This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-50 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 MALJ40X150-50

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50
The AirTAC MALJ40X150-50 is a discontinued double-acting single-rod cylinder with a 40mm bore and 150mm stroke. A rear screw lets you trim up to 50mm, creating a usable end-position window of 100-150mm. It delivers 628N push and 528N pull at 0.5MPa. The direct drop-in replacement is the MBLJ40X150-50, matching the G1/4 port, M12x1.25 rod thread and force ratings.
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 the end position but will not hold a load without live air. The MALJ uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50 Is Used
PCB router depth stop
Dials the 100-150mm window to set exact Z-axis plunge depth on a CNC router, using the 628N push force to hold the spindle carriage.
Aluminum extrusion press
Fine-tunes the 150mm end position to square up extrusion stock against a hard stop before the hydraulic press cycles.
Pallet wrap film clamp
Adjusts the 50mm trim to grip varying pallet widths securely, relying on the 528N pull force to retract the film carriage.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50 with MBLJ40X150-50
To replace this MALJ40X150-50, order the MBLJ40X150-50. Confirm the 40mm bore, 150mm stroke, 50mm adjust code, G1/4 port, PT thread and FA/LB mounting (no back cover or SDB). Note the adjuster is a stop, not a lock. If sizing down, the 32mm bore offers 402N push at 0.5MPa; if sizing up, 40mm is the largest MALJ bore available.
Because this SKU lacks the -S magnet, it cannot support a sensor. The older MALJ -S used CS1-M/DS1-M switches, while the MBLJ uses CMSG/DMSG/EMSG. At 150mm stroke, watch for rod-bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ40X150-50 (same bore/stroke/adjust)
- ✓ Same 100–150 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 MBLJ40X150-50 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50 FAQ
Yes, the MALJ40X150-50 is discontinued. The exact drop-in replacement is the MBLJ40X150-50, which matches the 40mm bore, 150mm stroke, 50mm adjust code, G1/4 port and mounting. The MBLJ upgrades the threaded covers to a riveted rolling-packed body.
It delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The 50mm adjuster creates a usable stroke window of 100-150mm. The adjuster is a travel stop, not a lock, and this no-S SKU cannot take a sensor.
