This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-100 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 MALJ40X225-100
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100 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 125 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-100.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100
The AirTAC MALJ40X225-100 adjustable-stroke mini cylinder is discontinued. The exact drop-in replacement is the MBLJ40X225-100, matching the 40mm bore, 225mm stroke, 100mm adjuster, 628N push force at 0.5MPa, and G1/4 port. This SKU has no magnet (-S) and cannot take a position sensor.
This double-acting single-rod unit trims up to 100mm at the rear, creating a usable stroke window of 125-225mm. It uses a fixed rubber bumper, not an adjustable air cushion. The adjuster sets the end position but is a travel stop, not a lock; it will not hold a load without live air pressure. The original MALJ uses threaded covers and the MBLJ upgrade shifts to a riveted rolling-packed body.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X225-100 |
| Bore size | Ø40 mm |
| Stroke | 225 mm |
| Adjustable window | 125 – 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 |

| 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 MBLJ40X225-100 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |

| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X225-100 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100 Is Used
Printed Circuit Board Tester
Dial the 125-225mm reach to probe varying PCB stack heights without changing fixtures, using the 628N push force to secure test contacts.
Packaging Carton Flap Folder
Fine-tune the folding arm end position on the fly for different carton depths, relying on the fixed rubber bumper to absorb the 880N impact at 0.7MPa.
Automotive Component Insertion
Set precise insertion depth for bearing races into housings, adjusting the stopper rather than machining new hard stops for each part variant.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100 with MBLJ40X225-100
To replace the MALJ40X225-100, order the MBLJ40X225-100. Confirm the 40mm bore, 225mm stroke, 100mm adjust code, G1/4 port, PT threads, and FA/LB mounting (no back cover or SDB). This SKU lacks the -S magnet, so it cannot accept a sensor; if you need sensing, the MBLJ upgrade uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Remember the adjuster is a stop, not a lock.
For sizing, step down to the 32mm bore (402N push at 0.5MPa) if your load is lighter, or step up to a larger ISO cylinder if you need more force. At a 225mm stroke, minimize side-load on the 16mm rod to prevent rod-bending and premature seal wear; use a guide for the load.
Upgrade checklist
- ✓ Order the MBLJ40X225-100 (same bore/stroke/adjust)
- ✓ Same 125–225 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 MBLJ40X225-100 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100 FAQ
Yes, the MALJ40X225-100 is discontinued. The exact drop-in replacement is the MBLJ40X225-100, which matches the 40mm bore, 225mm stroke, 100mm adjuster, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if needed.
The 100mm adjust code lets you trim the 225mm stroke, creating a usable window of 125-225mm. The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a max of 128kgf at 1.0MPa. The adjuster is a travel stop, not a lock, and this no-S SKU cannot take a position sensor.
