This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X800-10S, 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 SIJ80X800-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X800-10S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X800-10S 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 10 mm on-site, giving a usable extend range of 790-800 mm. The nominal 800 mm stroke is the maximum. This 80 mm bore model features a 25 mm piston rod, an M20x1.5 rod-end thread, a G3/8 air port, and 36 mm adjustable air cushions at each end. The direct replacement is the SAIJ80X800-10S, matching the ISO 15552 interface, bore, force, and porting.
The SAIJ replacement upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that the stop screw sets end position only; it is not a load lock.

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 final 10 mm of the extend stroke on-site to set exact pressing depth for bearing insertion without re-mounting the actuator.
Adjusting the extend end position to act as a precise physical stop for parts moving along a conveyor, allowing 790-800 mm reach calibration.
Dialing in the exact extend limit to push pallets squarely against a fixed fence, compensating for slight mechanical drift over time.
To replace the discontinued SIJ80X800-10S, specify the SAIJ80X800-10S directly—it is a direct swap retaining the 800 mm nominal stroke, 10 mm adjust window, G3/8 port, and ISO 15552 mounting. Choose the 10 mm adjust window when you need micro-trim capability for exact end positioning without swapping the cylinder. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). Because the stroke is 800 mm, ensure external guides support side loads to prevent rod bending. The stop screw is not a load lock; for held loads use SAIL, BSAI, or an external rod lock.
Replacement checklist
Yes, the SIJ80X800-10S is discontinued. The direct replacement is the SAIJ80X800-10S. It shares the same ISO 15552 interface, 80 mm bore, 800 mm stroke, 10 mm adjust window, G3/8 port, and mounting options, but features an upgraded two Y-shaped one-way piston seal.
The 10 mm external stop screw window allows a usable extend stroke of 790-800 mm (nominal 800 mm is max). The stop screw sets end position only and does not lock the load.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ80X800-10S replacement — usually within 7-8 hours.
