This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X60-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X60-30 in place of this model. 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
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-30 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 30 to 60 mm. This model is discontinued — the drop-in replacement is the MBLJ40X60-30.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-30
The AirTAC MALJ40X60-30 is a discontinued 40mm bore, double-acting single-rod mini cylinder with a 60mm stroke and a 30mm rear adjustable stop. It gives a usable end-position window of 30-60mm. The bore delivers 628N push and 528N pull at 0.5MPa. The exact drop-in 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 |
|---|---|---|

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-30 Is Used
PCB Router Z-Axis
Dials the plunge depth on a PCB depaneling router. The 628N push at 0.5MPa drives the cutting bit, while the 30-60mm window sets exact depth without swapping the cylinder.
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 drop-in 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.
To size both ways: stepping down, the 32mm bore gives 402N push at 0.5MPa; stepping up is not possible as 40mm is the largest MALJ bore. 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.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-30 FAQ
Yes, the MALJ40X60-30 is discontinued. The exact drop-in replacement is the MBLJ40X60-30, which matches the 40mm bore, 60mm stroke, 30mm adjust code, G1/4 port and FA/LB mounting. The MBLJ upgrades the construction from threaded covers to a riveted rolling-packed body.
The bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The 30mm adjust code trims the 60mm stroke, giving a usable end-position window of 30-60mm. The rear adjuster is a travel stop, not a lock; it will not hold a load without live air.
