This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X175-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X175-75S 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 SIJ80X175-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X175-75S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X175-75S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder. A G3/8 port and 25mm rod deliver 2513N push and 2268N pull at 0.5MPa. The external stop screw lets you trim the extend stroke by up to 75mm on-site, giving a usable 100-175mm range. This SIJ is discontinued; the exact drop-in replacement is the SAIJ80X175-75S, sharing the same interface, force, and mounting.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Because the stop screw sets end position, it is not a load lock; use an external rod lock for held loads. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches. For sizing, the safe working load is roughly 1508N (60% of the 0.5MPa push), yielding a 128kg vertical lift capacity with a 2:1 margin.

The SAIJ80X175-75S 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).
Adjust the extend stroke on-site to set precise pressing depths for bearings without re-engineering the fixture.
Trim the extend stroke by up to 75mm to accommodate changing package sizes on a sorting line.
Fine-tune the jaw closure position for varying pouch thicknesses while maintaining high cycle speeds.
To replace the discontinued SIJ80X175-75S, order the drop-in SAIJ80X175-75S, retaining your FA, LB, or TC ISO 15552 mounts. For force sizing, the 80mm bore yields 2513N push at 0.5MPa; if less force is needed, the 63mm bore offers 1559N, while the 100mm bore provides 3927N. The 75mm adjust window allows precise end-position tuning without machining. The -S magnet supports legacy CS1-B/DS1-B sensors. For strokes over 300mm, verify side-load limits to prevent guide wear.
Replacement checklist
Yes, the SIJ80X175-75S is discontinued. The exact drop-in replacement is the SAIJ80X175-75S. It shares the same ISO 15552 interface, 80mm bore, 175mm stroke, 75mm adjust window, and G3/8 port, but features 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 you to trim the extend stroke by up to 75mm on-site, yielding a usable range of 100-175mm. The stop sets position but is not a load lock.
