This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X350-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X350-100 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 SIJ80X350-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 350mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X350-100, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X350-100 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80mm bore and 350mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 100mm on-site, yielding a usable 250-350mm window. It delivers 2513N push and 2268N pull at 0.5MPa, uses a G3/8 port, and features a Ø25mm rod with M20x1.5 thread. The exact drop-in replacement is the SAIJ80X350-100, matching the interface, force, and mounting.
The SAIJ upgrade utilizes an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Computed buyer insight: safe working load is roughly 1508N (60% of the 0.5MPa push), allowing a 128kg vertical lift with a 2:1 margin. Note this non-magnetic SKU cannot take a switch. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X350-100 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).
Adjusting the extend stop on-site to tune drill depth precisely across multiple material thicknesses without swapping cylinders.
Trimming the extend stroke by up to 100mm to accommodate changing package widths on a packaging line dynamically.
Setting custom end positions for different pallet heights where the full 350mm stroke is occasionally restricted by 100mm.
To replace the discontinued SIJ80X350-100, order the drop-in SAIJ80X350-100, reusing your FA, LB, or TC ISO 15552 mounts. When sizing both ways, the neighboring 63mm bore yields 2182N push at 0.7MPa, while the 100mm bore yields 3927N push at 0.5MPa. Choose the 100mm adjust window if your field tuning needs the full 250-350mm range. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For the 350mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
Yes, the SIJ80X350-100 is discontinued. The exact drop-in replacement is the SAIJ80X350-100, which shares the identical ISO 15552 interface, 350mm stroke, 100mm adjust window, G3/8 port, and mounting.
It delivers 2513N push / 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa. The external stop screw provides a 100mm adjust window (usable extend 250-350mm). The stop sets end position only and is not a load lock.
