This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X700-30, 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.

The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X700-30, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X700-30 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. 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 SAIJ80X700-30, matching the interface, bore, force, and mounting.
The SAIJ upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. The stop screw sets the end position but is not a load lock; use SAIL or BSAI variants for held loads. This non-magnet SKU cannot take a switch.

The SAIJ80X700-30 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Adjust the 30 mm stop window to fine-tune the divert arm reach for varying package widths without repositioning the G3/8 ported cylinder.
Set a precise mechanical end-stop for pallet feeds, leveraging the 128 kg vertical lift capacity while ensuring external guides handle the 700 mm stroke.
To replace the discontinued SIJ80X700-30, use the direct replacement SAIJ80X700-30. The 30 mm adjust window is ideal for final mechanical timing without machining spacers. Reuse FA, LB, or TC mounts via the ISO 15552 interface. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For the 700 mm stroke, use external guides to prevent rod bending and side-load damage. Remember the stop screw sets end position but is not a lock; drifting occurs on air loss.
Replacement checklist
Yes, the SIJ80X700-30 is discontinued. The direct replacement is the SAIJ80X700-30, which matches the ISO 15552 interface, 80 mm bore, 700 mm stroke, 30 mm adjust window, and G3/8 port.
The external stop screw provides a 30 mm trim window, making the usable extend stroke 670-700 mm. The stop sets position but is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ80X700-30 replacement — usually within 7-8 hours.
