This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X80-30, 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 SIJ63X80-30
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X80-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X80-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X80-30
The AirTAC SIJ63X80-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. It features a 63mm bore, G3/8 port, and an external stop screw that lets you trim the extend stroke by up to 30mm on-site (usable extend range 50-80mm). The nominal 80mm stroke is the maximum.
The direct replacement is the SAIJ63X80-30, retaining the same interface, force, and porting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X80-30 Is Used
Variable Pitch Pushing
Tuning the extend stroke by up to 30mm on-site to push parts of varying widths into a machining station without swapping the cylinder.
Adjustable Diverter Arm
Setting a precise 50-80mm extend endpoint to deflect different package sizes on a conveyor line, allowing rapid field adjustments.
Variable Depth Stopping
Acting as an end-stop in a palletizing cell where the external screw trims the 80mm stroke to match varying product depths on the fly.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X80-30 with the SAIJ63X80-30
To replace this discontinued SIJ63X80-30, order the direct replacement SAIJ63X80-30, reusing your existing FA, LB, or TC ISO 15552 mounts. The 30mm adjust window lets you tune the extend stroke down to 50mm on-site. This non-magnetic SKU cannot take a switch (unlike the -S variant). For stroke lengths >=300mm, verify side-load guide tolerances. The stop screw is not a lock; for held loads use SAIL/BSAI or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X80-30
- ✓ 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 SIJ63X80-30 FAQ
Yes, the SIJ63X80-30 is discontinued. The direct replacement is the SAIJ63X80-30, which shares the same ISO 15552 interface, 63mm bore, 80mm stroke, G3/8 port, and mounting options. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw offers a 30mm adjust window, shortening the extend stroke from the 80mm maximum down to 50mm. The stop sets position only; it is not a load lock.
