This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X30-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X30-10 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 MALJ40X30-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X30-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 20 to 30 mm. This model is discontinued — the drop-in replacement is the MBLJ40X30-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X30-10
The AirTAC MALJ40X30-10 is a discontinued double-acting, single-rod adjustable-stroke mini cylinder. It features a 40mm bore and a 30mm stroke, with a rear screw stopper that allows you to trim the end position by up to 10mm, creating a usable stroke window of 20-30mm. This 40mm bore delivers 628N push and 528N pull force at 0.5MPa. The drop-in replacement is the MBLJ40X30-10, which matches the bore, stroke, force, and G1/4 port.
This SKU lacks the -S magnet option, meaning it cannot accept a position sensor. The MALJ uses a fixed rubber bumper for end-of-stroke impact absorption and has threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body. Remember that the rear adjuster is a travel stop that sets the end position; it does not hold the load without live air pressure.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X30-10 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X30-10 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X30-10 |
| Bore size | Ø40 mm |
| Stroke | 30 mm |
| Adjustable window | 20 – 30 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
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 MBLJ40X30-10 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X30-10 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X30-10 Is Used
PCB Router Z-Axis Stop
Dial in the 20-30mm window on a depaneling router to prevent the Z-axis cutter from crashing into the tooling base, using the 628N force to hold the spindle carriage firmly.
Wire Crimp Height Gauge
Set the exact end-of-stroke position for a terminal crimp press anvil, using the 10mm rear stopper to fine-tune crimp height without physically shimming the machine base.
Pneumatic Press Depth Control
Trim the stroke on a small benchtop assembly press to ensure a bearing is seated to an exact depth rather than bottoming out at full stroke, relying on the fixed rubber bumper to soften the impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X30-10 with MBLJ40X30-10
To replace the MALJ40X30-10, order the MBLJ40X30-10. Confirm the 40mm bore, 30mm stroke, 10mm adjust code, PT G1/4 port, and M12x1.25 rod-end thread. Mounting is limited to FA or LB foot brackets; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot hold a sensor; if you need sensing on the new MBLJ, specify the -S option to switch from the old CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG family. The adjuster is a stop, not a lock.
For sizing, if you need less force, step down to the 32mm bore (402N push @0.5MPa); if you need more thrust, note that 40mm is the largest MALJ bore available, so you would need to migrate to a different cylinder family for higher output.
Upgrade checklist
- ✓ Order the MBLJ40X30-10 (same bore/stroke/adjust)
- ✓ Same 20–30 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 MBLJ40X30-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X30-10 FAQ
Yes, the MALJ40X30-10 is discontinued. The exact drop-in replacement is the MBLJ40X30-10, which matches the 40mm bore, 30mm stroke, 10mm adjust code, and G1/4 port. The MBLJ upgrade uses a riveted rolling-packed body instead of the MALJ's threaded covers, but the force and mounting footprint remain the same.
It delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum force of 128kgf at 1.0MPa. The 30mm stroke can be trimmed by up to 10mm at the rear, giving a usable stroke window of 20-30mm. Note that this SKU has no -S magnet and cannot accept a position sensor.
