This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X225-100, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct replacement is the MBLJ40X225-100.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100
The AirTAC MALJ40X225-100 adjustable-stroke mini cylinder is discontinued. This SKU has no magnet (-S) and cannot take a position sensor.
This double-acting double-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.

| 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 | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ40X225-100 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100 Is Used
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.
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 direct 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 adjuster is a travel stop, not a lock, and this no-S SKU cannot take a position sensor.
