This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X50-30, 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 SIJ32X50-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X50-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 50mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X50-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X50-30
The AirTAC SIJ32X50-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and G1/8 port. An external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable 20-50mm extension from the 50mm nominal maximum. The stop sets the end position but is not a load lock. The direct replacement is the SAIJ32X50-30, sharing the same interface, force, and mounting.
The SAIJ upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This non-magnet SKU lacks a -S sensor slot and cannot take a switch.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X50-30 Is Used
Light Clamping Stops
Trimming the extend stroke by up to 30mm on-site allows precise clamping of varied part thicknesses without swapping the cylinder.
Transfer Diverter Tuning
Adjust the extend end position to set the exact diverter angle for different product widths on a packaging line.
Sensor Probe Placement
Fine-tune the 20-50mm extend reach in the field to position a test probe accurately against delicate components.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X50-30 with the SAIJ32X50-30
To replace the discontinued SIJ32X50-30, order the direct replacement SAIJ32X50-30, reusing your existing FA, LB, or TC mounts. Choose the 30mm adjust window if you need on-site tuning between 20-50mm; for fixed 50mm extension, use a standard SAI. This plain cylinder cannot hold a load on air loss—the cushion only decelerates near stroke end—so add an external rod lock or SAIL/BSAI variant for held loads. For strokes >=300mm, verify side-load guidance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X50-30
- ✓ 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 SIJ32X50-30 FAQ
Yes, the SIJ32X50-30 is discontinued. The direct replacement is the SAIJ32X50-30, offering the same ISO 15552 interface, 32mm bore, 50mm stroke, G1/8 port, and mounting options.
The external stop screw provides a 30mm adjust window, allowing you to shorten the 50mm nominal extend stroke down to 20mm on-site.
