This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X100-75, 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 MALJ40X100-75
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 25 to 100 mm. This model is discontinued — the direct replacement is the MBLJ40X100-75.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75
The AirTAC MALJ40X100-75 is a discontinued 40mm bore, double-acting double-rod cylinder. It provides a usable stroke window of 25-100mm by letting you trim up to 75mm at the rear stopper. The direct replacement is the MBLJ40X100-75, matching the bore, stroke, and G1/4 port.
This SKU lacks a magnet and cannot take a position sensor. The rear adjuster sets the end position but is a travel stop, not a lock. It uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body. If you previously used a -S magnet, the MBLJ switches to CMSG/DMSG/EMSG sensors.

| Adjustable window | 25 – 100 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |

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 MBLJ40X100-75 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 MBLJ40X100-75 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 Is Used
PCB Router Z-Axis Stop
Set a hard 25mm minimum reach on a PCB depaneling router to prevent spindle crashes, relying on the fixed rubber bumper to soften end impact.
Pallet Dispenser Gate
Adjust the exact 100mm full extension to time the release of empty pallets in a packaging line without bolting on external physical stops.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75 with MBLJ40X100-75
Replace this MALJ40X100-75 directly with the MBLJ40X100-75, confirming the 40mm bore, 100mm stroke, 75mm adjust code, G1/4 port, and PT thread. Mounting is FA or LB only with no back cover or SDB. This SKU has no magnet, so no sensor is used; the MBLJ upgrade moves from CS1-M/DS1-M to CMSG/DMSG/EMSG if you add an -S. The adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ40X100-75 (same bore/stroke/adjust)
- ✓ Same 25–100 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 MBLJ40X100-75 instead of this discontinued model.
