This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X125-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X125-100 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 MALJ40X125-100
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 25 to 125 mm. This model is discontinued — the drop-in replacement is the MBLJ40X125-100.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100
The AirTAC MALJ40X125-100 is a discontinued double-acting single-rod cylinder with a rear adjustable stroke stopper. It has a 40mm bore, 125mm stroke, and a 100mm adjust code, creating a usable extension window of 25-125mm. This bore delivers 628N push and 528N pull force at 0.5 MPa. The exact drop-in replacement is the MBLJ40X125-100, matching the bore, stroke, adjust code, and G1/4 port.
This SKU lacks the -S magnet option, so it cannot accept a position sensor. The original MALJ uses threaded covers and a fixed rubber bumper, whereas the MBLJ upgrade features a riveted rolling-packed body. The rear adjuster is a travel stop that sets the end position; it does not hold the load without live air pressure.

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X125-100 |
| Bore size | Ø40 mm |
| Stroke | 125 mm |
| Adjustable window | 25 – 125 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 |

| 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 MBLJ40X125-100 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X125-100 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100 Is Used
Press Fit Tooling
Dial in the 25-125mm reach on a bearing press fixture. The 628N push force at 0.5 MPa seats caps precisely without over-traveling.
PCB Router Depth Stop
Set a specific end position for a routing spindle. The 100mm rear adjuster lets operators trim depth on the fly without machining new spacers.
Carton Flap Folding
Tune the flap fold arm stroke for varying box heights. The fixed rubber bumper absorbs the 880N impact force at 0.7 MPa at the end of travel.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100 with MBLJ40X125-100
To replace this MALJ40X125-100, order the MBLJ40X125-100. Confirm the 40mm bore, 125mm stroke, 100mm adjust code, PT G1/4 port, and M12x1.25 rod-end thread. Mounting is Basic, FA, or LB only, as there is no back-cover or SDB option. Since this SKU lacks the -S magnet, it cannot take a sensor; if you need sensing on the MBLJ, specify the -S code and upgrade from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
When sizing, note the 32mm bore provides 402N push at 0.5 MPa, while this 40mm bore gives 628N. If you need more force, the 40mm is the largest available in this series. The 100mm adjuster is a travel stop, not a lock, so add an external locking mechanism for held loads. Strokes under 300mm keep side-load rod-bending risk low.
Upgrade checklist
- ✓ Order the MBLJ40X125-100 (same bore/stroke/adjust)
- ✓ Same 25–125 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 MBLJ40X125-100 instead of this discontinued model.
