This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X225-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X225-100 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 SIJ80X225-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X225-100, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X225-100 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The exact drop-in replacement is the SAIJ80X225-100, matching the 80mm bore, 225mm nominal stroke, G3/8 port, and 100mm adjust window. An external stop screw lets you trim the extend stroke on-site by up to 100mm, giving a usable extension range of 125-225mm. The stop sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.
This 80mm bore generates 2513N push and 2268N pull at 0.5MPa, reaching 4523N at 0.9MPa. A 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 SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure. With no -S suffix, this SKU lacks a magnet and cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X225-100 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ80X225-100 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).
Multi-product lines needing different pressing depths use the 100mm adjust window to set exact extend endpoints from 125 to 225mm without changing the cylinder body.
Sortation diverters handling mixed package sizes trim the extend stroke on-site to match varying lane widths, preventing over-travel damage.
End-of-line pallet stops adjust the protrusion distance on-site to accommodate varying pallet heights or partial stack heights safely.
To replace the discontinued SIJ80X225-100, order the drop-in SAIJ80X225-100, reusing your existing ISO 15552 FA, LB, or TC mounts. Sizing both ways: the neighboring 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore yields 3927N. Choose the 100mm adjust window if your fixture tuning requires trimming the full 225mm extension down to 125mm. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; add external proximity switches if position detection is needed. For strokes at or above 300mm, verify side-load limits to prevent guide wear. Remember the stop screw sets end position only; it is not a lock, and the cylinder will drift on air loss.
Replacement checklist
Yes, the SIJ80X225-100 is discontinued. The exact drop-in replacement is the SAIJ80X225-100. It shares the same ISO 15552 interface, 80mm bore, 225mm stroke, 100mm adjust window, G3/8 port, and mounting dimensions. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N at 0.7MPa, and 4523N at 0.9MPa (theoretical max 513 kgf at 1.0MPa). The external stop screw provides a 100mm adjust window, allowing you to shorten the 225mm nominal extend stroke down to 125mm on-site. The stop sets end position but is not a load lock; the cylinder drifts on air loss.
