This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X60-30, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-30

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-30
The AirTAC MALJ40X60-30 is a discontinued 40mm bore, double-acting double-rod mini cylinder with a 60mm stroke and a 30mm rear adjustable stop. It gives a usable end-position window of 30-60mm. The direct replacement is the MBLJ40X60-30, matching the bore, stroke, G1/4 port and mounting.
This SKU has no magnet (-S), so it cannot take a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses threaded covers and fixed rubber bumpers, while the MBLJ upgrade features a riveted rolling-packed body. The adjuster lets you fine-tune the reach depth without external stops.

The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ40X60-30 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ40X60-30 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-30 Is Used
PCB Router Z-Axis
Dials the plunge depth on a PCB depaneling router.
Sheet Metal Press Stop
Acts as an adjustable back-stop for a small sheet-metal press. The 40mm bore handles the 528N pull on retract, and the rear screw lets you trim the 60mm stroke for different blank widths.
Carton Flap Folder
Tunes the folding arm reach on a packaging line. The fixed rubber bumper softens the end impact, and the 30mm adjust range adapts to varying box sizes without adding external stops.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-30 with MBLJ40X60-30
To replace the MALJ40X60-30, order the exact direct replacement MBLJ40X60-30. Confirm the 40mm bore, 60mm stroke, 30mm adjust code, G1/4 port, PT thread, and FA/LB mounting (there is no back cover or SDB option). Because this SKU lacks the -S magnet, it cannot accept a sensor; the MBLJ upgrade switches from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family if you need position detection. Remember the rear adjuster is a stop, not a lock; use an external lock for held loads.
The 60mm stroke is well within the 500mm maximum, avoiding rod-bending side-load risks.
Upgrade checklist
- ✓ Order the MBLJ40X60-30 (same bore/stroke/adjust)
- ✓ Same 30–60 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ40X60-30 instead of this discontinued model.
