This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-75 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 SIJ200X800-75
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-75 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 SAIJ200X800-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-75
The AirTAC SIJ200X800-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. A G3/4 port and 40mm rod equip the 200mm bore. The external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 725-800mm window from the 800mm nominal maximum. It delivers 15708N push and 15080N pull at 0.5MPa, reaching 28274N push at 0.9MPa.
This end-of-life model drops directly into the SAIJ200X800-75, preserving the ISO 15552 mounting interface, adjust window, and force. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 9425N (60% of the 0.5MPa push), translating to an 801kg vertical lift at a 2:1 margin. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAIJ200X800-75 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.

Where the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-75 Is Used
Heavy Press Tonnage Calibration
Needs field stroke tuning to dial in the exact 725-800mm extend endpoint on-site, preventing over-travel when applying up to 28274N of press force at 0.9MPa.
Large Mold Handling
Requires adjusting the extend stop by up to 75mm to accommodate varying mold dimensions while utilizing the 200mm bore's 15708N push at 0.5MPa for heavy extraction.
Oversize Pallet Positioning
Demands on-site stroke trimming to index bulky pallets accurately, leveraging the 50mm adjustable air cushions to decelerate the 40mm rod safely at stroke end.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-75 with the SAIJ200X800-75
To replace the discontinued SIJ200X800-75, order the drop-in SAIJ200X800-75, which matches the 800mm stroke, 75mm adjust window, G3/4 port, and ISO 15552 mounting. When sizing both ways, the neighboring 160mm bore yields 10053N push at 0.5MPa, while this 200mm bore provides 15708N. Choose the 75mm adjust window if your application requires field tuning the extend stroke within 725-800mm; if no trimming is needed, a fixed SAI is simpler. Mounting options include FA, LB, and TC brackets. This SKU lacks the -S magnet and cannot accept a sensor. Because the 800mm stroke exceeds 300mm, ensure external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X800-75
- ✓ 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 SIJ200X800-75 FAQ
Yes, the SIJ200X800-75 is discontinued. The exact drop-in replacement is the SAIJ200X800-75. It shares the identical ISO 15552 interface, 200mm bore, 800mm stroke, 75mm adjust window, G3/4 port, and mounting, but adds an upgraded two Y-shaped one-way piston seal.
The 200mm bore provides 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N at 0.9MPa. The external stop screw window is 75mm, allowing you to trim the extend stroke on-site from the 800mm maximum down to 725mm. The stop sets end position and is not a load lock.
