This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X350-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X350-10 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 MALJ40X350-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X350-10 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 340 to 350 mm. This model is discontinued — the drop-in replacement is the MBLJ40X350-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X350-10
The AirTAC MALJ40X350-10 is a discontinued double-acting mini cylinder with a 40mm bore and 350mm stroke. The -10 adjust code lets you trim the rear end position by up to 10mm, creating a usable 340-350mm window. It delivers 628N push and 528N pull force at 0.5MPa via a G1/4 port. The exact drop-in replacement is the MBLJ40X350-10, matching the bore, stroke, force, and mounting.
This SKU lacks the -S magnet, so it cannot take 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. On long 350mm strokes, side-load alignment is critical to avoid rod bending.

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 MBLJ40X350-10 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X350-10 Is Used
Printed Circuit Board Tester
Dial the 340-350mm reach to probe PCB test fixtures precisely. The 628N push force drives the probe block firmly into contact pads without crushing the board.
Aluminum Extrusion Saw Stop
Set a repeatable 10mm trim on the 350mm cut depth for custom extrusion lengths. The fixed rubber bumper absorbs the saw carriage end impact.
Carton Flap Folder
Fine-tune the folding arm end position on packaging lines. The G1/4 port handles the air volume needed to cycle the 40mm bore rapidly.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X350-10 with MBLJ40X350-10
To replace this MALJ40X350-10, order the MBLJ40X350-10. Confirm the 40mm bore, 350mm stroke, -10 adjust code, G1/4 PT port, and M12x1.25 rod thread. Mounting is Basic, FA, or LB only; there is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a sensor; if you need position detection, the MBLJ replacement requires CMSG, DMSG, or EMSG switches. Remember the adjuster is a stop, not a lock.
For sizing, step down to the 32mm bore (402N push at 0.5MPa) if you need less force, or step up to the 40mm bore's maximum 500mm stroke if you need longer travel. At 350mm, minimize side load to protect the 16mm rod from bending.
Upgrade checklist
- ✓ Order the MBLJ40X350-10 (same bore/stroke/adjust)
- ✓ Same 340–350 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 MBLJ40X350-10 instead of this discontinued model.
