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

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-75S
The AirTAC SIJ200X800-75S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. A G3/4 port, 40mm rod, and 50mm adjustable cushions frame this heavy-duty unit. 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 at 0.9MPa.
As this SIJ is discontinued, the exact drop-in replacement is the SAIJ200X800-75S, retaining the ISO 15552 mounting interface, bore, and force. The SAIJ upgrade features 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), allowing an 801kg vertical lift with a 2:1 margin. Note the stop screw sets end position only; it is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X800-75S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAIJ200X800-75S 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 SIJ200X800-75S Is Used
Heavy Press Tuning
Final position tuning on a 200mm bore press where a 75mm extend trim window accommodates varying material thicknesses without changing the cylinder.
Large Pallet Positioning
Adjusting the extend stop on-site for oversized pallet loads, using the 725-800mm stroke window to dial in exact placement.
Mold Alignment
Fine-tuning the end position of heavy molds during setup, leveraging the 28274N push force at 0.9MPa and adjustable stop screw.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-75S with the SAIJ200X800-75S
To replace the discontinued SIJ200X800-75S, order the drop-in SAIJ200X800-75S, which matches the ISO 15552 interface, G3/4 port, and 75mm adjust window. When sizing both ways, the neighboring 160mm bore yields 10053N push at 0.5MPa, while the 200mm bore provides 15708N at 0.5MPa or 21991N at 0.7MPa. Select the 75mm adjust window if your extend stroke needs on-site tuning between 725-800mm. Mounting options include FA, LB, and TC. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches. Because the stroke is 800mm, ensure external guides support side loads to prevent rod bending. The stop screw is not a lock; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X800-75S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
