This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X700-30S, 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 SIJ100X700-30S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X700-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X700-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-30S
The AirTAC SIJ100X700-30S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 670-700 mm window from the 700 mm nominal maximum. The direct replacement is the SAIJ100X700-30S, retaining the same interface, force, and adjustability.
The SAIJ successor introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-30S Is Used
Press Fit Tuning
Pin insertion tasks requiring exact 670-700 mm extend endpoints to accommodate material thickness variations without re-engineering the entire fixture.
Divert Stop Adjustment
Package sorting lines where the external stop screw trims the actuator stroke by up to 30 mm to handle varying box sizes on the fly.
Pallet Positioning
End-of-line pallet handling needing precise pusher positioning, allowing operators to dial in the final 30 mm of travel for alignment.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-30S with the SAIJ100X700-30S
To replace the discontinued SIJ100X700-30S, order the SAIJ100X700-30S direct, which preserves the ISO 15552 mounting dimensions, G1/2 port, and 30 mm adjust window. Choose the 30 mm adjust window if you need precise 670-700 mm extend tuning; for fixed stops, a standard SAI avoids the external screw. Mounting options include FA, LB, and TC brackets. The -S magnet enables position sensing, though the SAIJ uses current AirTAC switches over legacy CS1-B/DS1-B. Because the 700 mm stroke exceeds 300 mm, verify side-load limits and add external guides to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X700-30S
- ✓ 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 SIJ100X700-30S FAQ
Yes, the SIJ100X700-30S is discontinued. The direct replacement is the SAIJ100X700-30S. It shares the identical ISO 15552 interface, 100 mm bore, 700 mm stroke, 30 mm adjust window, G1/2 port, and mounting options, while adding an upgraded piston seal.
The external stop screw provides a 30 mm trim window, making the usable extend stroke 670-700 mm. Speed is 30-800 mm/s, and the stop sets end position only—it is not a load lock.
