This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-20 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 MALJ40X225-20
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 205 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-20.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-20
The AirTAC MALJ40X225-20 is a discontinued double-acting mini cylinder with a 20mm rear stroke adjuster. It provides a usable travel window of 205-225mm. The 40mm bore delivers 628N push and 528N pull at 0.5MPa. The direct drop-in replacement is the MBLJ40X225-20.
This SKU lacks a magnet and cannot take a position sensor. The adjuster is a travel stop, not a lock. It uses a fixed rubber bumper, not an adjustable cushion. The old threaded covers are upgraded to a riveted body on the MBLJ.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-20 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-20 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X225-20 |
| Bore size | Ø40 mm |
| Stroke | 225 mm |
| Adjustable window | 205 – 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 MBLJ40X225-20 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 MBLJ40X225-20 matches these values.

Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-20 Is Used
Spindle Deburring Heads
Dial the 205-225mm reach on CNC deburring heads to match varying tool lengths, using the 628N push force to clear burrs.
PCB Test Trays
Fine-tune the end stop for PCB functional test trays without adding external shims, ensuring exact insertion depth.
Carton Flap Folders
Adjust the folding stroke on packaging lines to handle different carton heights, relying on the fixed bumper to soften impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-20 with MBLJ40X225-20
Replace this with the MBLJ40X225-20. Confirm the 40mm bore, 225mm stroke, 20mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). Since this SKU has no -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if needed. The adjuster sets end position but does not hold load without air.
For sizing, step down to the 32mm bore (402N push @0.5MPa) if you have less load, or step up to a larger ISO cylinder if you need more force. This 40mm bore gives 628N push and 880N at 0.7MPa. At 225mm stroke, avoid side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X225-20 (same bore/stroke/adjust)
- ✓ Same 205–225 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 MBLJ40X225-20 instead of this discontinued model.
