This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X1000-30, 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 SIJ80X1000-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X1000-30, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X1000-30 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ80X1000-30. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable stroke of 970-1000 mm. The SAIJ direct keeps the exact mounting interface, force, and adjust window.
The replacement SAIJ family adds an upgraded two-piece Y-shaped piston seal for low start-up pressure and long life. Note this SKU lacks a magnet (-S) and cannot take a switch. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

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).
Needs field stroke tuning to dial in the exact 970-1000 mm extend endpoint during press setup, preventing over-travel without swapping cylinders.
Requires trimming the extend stroke by up to 30 mm on-site to adjust a diverter arm for changing package sizes on the fly.
Demands a precise physical stop at variable product lengths, using the external screw to set the final resting position securely.
To replace the SIJ80X1000-30, order the direct replacement SAIJ80X1000-30, which preserves the 1000 mm max stroke, 30 mm adjust window, G3/8 port, and ISO 15552 mounting. Choose the 30 mm adjust window if you need on-site extend tuning between 970 and 1000 mm. Mounting options include Basic, FA, LB, and TC. Because this SKU has no -S magnet, it cannot accept a sensor. At 1000 mm stroke, prevent rod bending by using external guides to manage side loads.
Replacement checklist
Yes, the SIJ80X1000-30 is discontinued.
The external stop screw window is 30 mm, allowing you to shorten the 1000 mm extend stroke down to 970 mm on-site. The stop sets end position only and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ80X1000-30 replacement — usually within 7-8 hours.
