This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X250-100, 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 SIJ32X250-100
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X250-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 250mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X250-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-100
The AirTAC SIJ32X250-100 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 250 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 150-250 mm extension.
Because the SIJ line is end-of-life, the direct replacement is the SAIJ32X250-100, matching the ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet and cannot take a sensor.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-100 Is Used
Variable Pitch Push Stations
Dialing in the extend stroke by up to 100 mm on-site allows a single 32 mm bore cylinder to push parts at varying pitches without swapping the whole ISO 15552 body.
Adjustable Transfer Stops
Trimming the 250 mm maximum stroke down to 150 mm lets operators reposition a conveyor stop block precisely for different package sizes on the fly.
Prototype Forming Strokes
The external stop screw provides a hard mechanical end position for light pressing tasks, enabling safe incremental depth adjustments during prototype tooling setup.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-100 with the SAIJ32X250-100
To replace the discontinued SIJ32X250-100, order the direct replacement SAIJ32X250-100, retaining your existing FA, LB, or TC ISO 15552 mounts. Choose the 100 mm adjust window if you need to trim the 250 mm nominal extend down to a 150 mm minimum on-site. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For stroke lengths of 300 mm or more, verify your side-load limits to prevent excessive rod wear. The external stop screw sets the end position but is not a lock; for load holding without live air, use an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X250-100
- ✓ 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 SIJ32X250-100 FAQ
Yes, the AirTAC SIJ32X250-100 is discontinued. The direct replacement is the SAIJ32X250-100, which shares the identical ISO 15552 interface, 32 mm bore, 250 mm stroke, 100 mm adjust window, G1/8 port, and mounting options. The SAIJ family also uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the 250 mm nominal extend stroke down to 150 mm on-site. This stop sets the end position but is not a load lock.
