This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X300-75, 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 SIJ32X300-75
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X300-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X300-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-75
The AirTAC SIJ32X300-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. A 32mm bore and 12mm rod pair with a G1/8 port and M10x1.25 thread. The external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 225-300mm extension. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. This SKU lacks a -S magnet, so it cannot take a switch.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-75 Is Used
Variable Stroke Pressing
Trimming the extend stroke by up to 75mm on-site allows precise setup for light pressing tasks without machining a custom-length cylinder.
Adjustable Transfer Stops
Field-tuning the 225-300mm extension lets operators adapt pneumatic stops on a conveyor line to varying package heights quickly.
Custom Position Diverter
The external stop screw provides exact end-position control for a diverting arm, ensuring repeatable routing without re-engineering the stroke.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-75 with the SAIJ32X300-75
To replace the discontinued SIJ32X300-75, order the direct replacement SAIJ32X300-75, which preserves the G1/8 port, 27mm cushions, and ISO 15552 mounting (Basic, FA, LB, TC). Choose the 75mm adjust window if you need to trim the 300mm nominal stroke down to 225mm on-site. Because this is a 300mm stroke, ensure external guides mitigate side-load and rod-bending. This non-magnetic SKU cannot fit legacy CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X300-75
- ✓ 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 SIJ32X300-75 FAQ
Yes, the SIJ32X300-75 is discontinued. The direct replacement is the SAIJ32X300-75, which shares the same ISO 15552 interface, 32mm bore, 300mm stroke, 75mm adjust window, and G1/8 port. The SAIJ family also upgrades the piston seal to two Y-shaped one-way elements for longer life and lower start-up pressure.
The external stop screw window is 75mm, meaning the usable extend stroke is 225-300mm. The stop sets end position and is not a load lock; speed is 30-800mm/s.
