This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X225-30, 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 SIJ32X225-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X225-30 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 SAIJ32X225-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-30
The AirTAC SIJ32X225-30 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ32X225-30. It uses an external stop screw to trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 195-225 mm from the 225 mm nominal maximum. The SAIJ direct keeps the exact bore, stroke, force, and mounting interface.
The SAIJ replacement upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. This SKU has no -S magnet and cannot take a sensor. The stop screw sets end position but is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-30 Is Used
Diverter Gate Positioning
Tunes the extend stroke up to 30 mm on-site to set the exact contact point of a pneumatic diverter gate without machining spacers.
Carton Flap Folding
Adjusts the end position on the fly to fold varying carton heights, using the 195-225 mm extend window for precise alignment.
Light Part Seating
Applies a safe seating force of 241 N to press lightweight components into housings, with field adjustment for different assembly depths.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-30 with the SAIJ32X225-30
To replace the SIJ32X225-30, order the SAIJ32X225-30; it is a direct swap retaining the ISO 15552 mounting dimensions and G1/8 port. Choose the 30 mm adjust window if your end-position tuning falls within 195-225 mm. Mounting options include Basic, FA, LB, and TC. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. For this 225 mm stroke, keep side-load within standard ISO 15552 limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X225-30
- ✓ 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 SIJ32X225-30 FAQ
Yes, the SIJ32X225-30 is discontinued. The direct replacement is the SAIJ32X225-30, which shares the same ISO 15552 interface, 32 mm bore, 225 mm stroke, 30 mm adjust window, and G1/8 port.
The external stop screw shortens the extend stroke by up to 30 mm, yielding a usable range of 195-225 mm. The stop sets end position and is not a load lock.
