This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X150-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X150-100S in place of this model. 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 Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X150-100S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X150-100S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The exact drop-in replacement is the SAIJ80X150-100S, retaining the 80mm bore, 150mm maximum stroke, G3/8 port, and 25mm piston rod. An external stop screw lets you trim the extend stroke by up to 100mm on-site, giving a usable extend range of 50-150mm. This stop sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or SAIL/BSAI variant for held loads.
At 0.5MPa this bore delivers 2513N push and 2268N pull force, rising to 4523N push at 0.9MPa. The computed safe working load is roughly 1508N (60% of the 0.5MPa push), yielding a 128kg vertical lift with a 2:1 margin. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The ISO 15552 mounting interface lets you reuse existing FA, LB, and TC brackets, and the -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

The SAIJ80X150-100S produces the same force from the same bore — a true drop-in on output. 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).
Pressing or stamping operations where the material thickness varies, using the 100mm adjust screw to set precise extend end positions between 50mm and 150mm without reprogramming the motion controller.
Pneumatic stop gates on packaging lines that require field stroke tuning to handle different carton lengths, using the external stop to shorten the extend stroke on-site.
Lifting assemblies that position parts at varying heights, relying on the 80mm bore's 2513N push force at 0.5MPa and the adjustable end position for precise placement.
To replace the discontinued SIJ80X150-100S, order the drop-in SAIJ80X150-100S, keeping the 80mm bore, 150mm nominal stroke, and 100mm adjust window. When sizing both ways, the neighbouring 63mm bore gives 1559N push at 0.5MPa, while the 100mm bore gives 3927N. Choose the 100mm adjust window if your end-position needs on-site tuning between 50mm and 150mm; the external stop screw sets this end position but does not lock the load. Mounting hardware (FA, LB, TC) reuses the ISO 15552 interface. The -S suffix indicates a built-in magnet for legacy CS1-B/DS1-B switches. For strokes of 300mm or more, verify your side-load limits to prevent excessive guide wear.
Replacement checklist
Yes, the AirTAC SIJ80X150-100S is discontinued. The exact drop-in replacement is the SAIJ80X150-100S. It shares the same ISO 15552 interface, 80mm bore, 150mm stroke, 100mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa. The external stop screw has a 100mm adjust window, allowing you to trim the extend stroke on-site from the 150mm maximum down to 50mm. The stop sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for load holding.
