This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X25-10S, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 25mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X25-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10S
The AirTAC SIJ100X25-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 25 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 15-25 mm end position. The G1/2 port and 36 mm adjustable cushions govern a 30-800 mm/s speed range. Because this SIJ model is discontinued, the direct replacement is the SAIJ100X25-10S, retaining the same interface, force, and mounting.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure. Note the stop screw sets end position only; it is not a lock, so use an external rod lock or SAIL/BSAI variant for load holding.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10S Is Used
Short-Stroke Clamping
Trimming the extend stroke by up to 10 mm on-site allows precise clamping of variable thickness parts without repositioning the cylinder body.
Transfer Diverter
Adjustable end positioning accommodates different package sizes on a conveyor line, letting the 25 mm stroke actuate a diverter gate exactly where needed.
Press Fit Tuning
The external stop screw provides exact bottoming depth for light press-fit operations, ensuring consistent insertion without relying on machine frame shimming.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10S with the SAIJ100X25-10S
To replace the discontinued SIJ100X25-10S, order the direct replacement SAIJ100X25-10S, which preserves the G1/2 port, M20x1.5 rod thread, and 25 mm nominal stroke. The 10 mm adjust window is ideal for fine-tuning the 15-25 mm extend stroke without machining. Mounting interfaces include Basic, FA, LB, and TC. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches (the SAIJ uses current switches). For strokes >=300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X25-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10S FAQ
Yes, the SIJ100X25-10S is discontinued. The direct replacement is the SAIJ100X25-10S. It shares the same ISO 15552 interface, 100 mm bore, 25 mm stroke, 10 mm adjust window, G1/2 port, and mounting options, but adds an upgraded piston seal.
The external stop screw provides a 10 mm adjust window, allowing you to shorten the 25 mm extend stroke down to 15 mm on-site. The stop sets end position and is not a load lock.
