This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-50 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 SIJ200 Double Rod Adjustable Cylinder SIJ200X80-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X80-50, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ200X80-50 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. It uses an external stop screw to trim the extend stroke by up to 50 mm on-site, giving a usable 30-80 mm extend window from the 80 mm nominal maximum. The 200 mm bore yields 15708 N push and 15080 N pull at 0.5 MPa, peaking at 28274 N push at 0.9 MPa. It features a 40 mm rod, M36x2 thread, 50 mm adjustable cushions, G3/4 port, and 30-500 mm/s speed.
The exact drop-in replacement is the SAIJ200X80-50, matching the ISO 15552 interface, bore, force, and mountings. 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 ~9425 N (60% of the 0.5 MPa push), allowing a ~801 kg vertical lift with a 2:1 margin. This SKU has no -S magnet, so it cannot take a switch. The stop sets end position, not a lock; for held loads use SAIL or BSAI.

The SAIJ200X80-50 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).
Delivers 28274 N push at 0.9 MPa for high-force pressing, with the 50 mm stop screw tuning the exact 30-80 mm extend position on-site.
Breaks heavy 200 mm bore molds using 15080 N pull at 0.5 MPa, allowing operators to field-trim the extend stroke without swapping cylinders.
Provides up to 15708 N push to clear severe line jams, using the external stop to safely limit the extend stroke and prevent equipment damage.
To replace the discontinued SIJ200X80-50, order the drop-in SAIJ200X80-50, keeping the identical ISO 15552 mounting interface (Basic, FA, LB, TC) and G3/4 port. To size both ways: the neighbouring 160 mm bore gives 10053 N push at 0.5 MPa, while the 200 mm bore provides 15708 N push. Choose the 50 mm adjust window if you need to trim the extend stroke on-site from the 80 mm maximum down to 30 mm. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; add external sensing if required. For strokes >=300 mm, verify the side-load tolerance to prevent rod binding. Remember the external stop is not a load lock; if air is lost, the piston drifts. For held loads, specify an external rod lock or the SAIL/BSAI variant.
Replacement checklist
Yes, the SIJ200X80-50 is discontinued. The exact drop-in replacement is the SAIJ200X80-50. It matches the ISO 15552 interface, 200 mm bore, 80 mm stroke, 50 mm adjust window, 15708 N push force, and G3/4 port. The SAIJ features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The 200 mm bore single-rod cylinder provides 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa (theoretical max 3204 kgf at 1.0 MPa). The external stop screw provides a 50 mm adjust window, allowing you to trim the extend stroke on-site from the 80 mm maximum down to 30 mm. The stop sets end position only; it is not a load lock.
