This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X150-20, 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 SIJ32 Double Rod Adjustable Cylinder SIJ32X150-20
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X150-20 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 150mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X150-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-20
The AirTAC SIJ32X150-20 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The direct replacement is the SAIJ32X150-20, matching the 32mm bore, 150mm nominal stroke, G1/8 port, and 27mm adjustable cushion. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 130-150mm forward travel; this stop sets the end position but is not a load lock.
The SAIJ upgrade uses an improved two-piece Y-shaped piston seal for low start-up pressure and long life. This non-magnet SKU cannot accept a sensor.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-20 Is Used
Diverter Gate Positioning
Trimming the 150mm extend stroke by up to 20mm on-site allows precise alignment of diverter gates without machining spacers.
Variable Format Sealing Jaws
Adjust the forward stroke within the 130-150mm window to accommodate different carton depths on a packaging line.
Light-Duty Part Ejection
Dial in the ejection distance for delicate 32mm bore applications, ensuring parts clear the mold without striking the cabinet.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-20 with the SAIJ32X150-20
To replace the discontinued SIJ32X150-20, order the direct replacement SAIJ32X150-20, reusing your existing ISO 15552 FA, LB, or TC mounts. Choose the 20mm adjust window if your end-position needs fine-tuning within a 130-150mm range. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For strokes of 300mm or longer, verify side-load limits to prevent guide wear. Note that air cushions only decelerate near stroke end; for load holding on air loss, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X150-20
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
