This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X275-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X275-10 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 SIJ80X275-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 275mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X275-10, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X275-10 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80mm bore and 275mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 10mm on-site, yielding a usable 265-275mm extension window. It delivers 2513N push and 2268N pull force at 0.5MPa, features a 25mm rod, M20x1.5 thread, and a fixed G3/8 port. The exact drop-in replacement is the SAIJ80X275-10, matching the ISO 15552 interface, force, and mounting.
The SAIJ successor retains the adjustable cushion (36mm at each end) and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, the safe working load is roughly 1508N (60% of the 2513N push at 0.5MPa), translating to a 128kg vertical lift with a 2:1 safety margin. This non-magnet SKU cannot accept a switch. The stop screw sets the end position but is not a lock; cylinders drift on air loss, so use an external rod lock for held loads.

The SAIJ80X275-10 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).
Fine-tune the 265-275mm extend endpoint on-site to set precise pressing depth for bearing insertion without machining custom spacers.
Trim the extend stroke by up to 10mm to alter the physical stop position for varying product widths on a pneumatic routing conveyor.
Dial in the exact 80mm bore extend position to accommodate minor carton height variances, using the 2513N push force to hold flaps securely.
To replace the discontinued SIJ80X275-10, order the drop-in SAIJ80X275-10, which preserves the 275mm nominal stroke, 10mm adjust window, G3/8 port, and 2513N push force at 0.5MPa. When sizing both ways, the neighboring 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore yields 3927N. Choose the 10mm adjust window if you only need minor end-position tuning between 265mm and 275mm; for larger trims, select a model with a wider window. Mounting interfaces (Basic, FA, LB, TC) are fully reusable under ISO 15552. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. For stroke lengths of 300mm or more, verify your side-load limits to prevent excessive rod wear.
Replacement checklist
Yes, the SIJ80X275-10 is discontinued. The exact drop-in replacement is the SAIJ80X275-10. It shares the identical ISO 15552 interface, 80mm bore, 275mm stroke, 10mm adjust window, G3/8 port, and mounting options, while adding an upgraded piston seal.
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 allows trimming the extend stroke by up to 10mm on-site, giving a usable 265-275mm extension. The stop sets end position and is not a load lock.
