This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-30S 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 SIJ200X80-30S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-30S 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 SAIJ200X80-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-30S
The AirTAC SIJ200X80-30S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. It features a 200mm bore, an 80mm nominal extend stroke, and a built-in piston magnet (-S) for legacy CS1-B/DS1-B switches. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 50-80mm stroke window. The stop sets the end position but is not a load lock; loads drift on air loss. The exact drop-in replacement is the SAIJ200X80-30S, retaining the G3/4 port, M36x2 rod thread, and 50mm adjustable cushions.
At 0.5MPa this bore delivers 15708N push and 15080N pull force, scaling to 28274N push at 0.9MPa. The SAIJ successor reuses the ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Computed buyer insight: safe working load is roughly 9425N (60% of the 0.5MPa push), and vertical lift capacity is about 801kg with a 2:1 margin. The SAIJ family also introduces SAIL and BSAI lock variants absent in the SI line.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X80-30S 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 SAIJ200X80-30S 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 SIJ200X80-30S Is Used
Heavy Press Tonnage
Apply up to 28274N of push force at 0.9MPa for heavy assembly presses, using the 30mm stop screw to dial in the exact 50-80mm contact distance on-site.
Vertical Load Lowering
Lower masses up to 801kg with a 2:1 safety margin, relying on the external stop to set the exact resting position without needing custom spacer spacers.
Adjustable Height Stops
Trim the extend stroke by up to 30mm on-site to accommodate varying product heights in packaging or forming dies without changing the cylinder.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-30S with the SAIJ200X80-30S
To replace the discontinued SIJ200X80-30S, order the exact drop-in SAIJ200X80-30S, which matches the 200mm bore, 80mm stroke, 30mm adjust window, G3/4 port, and ISO 15552 mounting. If sizing both ways, the neighboring 160mm bore yields 10053N push at 0.5MPa, while the 200mm bore offers 15708N. Choose the 30mm adjust window when you need precise 50-80mm extend tuning on-site. Mounting options include FA, LB, and TC brackets. The -S suffix indicates a piston magnet for CS1-B/DS1-B switches. For strokes at or above 300mm, carefully manage side loads to prevent rod bearing wear. For held loads, use an external rod lock or pilot-operated check valve, as the stop screw is not a brake.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-30S
- ✓ 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 SIJ200X80-30S FAQ
Yes, the AirTAC SIJ200X80-30S is discontinued. The exact drop-in replacement is the SAIJ200X80-30S. It shares the same ISO 15552 interface, 200mm bore, 80mm nominal stroke, 30mm adjust window, G3/4 port, and mounting options, but features an upgraded piston seal.
The 200mm bore provides 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N push at 0.9MPa (max 3204kgf at 1.0MPa). The external stop screw allows trimming the extend stroke by up to 30mm on-site, giving a usable 50-80mm window. The stop sets end position and is not a load lock.
