This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X125-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X125-10 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 MALJ40X125-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 115 to 125 mm. This model is discontinued — the drop-in replacement is the MBLJ40X125-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-10
The AirTAC MALJ40X125-10 is a discontinued 40mm bore, double-acting single-rod mini cylinder with a 125mm stroke and a 10mm rear adjustable stroke stopper. This gives a usable end-position window of 115-125mm. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X125-10, matching bore, stroke, force, G1/4 port, and mounting.
This SKU lacks the -S magnet, so it cannot take a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. End impact is softened by a fixed rubber bumper, not an adjustable air cushion. The MALJ uses threaded covers and a carbon-steel rod with a 20um hard chrome plating, whereas the MBLJ upgrade features a riveted rolling-packed body.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-10 Is Used
Injection Mold Drying
Dial in the exact 115-125mm reach to seat an injection mold drying rack, using the 628N push force to hold the frame without overextending the tooling.
Pallet Case Erector
Fine-tune the 125mm end stop on a corrugated case erector arm, ensuring the 40mm bore's 528N pull reliably tucks the cardboard flap without tearing it.
PCB Router Clamping
Set a precise 120mm clamping depth on a PCB depaneling router fixture, using the fixed rubber bumper to absorb the 880N @0.7MPa end-impact without damaging the board.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-10 with MBLJ40X125-10
To replace this MALJ40X125-10, use the MBLJ40X125-10 drop-in. Confirm the 40mm bore, 125mm stroke, 10mm adjust code, PT G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). Since this SKU has no -S magnet, you lose position sensing; the MBLJ upgrade requires CMSG/DMSG/EMSG switches if you add a magnet. The adjuster is a stop, not a lock.
For sizing, if you need less force, step down to the 32mm bore (402N push @0.5MPa). If you need more force, 40mm is the largest MALJ bore available. For strokes over 300mm, watch for rod-bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ40X125-10 (same bore/stroke/adjust)
- ✓ Same 115–125 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 MBLJ40X125-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-10 FAQ
Yes, the MALJ40X125-10 is discontinued. The exact drop-in replacement is the MBLJ40X125-10, which matches the 40mm bore, 125mm stroke, 10mm adjust code, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the MALJ's threaded covers.
This 40mm bore cylinder provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The 10mm rear adjuster creates a usable stroke window of 115-125mm. The adjuster is a travel stop, not a lock, and this no-S SKU cannot take a position sensor.
