This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X200-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X200-50 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 SIJ80X200-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X200-50, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X200-50 is a discontinued double-acting single-rod adjustable-stroke ISO 15552 cylinder. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 150-200 mm window from the 200 mm nominal maximum. At 0.5 MPa this 80 mm bore delivers 2513 N push and 2268 N pull force via its G3/8 port. The drop-in replacement is the SAIJ80X200-50, matching the interface, stroke, force, 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 0.5 MPa push), yielding 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 for held loads. This SKU lacks a -S magnet and cannot take a switch.

The SAIJ80X200-50 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).
Dial in the exact 150-200 mm extend position on-site to accommodate different material thicknesses without swapping the entire actuator.
Tune the extend stop by up to 50 mm to cleanly route varying package sizes onto secondary conveyor lines without reprogramming.
Field-adjust the end position to handle mixed pallet heights, using the 2513 N push force to halt loads reliably.
To replace the SIJ80X200-50, order the drop-in SAIJ80X200-50 (insert A after S), reusing your FA, LB, or TC ISO 15552 mounts. Size both ways: the 63 mm neighbor offers 1559 N push at 0.5 MPa, while the 100 mm bore gives 3927 N. The -50 adjust window provides a 150-200 mm extend range; choose a smaller window if you need finer end-position resolution. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; add external sensing if required. For strokes of 300 mm or longer, verify side-load guide capacity to prevent rod bearing wear.
Replacement checklist
Yes, the SIJ80X200-50 is discontinued. The exact drop-in replacement is the SAIJ80X200-50, offering the same ISO 15552 interface, 80 mm bore, 200 mm stroke, 50 mm adjust window, and G3/8 port. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
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, with a 513 kgf max at 1.0 MPa. The external stop screw window is 50 mm, allowing the extend stroke to be shortened from 200 mm down to 150 mm on-site. The stop sets end position only; it is not a load lock.
