This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X1000-10, 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 SIJ80X1000-10 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 SAIJ80X1000-10, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X1000-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, discontinued and replaced by the SAIJ80X1000-10. It has an 80mm bore, G3/8 port, and a 1000mm maximum extend stroke. The external stop screw lets you trim the extend stroke by up to 10mm on-site (usable 990-1000mm). The stop sets end position and is not a load lock; use SAIL or BSAI for held loads.
The SAIJ direct adds an upgraded two Y-shaped piston seal for low start-up pressure. This non-magnet SKU cannot take switches.

| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X1000-10 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).
Trimming the 1000mm extend by 10mm on-site synchronizes a long-stroke pusher with conveyor pallets without machining spacers.
Fine-tunes the exact end position for varying pallet widths on a 80mm bore ISO 15552 line, using the stop screw for a 990-1000mm stroke.
To replace the discontinued SIJ80X1000-10, use the direct replacement SAIJ80X1000-10 (same ISO 15552 interface, 80mm bore, 1000mm stroke, 10mm adjust window, G3/8 port, M20x1.5 rod thread, and 36mm cushions). Choose the 10mm adjust window if you need minor 990-1000mm extend tuning; for larger trims, pick a different adjust suffix. Mounting options include FA, LB, and TC. As this is a non-magnet SKU, it cannot take a magnetic switch. Because the 1000mm stroke is long, ensure external guides to prevent rod bending and manage side loads.
Replacement checklist
Yes, the SIJ80X1000-10 is discontinued. The direct replacement is the SAIJ80X1000-10, matching the ISO 15552 interface, 80mm bore, 1000mm stroke, 10mm adjust window, G3/8 port, and force.
It is a double-acting double-rod cylinder with a 25mm rod, G3/8 port, M20x1.5 thread, and 36mm cushions. The 10mm adjust window allows a 990-1000mm extend stroke. The stop sets end position, not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ80X1000-10 replacement — usually within 7-8 hours.
