This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X30-30, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X30-30
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X30-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 30mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X30-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X30-30
The AirTAC SIJ100X30-30 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 30mm on-site, yielding a usable 0-30mm extend stroke from the 30mm nominal maximum. The 100mm bore uses a G1/2 port, a 25mm rod with an M20x1.5 thread, and 36mm adjustable cushions at each end. This SKU has no -S magnet and cannot accept a magnetic switch.
The direct replacement is the SAIJ100X30-30, matching the interface, force, and port. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Note: the stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant to hold loads.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X30-30 Is Used
Short-Stroke Clamping
Provides adjustable clamping reach where the exact material thickness varies, letting operators tune the 0-30mm extend stroke on-site without changing the cylinder body.
Transfer Diverter
Acts as a diverter arm on a packaging line, using the external stop to fine-tune the extend position precisely to the conveyor edge for consistent product routing.
Bin Ejection
Ejects parts from a bin using a short 30mm stroke, with the stop screw allowing a reduced stroke to accommodate varying part sizes without bottoming out harshly.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X30-30 with the SAIJ100X30-30
To replace the discontinued SIJ100X30-30, order the SAIJ100X30-30 (insert A after the leading S). The SAIJ family retains the ISO 15552 mounting dimensions, allowing direct reuse of FA, LB, or TC brackets. The -30 adjust window allows trimming the 30mm nominal extend stroke down to 0mm on-site. Because this SKU lacks the -S magnet, it cannot support position sensing. The external stop screw only sets the end position; it does not lock the load on air loss. For held loads, specify an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X30-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X30-30 FAQ
Yes, the SIJ100X30-30 is discontinued. The direct replacement is the SAIJ100X30-30. It shares the same ISO 15552 interface, 100mm bore, 30mm stroke, 30mm adjust window, G1/2 port, and mounting options. The SAIJ upgrade features a two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw provides a 30mm adjust window, allowing you to trim the 30mm nominal extend stroke down to 0mm on-site. The stop sets end position only and is not a load lock.
