This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-20 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 SIJ200X80-20
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20 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 SAIJ200X80-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20
The AirTAC SIJ200X80-20 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 60-80mm stroke. The 200mm bore delivers 15708N push and 15080N pull at 0.5MPa, features a 50mm adjustable cushion, and uses a fixed G3/4 port. The drop-in replacement is the SAIJ200X80-20, matching the interface, force, and mounting.
The SAIJ upgrade incorporates a two Y-shaped one-way piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is ~9425N (60% of the 0.5MPa push), allowing an 801kg vertical lift with a 2:1 margin. This SKU lacks a -S magnet and cannot take a switch. The stop sets end position but is not a load lock; for held loads use SAIL or BSAI variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X80-20 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 SAIJ200X80-20 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 SIJ200X80-20 Is Used
Heavy Press Tonnage
Provides 15708N extend force at 0.5MPa for heavy pressing, with the 20mm stop screw tuning the exact 60-80mm impact depth on-site.
Bulk Material Compaction
Uses the 200mm bore to deliver massive compaction force, trimming the extend stroke to accommodate varying material fill heights.
Large Mold Positioning
Handles large mold placement with a 60-80mm stroke, allowing precise final position adjustment via the external stop without re-plumbing the G3/4 port.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20 with the SAIJ200X80-20
To replace the discontinued SIJ200X80-20, order the drop-in SAIJ200X80-20, keeping the 80mm nominal stroke and 20mm adjust window. When sizing both ways, note the 160mm bore offers 10053N push at 0.5MPa, while the 200mm bore provides 15708N. Reuse FA, LB, or TC ISO 15552 mounts. Because this SKU has no -S magnet, it cannot accept a sensor. For the 80mm stroke, side-load is minimal. Remember the adjust screw sets end position but is not a lock; use an external rod lock for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-20
- ✓ 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 SIJ200X80-20 FAQ
Yes, the SIJ200X80-20 is discontinued. The exact drop-in replacement is the SAIJ200X80-20, offering the same ISO 15552 interface, 200mm bore, 80mm stroke, 20mm adjust window, G3/4 port, and mounting options.
The 200mm bore delivers 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N push at 0.9MPa. The theoretical max is 3204kgf at 1.0MPa. The external stop screw provides a 20mm adjust window, shortening the 80mm extend stroke down to 60mm on-site. It uses a G3/4 port.
