This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-40 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 MALJ40X225-40
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 185 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-40.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40
The AirTAC MALJ40X225-40 is a discontinued double-acting, single-rod mini cylinder. It features a 40mm bore, 225mm stroke, and a 40mm rear adjuster that creates a usable end-position window of 185-225mm. It delivers 628N push and 528N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X225-40, matching the bore, stroke, G1/4 port, and force.
This SKU lacks a magnet (-S) and cannot accept 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 fixed rubber bumper softens end impact, but unlike the current-line MBLC, there is no adjustable air cushion. The original MALJ uses threaded covers and older switches, while the MBLJ upgrade features a riveted rolling-packed body.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40 |

| Adjustable window | 185 – 225 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 MBLJ40X225-40 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 MBLJ40X225-40 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40 Is Used
PCB Router Z-Axis
Dial the 185-225mm reach on a PCB depaneling router to set the exact cutting depth without remachining the gantry, using the 628N push to drive the spindle carriage.
Carton Flap Folder
Adjust the 40mm rear stopper on a packaging line case sealer to fine-tune the flap folding height for varying box sizes, relying on the 528N pull to retract the arm.
Pneumatic Press Stop
Set a precise 200mm bottoming position on a small benchtop press for seating bearings, using the 880N force at 0.7 MPa while the rubber bumper absorbs the final impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40 with MBLJ40X225-40
To replace this MALJ40X225-40, order the MBLJ40X225-40. Confirm the 40mm bore, 225mm stroke, 40mm adjust code, G1/4 port, PT threads, and FA/LB mounting (no back cover or SDB). Because this SKU lacks a magnet, no sensor is used; if you later add an -S MBLJ, it uses CMSG/DMSG/EMSG switches instead of the old CS1-M/DS1-M. The adjuster is a stop, not a lock. If sizing down, the 32mm bore offers 402N push at 0.5 MPa; if sizing up, the 40mm is the largest MALJ bore available. At 225mm stroke, use a guide rail to prevent rod bending from side loads.
Upgrade checklist
- ✓ Order the MBLJ40X225-40 (same bore/stroke/adjust)
- ✓ Same 185–225 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 MBLJ40X225-40 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40 FAQ
Yes, the MALJ40X225-40 is discontinued. The exact drop-in replacement is the MBLJ40X225-40, which matches the 40mm bore, 225mm stroke, 40mm adjust code, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The usable adjustable window is 185-225mm (225mm stroke minus the 40mm adjuster). The force figures are 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The rear adjuster is a travel stop, not a lock.
