This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X225-40, 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 SIJ32X225-40
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X225-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 225mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X225-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-40
The AirTAC SIJ32X225-40 is a discontinued double-acting, double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 225 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, giving a usable extend range of 185-225 mm. The stop screw strictly sets the end position; it is not a load lock, and a plain cylinder cannot hold a load on air loss. This SKU has no magnet (-S omitted), so it cannot accept a magnetic switch. The fixed bore port is G1/8.
The direct replacement is the SAIJ32X225-40, retaining the same 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.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-40 Is Used
Light-Actuation Assembly
Tuning the extend endpoint on-site for a 32 mm bore actuator positioning light parts, using the 40 mm adjust window to dial in exact contact without re-plumbing.
Package Diverter Stroke Trim
Adjusting the extend stroke from 225 mm down to 185 mm to deflect varying carton widths on a line, setting the external stop screw to match product profiles.
Bin Pusher Calibration
Field-tuning the push endpoint for a storage bin ejector where the exact eject distance varies by container depth, relying on the 40 mm trim window.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-40 with the SAIJ32X225-40
To replace the discontinued SIJ32X225-40, order the SAIJ32X225-40 for an exact ISO 15552 direct fit. The 40 mm adjust window is ideal if your extend stroke needs on-site tuning between 185 and 225 mm. Mounting options include Basic, FA, LB, and TC brackets. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; confirm if sensing is required. For stroke lengths of 300 mm or more, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X225-40
- ✓ 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 SIJ32X225-40 FAQ
Yes, the SIJ32X225-40 is discontinued. The direct replacement is the SAIJ32X225-40, which shares the identical ISO 15552 interface, 225 mm stroke, 40 mm adjust window, G1/8 port, and mounting options. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw allows you to shorten the extend stroke by up to 40 mm on-site, yielding a usable extend range of 185-225 mm. The stop sets end position only; it is not a load lock.
