This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X30-30, 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 SIJ63 Double Rod Adjustable Cylinder SIJ63X30-30
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X30-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 30mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X30-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X30-30
The AirTAC SIJ63X30-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 0-30 mm extend window from the 30 mm nominal maximum.
Because SIJ is end-of-life, the direct replacement is the SAIJ63X30-30, matching the ISO 15552 interface, force, and mountings. The SAIJ upgrade uses two Y-shaped one-way piston seals for low start-up pressure and long life. Note this SKU lacks a -S magnet and cannot take a switch; the stop sets end position but is not a load lock.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X30-30 Is Used
Short-Stroke Clamping
Adjustable 0-30 mm extend window lets operators dial in exact clamping contact on variable parts without swapping cylinders.
Transfer Diverter
Field-trim the extend stroke by up to 30 mm to fine-tune a diverter gate position on the fly for changing package widths.
Product Stopper
Set a precise end-stop for incoming goods; the 30 mm adjust window accommodates product height variations on the line.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X30-30 with the SAIJ63X30-30
To replace the SIJ63X30-30, order the direct replacement SAIJ63X30-30, reusing your existing FA, LB, or TC ISO 15552 mounts. Choose the 30 mm adjust window when you need field stroke tuning rather than a fixed stop. As this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. The external stop sets end position but is not a lock; for load holding use SAIL/BSAI or an external rod lock. For strokes over 300 mm, verify side-load limits.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X30-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X30-30 FAQ
Yes, the SIJ63X30-30 is discontinued. The direct replacement is the SAIJ63X30-30. It shares the same ISO 15552 interface, 63 mm bore, 30 mm stroke, 30 mm adjust window, G3/8 port, and mounting options. The SAIJ features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw provides a 30 mm adjust window, allowing you to shorten the extend stroke by up to 30 mm on-site. The stop sets end position only; it is not a load lock.
