, order the direct replacement SAIJ32X350-40, keeping the 40mm adjust window and 350mm nominal stroke. Choose FA, LB, or TC mounts to reuse your ISO 15552 interface. This SKU lacks the -S magnet and cannot take a sensor. At 350mm stroke, support the load externally to minimize side-load and rod bending. The external stop screw sets end position but does not lock; for load holding on air loss, use an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X350-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-40 FAQ
Yes, the SIJ32X350-40 is discontinued. The direct replacement is the SAIJ32X350-40, which shares the same ISO 15552 interface, 32mm bore, 350mm stroke, 40mm adjust window, G1/8 port, and mounting.
The external stop screw lets you trim the extend stroke by up to 40mm on-site, giving a usable 310-350mm window. The stop sets end position and is not a load lock.
