This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X750-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X750-20S 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.
Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X750-20S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X750-20S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 750mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X750-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X750-20S
The AirTAC SIJ200X750-20S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore and 750mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, giving a usable window of 730-750mm. This stop sets the end position precisely but is not a load lock. The bore features a 40mm rod, M36x2 thread, G3/4 port, and 50mm adjustable cushions. The exact drop-in replacement is the SAIJ200X750-20S, retaining the same interface, force, and mounting.
Force output is substantial: push 15708N and pull 15080N at 0.5MPa, scaling to 21991N at 0.7MPa and 28274N at 0.9MPa (theoretical max 3204kgf at 1.0MPa). For sizing, a safe working load is roughly 9425N (60% of the 0.5MPa push), yielding an 801kg vertical lift capacity with a 2:1 margin. The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Because plain cylinders drift on air loss, use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X750-20S Is Used
Heavy Press Tonnage
Delivers 15708N push @0.5MPa for large forming presses, using the 20mm on-site stroke trim to set the exact contact distance without re-engineering tooling.
Bulk Material Compaction
Ideal for compacting dense materials where the 730-750mm extend window allows operators to adjust final compression volume precisely on the factory floor.
Large Mold Handling
Moves heavy 800kg molds using the 40mm rod and 50mm cushions, relying on the adjustable stop to fine-tune the mold seating position safely.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X750-20S with the SAIJ200X750-20S
To replace the discontinued SIJ200X750-20S, order the SAIJ200X750-20S drop-in; it preserves the 200mm bore, 750mm stroke, 20mm adjust window, G3/4 port, and -S magnet for legacy CS1-B/DS1-B switches. When sizing both ways, the 160mm neighbor offers 10053N push @0.5MPa, while this 200mm bore delivers 15708N. The 20mm adjust window is ideal for fine-tuning the extend endpoint without machining. Mounting options include Basic, FA, LB, and TC. Because the 750mm stroke exceeds 300mm, ensure external guides to prevent rod bending and manage side loads. The stop screw only sets end position; it does not lock the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X750-20S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X750-20S FAQ
Yes, the SIJ200X750-20S is discontinued. The exact drop-in replacement is the SAIJ200X750-20S. It shares the identical ISO 15552 interface, 200mm bore, 750mm stroke, 20mm adjust window, G3/4 port, and mounting options, but adds an upgraded Y-shaped piston seal for longer life.
The double-acting single-rod cylinder delivers 15708N push and 15080N pull @0.5MPa, 21991N push @0.7MPa, and 28274N push @0.9MPa (max 3204kgf @1.0MPa). The external stop screw provides a 20mm adjust window, allowing the 750mm extend stroke to be shortened to 730mm on-site. The stop sets end position and is not a load lock.
