This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X125-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X125-10S 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 SIJ80X125-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 125mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X125-10S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X125-10S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 125 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 115-125 mm end position. The 80 mm bore features a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions, delivering 2513 N push and 2268 N pull at 0.5 MPa. As an end-of-life product, its exact drop-in replacement is the SAIJ80X125-10S, retaining the same interface, bore, stroke, force, and porting.
The SAIJ replacement incorporates an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a computed buyer insight from the 0.5 MPa data suggests a safe working load of roughly 1508 N (60% of push), or a 128 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; the piston drifts on air loss. For held loads, use an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variants the SAI family adds. This -S model includes a piston magnet for legacy CS1-B/DS1-B switches.

The SAIJ80X125-10S 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 operators to dial in the exact insertion depth for bearing press fits without changing the fixture height.
Adjusting the end position by a few millimeters accommodates varying product lengths on a conveyor line, ensuring positive stops without reprogramming the motion controller.
The external stop screw provides a mechanical hard stop for carton folding arms, allowing quick 115-125 mm stroke adjustments to compensate for material thickness variance.
To replace the discontinued SIJ80X125-10S, order the drop-in SAIJ80X125-10S, which preserves the ISO 15552 mounting dimensions, G3/8 port, and 125 mm maximum stroke. The 10 mm adjust window is chosen when you need precise on-site extend tuning between 115-125 mm without mechanical shims. If sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N push. Reuse existing FA, LB, or TC mounts directly. The -S suffix provides a piston magnet for position sensing. For strokes of 300 mm or longer, verify the rod-end side-load limits to prevent guide wear.
Replacement checklist
Yes, the SIJ80X125-10S is discontinued. The exact drop-in replacement is the SAIJ80X125-10S. It shares the identical ISO 15552 interface, 80 mm bore, 125 mm stroke, 10 mm adjust window, G3/8 port, and mounting options, but features an upgraded piston seal for longer life.
The 80 mm bore delivers 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, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 10 mm adjust window, allowing the 125 mm extend stroke to be shortened to 115 mm on-site. This stop sets the end position and is not a load lock.
