This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X100-100S, 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 SIJ63X100-100S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X100-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X100-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-100S
The AirTAC SIJ63X100-100S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 100mm on-site, giving a usable 0-100mm extend out of the 100mm nominal maximum. Because the stop screw sets the end position, it is not a load lock.
As SIJ is end-of-life, the direct replacement is the SAIJ63X100-100S, retaining the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure and longer life. This -S model includes a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-100S Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to set precise drilling depths for different material thicknesses without changing the cylinder.
Adjustable Pusher Diverter
Tunes the extend stroke by up to 100mm to accommodate varying package widths on a packaging line diverter.
Tiered Pallet Stops
Sets different end-stop positions for varying pallet heights, allowing quick field stroke tuning for mixed loads.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-100S with the SAIJ63X100-100S
To replace the discontinued SIJ63X100-100S, order the direct replacement SAIJ63X100-100S, which keeps the 100mm adjust window and G3/8 port. Reuse your FA, LB, or TC ISO 15552 mounts directly. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; a no-S variant omits this. For strokes of 300mm or longer, verify side-load limits to prevent guide wear. Remember, the stop screw sets end position but does not hold loads on air loss; for held loads use SAIL/BSAI or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X100-100S
- ✓ 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 SIJ63X100-100S FAQ
Yes, the SIJ63X100-100S is discontinued. The direct replacement is the SAIJ63X100-100S. It shares the same ISO 15552 interface, 63mm bore, 100mm stroke, 100mm adjust window, G3/8 port, and mounting, but features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw window is 100mm, allowing you to trim the extend stroke by up to 100mm on-site. The stop sets end position but is not a load lock; use an external rod lock for held loads.
