This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X150-75, 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 MALJ40X150-75
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75 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 75 to 150 mm. This model is discontinued — the direct replacement is the MBLJ40X150-75.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75
The AirTAC MALJ40X150-75 is a discontinued 40mm bore, double-acting double-rod mini cylinder with a 75mm rear adjuster. The rear screw lets you trim the end position, creating a usable stroke window of 75-150mm without adding external stops. This SKU has no magnet and cannot take a sensor.
The direct replacement is the MBLJ40X150-75, matching the 40mm bore, 150mm stroke, 75mm adjust code, force, and G1/4 port. Upgrading swaps the threaded covers for a riveted rolling-packed body. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air.

| 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 MBLJ40X150-75 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75 Is Used
Aluminum Extrusion Notcher
Adjusts the notch depth for aluminum profiles, relying on the 40mm bore's 528N pull force to cleanly retract the tooling from deep cuts without needing external mechanical stops.
Packaging Carton Flap Folder
Fine-tunes the folding arm reach on a case erector, trimming up to 75mm at the rear to handle varying carton heights while the fixed rubber bumper absorbs the 880N end impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75 with MBLJ40X150-75
Replace the MALJ40X150-75 with the exact MBLJ40X150-75 direct. Confirm the 40mm bore, 150mm stroke, 75mm adjust code, PT G1/4 port, and M12x1.25 rod thread. Mounting is FA or LB only; there is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot hold a sensor; if you need position detection on the new unit, specify an MBLJ-S model to use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster sets end position but does not lock the load.
For a 150mm stroke, use a guide rail to prevent rod bending and side-load wear.
Upgrade checklist
- ✓ Order the MBLJ40X150-75 (same bore/stroke/adjust)
- ✓ Same 75–150 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 MBLJ40X150-75 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75 FAQ
Yes, the MALJ40X150-75 is discontinued. The direct replacement is the MBLJ40X150-75, which matches the 40mm bore, 150mm stroke, 75mm adjust code, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The 75mm adjuster is a travel stop that lets you trim the usable stroke window down to 75-150mm; it does not lock the load without live air. This SKU has no -S magnet and cannot accept a position sensor.
