This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X150-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X150-100 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 SIJ80X150-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X150-100, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X150-100 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 100 mm on-site, giving a usable forward travel of 50-150 mm. The 80 mm bore yields 2513 N push and 2268 N pull at 0.5 MPa via a G3/8 port. The exact drop-in replacement is the SAIJ80X150-100, matching the ISO 15552 interface, force, cushion, and mounting.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is roughly 1508 N (60% of the 2513 N push at 0.5 MPa), translating to a 128 kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. This SKU lacks a magnet (-S), so it cannot accept a magnetic switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X150-100 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ80X150-100 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).
Dials the extend stroke on-site to press parts of different heights without swapping the entire cylinder.
Trims the forward stop position dynamically to accommodate changing package sizes on a packaging line.
Sets precise ejection lengths for varied pallet loads, relying on the 100 mm trim window for exact positioning.
To replace the discontinued SIJ80X150-100, order the drop-in SAIJ80X150-100. Size both ways: the 63 mm neighbor gives 1559 N push at 0.5 MPa, while the 100 mm bore gives 3927 N. Choose the 100 mm adjust window if you need to vary the extend stroke down to 50 mm. Mounting interfaces (FA, LB, TC) reuse existing ISO 15552 holes. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. The stop screw sets end position; it does not hold loads on air loss.
Replacement checklist
Yes, the SIJ80X150-100 is discontinued. The exact drop-in replacement is the SAIJ80X150-100, which matches the ISO 15552 interface, 80 mm bore, 150 mm stroke, 100 mm adjust window, and G3/8 port.
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. The external stop screw allows trimming the extend stroke by up to 100 mm on-site (usable 50-150 mm). The stop sets end position but is not a load lock.
