This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-50 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 SIJ200X800-50 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 SAIJ200X800-50, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ200X800-50 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore and 800mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 50mm on-site, yielding a usable 750-800mm window. This bore delivers 15708N push and 15080N pull at 0.5 MPa, features a 50mm adjustable air cushion at each end, and uses a fixed G3/4 port with an M36x2 rod thread. The exact drop-in replacement is the SAIJ200X800-50, matching the interface, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting footprint for direct reuse of FA, LB, and TC brackets, and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Because this SKU lacks a -S magnet, it cannot accept a magnetic switch. Computed buyer insight: the safe working load is roughly 9425N (about 60% of the 15708N push at 0.5 MPa), translating to a vertical lift capacity of approximately 801kg with a 2:1 margin. The stop screw sets end position only; it is not a load lock.

The SAIJ200X800-50 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).
Needs field stroke tuning to dial in the exact 750-800mm extend position for feeding large blanks into a press, compensating for material thickness variations without re-mounting the cylinder.
Requires on-site stroke trimming to align a 200mm bore pusher precisely against varying pallet widths on a heavy-duty conveyor, using the 50mm stop screw to prevent over-travel.
Demands adjustable end-positioning to clamp oversized aerospace or automotive fixtures securely, allowing operators to fine-tune the 800mm extend stroke to the exact fixture geometry.
To replace the discontinued SIJ200X800-50, order the drop-in SAIJ200X800-50, keeping the same 200mm bore, 800mm nominal stroke, 50mm adjust window, G3/4 port, and ISO 15552 mounting. For sizing both ways, the neighbouring 160mm bore yields 10053N push at 0.5 MPa, while the 200mm bore provides 15708N at 0.5 MPa and 21991N at 0.7 MPa. Choose the 50mm adjust window when you need precise on-site end-position tuning between 750mm and 800mm. Select FA, LB, or TC mountings based on your existing frame. As this SKU has no -S suffix, it cannot support legacy CS1-B or DS1-B sensors. Because the 800mm stroke exceeds 300mm, verify side-load limits and add external guides to prevent rod bending.
Replacement checklist
Yes, the SIJ200X800-50 is discontinued. The exact drop-in replacement is the SAIJ200X800-50, offering the same ISO 15552 interface, 200mm bore, 800mm stroke, 50mm adjust window, G3/4 port, and mounting compatibility.
The double-acting single-rod cylinder delivers 15708N push and 15080N pull at 0.5 MPa, 21991N push at 0.7 MPa, 28274N push at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. The external stop screw provides a 50mm trim window, making the usable extend stroke 750-800mm. The stop sets end position only; it is not a load lock.
