This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-40S 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 SIJ200X800-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X800-40S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ200X800-40S 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 40 mm on-site, giving a usable 760-800 mm window from the 800 mm nominal maximum. This 200 mm bore delivers 15708 N push and 15080 N pull at 0.5 MPa via its G3/4 port. The exact drop-in replacement is the SAIJ200X800-40S, matching the interface, force, and mounting.
The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or SAIL/BSAI variant for held loads. 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), yielding an ~801 kg vertical lift with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

The SAIJ200X800-40S 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).
Needs field stroke tuning to set precise 760-800 mm pressing depths on large fabricated parts without changing the cylinder body.
Requires adjusting the extend endpoint on-site to accommodate varying material volumes inside a 200 mm bore compaction chamber.
Demands exact extend stops during heavy-duty panel forming, using the 40 mm window to dial in the final 28274 N @0.9 MPa impact position.
To replace the discontinued SIJ200X800-40S, order the drop-in SAIJ200X800-40S, keeping the 40 mm adjust window, 800 mm nominal stroke, and G3/4 port. Size both ways: the neighboring 160 mm bore yields 10053 N push @0.5 MPa, while the 200 mm bore offers 15708 N. Reuse FA, LB, or TC ISO 15552 mounts. The -S magnet enables position sensing; the SAIJ uses current AirTAC switches. For the 800 mm long stroke, use external guides to prevent rod bending and side-load damage. The stop screw trims extend position but does not lock the load.
Replacement checklist
Yes, the SIJ200X800-40S is discontinued. The exact drop-in replacement is the SAIJ200X800-40S. It shares the same ISO 15552 interface, 200 mm bore, 800 mm stroke, 40 mm adjust window, G3/4 port, and mounting. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
The 200 mm bore provides 15708 N push and 15080 N pull @0.5 MPa, 21991 N @0.7 MPa, and 28274 N @0.9 MPa. The external stop screw offers a 40 mm adjust window, making the usable extend stroke 760-800 mm. It operates at 30-500 mm/s with a G3/4 port. The stop sets end position only; it is not a load lock.
