This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-75 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 SIJ80X100-75 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 SAIJ80X100-75, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X100-75 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 75mm on-site, yielding a usable 25-100mm extension from the 100mm nominal maximum. This 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, features a G3/8 port, and includes 36mm adjustable air cushions.
The exact drop-in replacement is the SAIJ80X100-75, matching the interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is ~1508N (60% of the 0.5MPa push), allowing a ~128kg vertical lift with a 2:1 margin. The stop sets end position only; it is not a load lock, and this non-S SKU cannot take a magnetic switch.

The SAIJ80X100-75 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).
Needs field stroke tuning to set precise metal stamping depths on-site without swapping cylinders.
Needs field stroke tuning to alter the extend reach for varying box widths on a sorting line.
Needs field stroke tuning to trim the extend stop position for different pallet load heights.
Replace the SIJ80X100-75 directly with the SAIJ80X100-75. When sizing both ways, the neighboring 63mm bore yields 1559N push, while the 100mm bore yields 3927N push at 0.5MPa. Choose the 75mm adjust window if you need to cut the 100mm nominal extension down to a 25mm minimum on-site. Reuse FA, LB, or TC ISO 15552 mounts. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. For strokes >=300mm, verify side-load limits. Note the stop screw sets end position but is not a lock; for held loads use SAIL/BSAI or an external rod lock.
Replacement checklist
Yes, the SIJ80X100-75 is discontinued. The exact drop-in replacement is the SAIJ80X100-75, matching the ISO 15552 interface, 80mm bore, 100mm stroke, 75mm adjust window, and G3/8 port.
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 window is 75mm, shortening the 100mm nominal extend stroke down to 25mm. The stop sets end position only and is not a load lock.
