This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-75S 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 SIJ80X100-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X100-75S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X100-75S 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 75 mm on-site, yielding a usable 25-100 mm extension from the 100 mm nominal maximum. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N at 0.9 MPa. It features a 25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, and a fixed G3/8 port. The exact drop-in replacement is the SAIJ80X100-75S.
The SAIJ successor retains the ISO 15552 mounting interface, bore, stroke, adjust window, and force, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, the safe working load is roughly 1508 N (60% of the 0.5 MPa push force), translating to a 128 kg vertical lift with a 2:1 margin. Note the stop screw sets end position only; it is not a load lock, and a plain cylinder drifts on air loss.

The SAIJ80X100-75S 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).
Allows operators to dial in the exact extension distance for pressing bearings or pins where material thickness varies, using the 75 mm trim window to prevent over-travel.
Enables on-site tuning of the diverting arm reach on a packaging line, letting maintenance shorten the extend stroke by up to 75 mm without swapping the cylinder.
Provides a field-adjustable physical end-stop for pallet positioning, accommodating different pallet sizes by trimming the 100 mm nominal stroke down to 25 mm.
To replace the discontinued SIJ80X100-75S, order the drop-in SAIJ80X100-75S, which matches the ISO 15552 interface, 100 mm stroke, 75 mm adjust window, G3/8 port, and 25 mm rod. For force sizing, this 80 mm bore yields 2513 N push at 0.5 MPa; stepping down to a 63 mm bore drops thrust to 1559 N, while stepping up to a 100 mm bore increases it to 3927 N. Choose the 75 mm adjust window if your application requires field tuning of the extend stroke between 25 and 100 mm. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix indicates a built-in piston magnet compatible with legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SIJ80X100-75S is discontinued. The exact drop-in replacement is the SAIJ80X100-75S. It shares the same ISO 15552 interface, 80 mm bore, 100 mm nominal stroke, 75 mm adjust window, G3/8 port, and 25 mm rod, but features an upgraded 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, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extension range of 25-100 mm. The stop sets end position only and is not a load lock.
