This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-30 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 MALJ40X150-30
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-30 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 120 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-30.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-30
The AirTAC MALJ40X150-30 is a discontinued 40mm bore, double-acting mini cylinder with a 150mm stroke and a 30mm rear adjustable stop. It gives a usable reach window of 120-150mm. The bore delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X150-30, matching the force, G1/4 port, and mounting.
This SKU has no -S magnet, so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it sets end position but will not hold a load without live air. Upgrading to the MBLJ replaces the threaded covers with a riveted rolling-packed body. End impact is softened by a fixed rubber bumper, as there is no air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-30 Technical Specifications

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-30 Is Used
PCB Router Z-Axis Depth Stop
Dial the 120-150mm window to set exact Z-axis plunge depth on a PCB depaneling router, preventing the 628N push force from gouging the tooling base.
Automated Carton Flap Folder
Fine-tune the 150mm stroke end position on a packaging line flap folder, accommodating varying corrugated box heights without adding external spacers.
Plastic Injection Mold Ejector
Trim the rear travel by 30mm to time the ejection stroke on a plastic injection molding machine, protecting the 16mm rod from over-travel impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-30 with MBLJ40X150-30
To replace this MALJ40X150-30, order the drop-in MBLJ40X150-30. Confirm the 40mm bore, 150mm stroke, 30mm adjust code, G1/4 port, PT thread, and FA or LB mounting. There is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot take a sensor; if you need sensing, the MBLJ equivalent requires CMSG/DMSG/EMSG switches. The adjuster is a stop, not a lock; use an external lock for held loads. If sizing down, the 32mm bore yields 402N push at 0.5MPa; if stepping up, there is no larger MALJ bore, so consider a standard ISO cylinder for higher force.
Upgrade checklist
- ✓ Order the MBLJ40X150-30 (same bore/stroke/adjust)
- ✓ Same 120–150 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 MBLJ40X150-30 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-30 FAQ
Yes, the MALJ40X150-30 is discontinued. The exact drop-in replacement is the MBLJ40X150-30, which matches the 40mm bore, 150mm stroke, 30mm adjust code, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The usable stroke window is 120-150mm, set by the 30mm rear adjuster. The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The adjuster is a travel stop, not a lock.
