This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-75S 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 SIJ200X80-75S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X80-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-75S
The AirTAC SIJ200X80-75S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore and 80mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 5-80mm extend window. It features a G3/4 port, M36x2 rod thread, and 50mm adjustable air cushions. The exact drop-in replacement is the SAIJ200X80-75S, matching the interface, bore, stroke, and force.
At 0.5 MPa it delivers 15708N push and 15080N pull, scaling to 28274N push at 0.9 MPa. A computed buyer insight sets the safe working load around 9425N (60% of the 0.5 MPa push), allowing a vertical lift of roughly 801kg with a 2:1 margin. The SAIJ successor retains these metrics but upgrades to a two Y-shaped one-way piston seal for lower start-up pressure. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X80-75S 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 SAIJ200X80-75S 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 SIJ200X80-75S Is Used
Heavy Press Tonnage Calibration
Dial in exact pressing depth on thick materials by trimming the extend stroke up to 75mm on-site, ensuring precise deformation without re-engineering the fixture.
Oversized Payload Positioning
Adapt end-stop positions for varying large pallet dimensions on the fly, using the 200mm bore's 15708N push force to shift heavy loads securely.
Molding Clamp Closure Tuning
Fine-tune mold closure distances safely during setup, relying on the 50mm adjustable air cushions to decelerate the massive 3204kgf theoretical max force.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-75S with the SAIJ200X80-75S
To replace the discontinued SIJ200X80-75S, specify SAIJ200X80-75S for an exact drop-in match. To size both ways, the neighbouring 160mm bore yields 10053N push at 0.5 MPa, while the 200mm bore offers 15708N. Choose the 75mm adjust window if your application requires trimming the 80mm nominal extend down to a 5mm minimum. Mounting options include FA, LB, and TC brackets. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. For strokes over 300mm, carefully manage side-load forces to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-75S
- ✓ 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 SIJ200X80-75S FAQ
Yes, the SIJ200X80-75S is discontinued. The exact drop-in replacement is the SAIJ200X80-75S, sharing the same ISO 15552 interface, 200mm bore, 80mm stroke, 75mm adjust window, G3/4 port, and mounting options.
The 200mm bore provides 15708N push and 15080N pull at 0.5 MPa, 21991N push at 0.7 MPa, and 28274N push at 0.9 MPa. The external stop screw window is 75mm, allowing you to shorten the 80mm nominal extend stroke down to 5mm. The stop sets end position only and is not a load lock.
