This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X225-20, 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 SIJ32X225-20
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X225-20 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 SAIJ32X225-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-20
The AirTAC SIJ32X225-20 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and 225mm maximum extend. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 205-225mm window. This SIJ model is discontinued; the direct replacement is the SAIJ32X225-20, retaining the same interface, force, and adjust window.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The external stop sets end position but is not a load lock; on air loss the piston drifts. For held loads use an external rod lock or the SAIL/BSAI lock variants.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-20 Is Used
Actuator End-Position Tuning
Allows operators to dial in the exact extend endpoint within a 205-225mm window on-site, removing the need to physically swap cylinder bodies for minor length corrections.
Sorting Diverter Calibration
Provides adjustable reach for a pneumatic diverter arm, letting maintenance fine-tune the push distance by up to 20mm to accommodate varying package profiles.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X225-20 with the SAIJ32X225-20
To replace the discontinued SIJ32X225-20, order the direct replacement SAIJ32X225-20, keeping the 32mm bore, 225mm stroke, 20mm adjust window, and G1/8 port. Choose the 20mm adjust window if your field tuning requires trimming the extend stroke by up to 20mm. Mounting options include FA, LB, and TC brackets. This SKU lacks the -S suffix, so it has no magnet and cannot take a magnetic switch. For strokes of 300mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X225-20
- ✓ 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 SIJ32X225-20 FAQ
Yes, the AirTAC SIJ32X225-20 is discontinued. The direct replacement is the SAIJ32X225-20, which shares the identical ISO 15552 interface, 32mm bore, 225mm stroke, 20mm adjust window, G1/8 port, and mounting options.
The external stop screw provides a 20mm adjust window, allowing the extend stroke to be shortened from the 225mm maximum down to 205mm. The stop sets end position and is not a load lock.
