This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X100-10, 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 SIJ63X100-10
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X100-10 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 SAIJ63X100-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-10
The AirTAC SIJ63X100-10 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 10 mm on-site, yielding a usable 90-100 mm extend window from the 100 mm nominal maximum. The direct replacement is the SAIJ63X100-10, matching the interface, force, and mounting.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet (-S) and cannot take a switch. The stop screw sets end position but is not a lock; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-10 Is Used
Press Fit Tuning
Dial in a 90-100 mm extend for seating bearings, using the external stop to compensate for material thickness variations without reprogramming the PLC.
Transfer Diverter
Adjust the extend endpoint on-site to cleanly deflect varying package sizes onto a secondary belt without crashing into the guard.
Carton Forming Stop
Set a precise 95 mm flap-fold push, trimming the 10 mm window to accommodate different corrugated board thicknesses on the fly.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X100-10 with the SAIJ63X100-10
To replace the discontinued SIJ63X100-10, order the direct replacement SAIJ63X100-10. The 10 mm adjust window is ideal for fine-tuning the 90-100 mm extend endpoint without machining. Reuse FA, LB, or TC ISO 15552 mounts. This non-magnetic SKU cannot accept legacy CS1-B/DS1-B sensors. For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding. The stop screw sets position only; it is not a load lock, so add a pilot-operated check valve for drift prevention.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X100-10
- ✓ 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 SIJ63X100-10 FAQ
Yes, the SIJ63X100-10 is discontinued. The direct replacement is the SAIJ63X100-10. It shares the identical ISO 15552 interface, 63 mm bore, 100 mm stroke, 10 mm adjust window, G3/8 port, and mounting options, but uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw provides a 10 mm adjustment window, allowing the extend stroke to be shortened on-site from the 100 mm nominal maximum down to 90 mm. The stop sets end position and is not a load lock.
