This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X80-20S, 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 SIJ32X80-20S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X80-20S 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 SAIJ32X80-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-20S
The AirTAC SIJ32X80-20S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The direct replacement is the SAIJ32X80-20S, retaining the 32mm bore, 80mm nominal stroke, G1/8 port, and mounting interface. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 60-80mm extend range. The stop sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-20S Is Used
Diverter Gate Positioning
Allows field tuning of the 60-80mm extend stroke to hit diverter gates precisely without machining new hard stops.
Variable Depth Sealing Heads
Adjusts the extend end-position on-site to accommodate different carton depths using the 20mm stop screw window.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-20S with the SAIJ32X80-20S
To replace the discontinued SIJ32X80-20S, order the SAIJ32X80-20S direct; it preserves the ISO 15552 mounting dimensions, 27mm adjustable cushions, M10x1.25 rod thread, and the -S magnet. The 20mm adjust window is ideal if your exact extend length varies between 60 and 80mm on-site. Mounting choices include Basic, FA, LB, and TC. Because the 80mm stroke is under 300mm, side-load leverage is minimal. Note that a plain cylinder drifts on air loss; for load holding, select the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X80-20S
- ✓ 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 SIJ32X80-20S FAQ
Yes, the SIJ32X80-20S is discontinued. The direct replacement is the SAIJ32X80-20S, which shares the same ISO 15552 interface, 32mm bore, 80mm stroke, 20mm adjust window, G1/8 port, and mounting options.
The external stop screw offers a 20mm adjustment window, allowing the 80mm nominal extend stroke to be shortened to a minimum of 60mm on-site.
