This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-40 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 SIJ80X100-40 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 SAIJ80X100-40, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X100-40 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. It features an 80mm bore, a 100mm nominal extend stroke, and an external stop screw that lets you trim the extend stroke by up to 40mm on-site, yielding a usable 60-100mm window. The stop sets the end position but is not a load lock. It delivers 2513N push and 2268N pull at 0.5MPa, with a 4523N push at 0.9MPa. This SKU has no -S magnet and cannot take a sensor.
The exact drop-in replacement is the SAIJ80X100-40, preserving the ISO 15552 mounting interface, 25mm rod, G3/8 port, and force. 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), giving a ~128kg vertical lift with a 2:1 margin. For held loads, use SAIL/BSAI or an external rod lock, as air cushions only decelerate.

The SAIJ80X100-40 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).
Trim the extend stroke by up to 40mm on-site to change drill depth without swapping cylinders.
Tune the 100mm extend stroke to handle varying box widths on a packaging line.
Field-adjust the end position to act as a physical stop for different pallet profiles.
To replace this discontinued SIJ80X100-40, order the drop-in SAIJ80X100-40, keeping the 40mm adjust window (60-100mm usable extend) and G3/8 port. Size both ways: the 63mm bore yields 1559N push @0.5MPa, while the 100mm bore yields 3927N. This 80mm bore provides 2513N push @0.5MPa and 4523N @0.9MPa. Reuse FA, LB, or TC mounts via the ISO 15552 interface. This non-magnetic SKU cannot take a switch; add -S for legacy CS1-B/DS1-B sensing. For stroke >=300mm, verify side-load guidance. Remember: double-acting single-rod only; the stop screw sets position, it does not lock.
Replacement checklist
Yes, the SIJ80X100-40 is discontinued. The exact drop-in replacement is the SAIJ80X100-40. It shares the same ISO 15552 interface, 80mm bore, 100mm stroke, 40mm adjust window, 4523N push @0.9MPa, G3/8 port, and mounting.
The double-acting single-rod 80mm bore delivers 2513N push / 2268N pull @0.5MPa, 3518N @0.7MPa, and 4523N @0.9MPa (513 kgf max). The external stop screw trims the extend stroke by up to 40mm on-site, giving a 60-100mm usable window. The stop sets end position; it is not a lock.
