This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X80-20STC, 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 SIJ32X80-20STC
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X80-20STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X80-20STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-20STC
The AirTAC SIJ32X80-20STC is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and 80mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 60-80mm extension. The direct replacement is the SAIJ32X80-20STC, matching the bore, force, adjust window, and mount.
The SAIJ successor retains the ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal 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.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-20STC Is Used
Adjustable Clamping
Light-duty clamping fixtures needing field stroke tuning to accommodate 60-80mm material thicknesses without swapping cylinders.
Transfer Diverters
Conveyor diverting arms where the extend end position requires 20mm of on-site adjustment to hit the exact package lane.
Sensor Positioning
Pushing test probes or small parts where the 60-80mm extend stroke must be dialed in precisely to avoid overtravel.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-20STC with the SAIJ32X80-20STC
To replace the discontinued SIJ32X80-20STC, specify the direct replacement SAIJ32X80-20STC, keeping the 32mm bore, 80mm nominal stroke, 20mm adjust window, G1/8 port, and TC mount. Choose the 20mm adjust window when your extend stroke needs on-site tuning between 60-80mm. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current switches). For stroke lengths >=300mm, verify the side-load capacity to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X80-20STC
- ✓ 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 SIJ32X80-20STC FAQ
Yes, the SIJ32X80-20STC is discontinued. The direct replacement is the SAIJ32X80-20STC, offering the same ISO 15552 interface, 32mm bore, 80mm stroke, 20mm adjust window, G1/8 port, and TC mounting.
The external stop screw provides a 20mm adjust window, allowing you to trim the extend stroke from the 80mm maximum down to 60mm on-site.
