This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X100-30S, 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 SIJ100X100-30S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X100-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X100-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-30S
The AirTAC SIJ100X100-30S 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 30 mm on-site, yielding a usable 70-100 mm extension out of the 100 mm nominal maximum. It features a G1/2 port, a 25 mm rod, and 36 mm adjustable air cushions.
The direct replacement is the SAIJ100X100-30S, matching the bore, stroke, force, and ISO 15552 mounting interface. The SAIJ upgrade introduces a two-piece Y-shaped one-way piston seal for lower start-up pressure and longer life. Note the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 70-100 mm extend position for inserting bearings without machining fixed stop spacers.
Variable Length Diverter
Adjusts the extend stroke on-site to accommodate different package sizes on a sorting line without changing the cylinder.
Adjustable Sealing Head
Provides a 30 mm trim window to fine-tune the extend end position for carton sealing across varying flap thicknesses.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-30S with the SAIJ100X100-30S
To replace the discontinued SIJ100X100-30S, order the direct replacement SAIJ100X100-30S, which retains the G1/2 port, 25 mm rod, and ISO 15552 dimensions. Choose the 30 mm adjust window if your application requires field tuning the extend stroke between 70 and 100 mm; the SAIJ is preferable to a fixed SAI with an external stop because it cleanly integrates the stroke limitation without adding external hardware. Mounting options include FA, LB, and TC brackets. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For strokes at or above 300 mm, verify side-load limits to prevent guide wear. The stop screw sets end position and does not hold load on air loss; for held loads use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X100-30S
- ✓ 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 SIJ100X100-30S FAQ
Yes, the SIJ100X100-30S is discontinued. The direct replacement is the SAIJ100X100-30S. It shares the same ISO 15552 interface, 100 mm bore, 100 mm stroke, 30 mm adjust window, G1/2 port, and mounting options. The SAIJ features an upgraded two-piece Y-shaped piston seal for longer life.
The external stop screw provides a 30 mm adjust window, allowing the extend stroke to be shortened from the 100 mm nominal maximum down to 70 mm on-site. The stop sets end position only and does not lock the load.
