This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X600-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X600-40 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X600-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40
The AirTAC SIJ80X600-40 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 600 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, giving a usable extend range of 560-600 mm. The stop sets the end position but is not a load lock. This 80 mm bore uses a G3/8 port, a 25 mm rod, and delivers 2513 N push / 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa.
This SIJ model is discontinued; the exact drop-in replacement is the SAIJ80X600-40, sharing the same interface, force, and G3/8 port. The SAIJ upgrade uses a two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet (-S) so it cannot take a switch.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X600-40 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40 Is Used
Variable Pitch Indexing
Dialing the extend stop by up to 40 mm allows a single actuator to push parts into fixtures at varying depths without swapping mechanical hardstops.
Adjustable Transfer Diverter
Tuning the extend end position on-site lets a diverter gate accommodate different package widths on the fly, ensuring accurate routing.
Variable Height Pallet Stops
Trimming the extend stroke by 40 mm provides precise positioning for different pallet heights, preventing over-travel during loading.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40 with the SAIJ80X600-40
To replace the discontinued SIJ80X600-40, order the drop-in SAIJ80X600-40, keeping the 40 mm adjust window (560-600 mm usable extend) and ISO 15552 mounting. When sizing both ways: the 63 mm bore neighbor yields 2182 N push at 0.7 MPa, while the 100 mm bore gives 5497 N push at 0.7 MPa—compared to this 80 mm bore's 3518 N at 0.7 MPa. Reuse FA, LB, or TC mounts. Because this SKU has no -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For the 600 mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; the cushion only decelerates, so for load holding use an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40 FAQ
Yes, the SIJ80X600-40 is discontinued. The exact drop-in replacement is the SAIJ80X600-40. It shares the same ISO 15552 interface, 80 mm bore, 600 mm stroke, 40 mm adjust window, G3/8 port, and mounting options, while adding an upgraded two-piece Y-shaped piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa (max 513 kgf). The external stop screw allows trimming the extend stroke by up to 40 mm on-site (usable range 560-600 mm). It uses a G3/8 port and runs at 30-800 mm/s.
