This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X80-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X80-10S 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 SIJ80X80-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X80-10S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X80-10S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 70-80 mm extend window from the 80 mm nominal maximum. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. It features a Ø25 mm rod, M20x1.5 rod thread, 36 mm adjustable air cushions, a G3/8 port, and a built-in piston magnet (-S) for legacy CS1-B/DS1-B sensors.
With SIJ now end-of-life, the exact drop-in replacement is the SAIJ80X80-10S, reusing the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift with a 2:1 margin. Note the stop screw sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

The SAIJ80X80-10S 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).
Trimming the extend stroke by up to 10 mm on-site allows precise positioning for light press-fit operations without machining custom spacers.
Field-tuning the 70-80 mm extend endpoint lets operators adjust a diverter gate exactly to profile height changes on the line.
The external stop screw provides a hard mechanical end position for consistent carton folding depth, adjustable per format.
To replace the discontinued SIJ80X80-10S, order the drop-in SAIJ80X80-10S, keeping the same 80 mm bore, 80 mm stroke, 10 mm adjust window, G3/8 port, and -S magnet. To size both ways: the neighbouring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N push at 0.7 MPa. Choose the 10 mm adjust window when you need precise 70-80 mm extend endpoint tuning on-site. Mounting is fully ISO 15552 interchangeable (Basic, FA, LB, TC). The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For strokes >=300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SIJ80X80-10S is discontinued. The exact drop-in replacement is the SAIJ80X80-10S, which shares the same ISO 15552 interface, 80 mm bore, 80 mm stroke, 10 mm adjust window, G3/8 port, and mounting. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa (theoretical max 513 kgf at 1.0 MPa). The external stop screw window is 10 mm, allowing you to trim the nominal 80 mm extend stroke down to 70 mm on-site. The stop sets end position and is not a load lock.
