This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X25-20, 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 SIJ32X25-20
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X25-20 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 25mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X25-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X25-20
The AirTAC SIJ32X25-20 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and 25mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 5-25mm stroke window. The direct replacement is the SAIJ32X25-20, matching the interface, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting interface for direct reuse of FA, LB, and TC brackets, and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. This non-magnet SKU cannot accept a position switch. Note that the stop screw sets the end position but is not a load lock; for held loads, use an external rod lock or the SAIL/BSAI variants.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X25-20 Is Used
Short-Stroke Clamping
Ideal for clamping small parts where the exact extend position must be trimmed on-site within a 5-25mm window to accommodate material thickness variations.
Component Seating
Useful for pressing or seating delicate components, using the adjustable stop screw to precisely limit the extend stroke and prevent over-travel damage.
Transfer Diverter
Suitable for actuating short transfer diverters or gates on a conveyor line where a 32mm bore provides adequate force and the stroke requires field adjustment.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X25-20 with the SAIJ32X25-20
To replace the discontinued SIJ32X25-20, order the direct replacement SAIJ32X25-20, which preserves the 32mm bore, 25mm nominal stroke, 20mm adjust window, and G1/8 port. Choose the 20mm adjust window if your application requires fine-tuning the extend stroke down to a 5mm minimum. Mounting options include Basic, FA, LB, and TC. Because this SKU lacks the -S suffix, it has no magnet and cannot support legacy CS1-B/DS1-B sensors. Since the 25mm stroke is below 300mm, side-load rod deflection is minimal and does not require a custom guide.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X25-20
- ✓ 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 SIJ32X25-20 FAQ
Yes, the AirTAC SIJ32X25-20 is discontinued. The direct replacement is the SAIJ32X25-20. It shares the same ISO 15552 interface, 32mm bore, 25mm stroke, 20mm adjust window, G1/8 port, and mounting options, but features an upgraded piston seal for longer life.
The external stop screw provides a 20mm adjust window, allowing you to shorten the 25mm nominal extend stroke down to 5mm on-site. The stop sets end position and is not a load lock.
