This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X175-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X175-40 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 MALJ40X175-40
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-40 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 135 to 175 mm. This model is discontinued — the drop-in replacement is the MBLJ40X175-40.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-40
The AirTAC MALJ40X175-40 is a discontinued adjustable-stroke mini cylinder. As a double-acting single-rod unit, it delivers 628 N push and 528 N pull force at 0.5 MPa. The -40 adjuster creates a usable 135-175 mm end-position window. The drop-in replacement is the MBLJ40X175-40, matching this bore, stroke, port, and force exactly.
This SKU lacks a -S magnet and cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it will not hold a load without live air. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. If you need position feedback, the MBLJ uses CMSG, DMSG, or EMSG switches.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-40 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-40 |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-40 Is Used
CNC Vise Clamping
Dial in the 135-175 mm reach to clamp aluminum workpieces in a CNC machining center, using the 628 N push force to secure the part without over-stroking.
PCB Router Depth Stop
Set a precise end position for a pneumatic router head on an electronics assembly line, preventing the rod from crashing into delicate printed circuit boards.
Packaging Flap Folder
Adjust the travel window on a carton erector to fold varying box flap depths accurately, relying on the fixed rubber bumper to absorb the end impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-40 with MBLJ40X175-40
To replace the MALJ40X175-40, order the MBLJ40X175-40. Confirm the 40 mm bore, 175 mm stroke, 40 mm adjust code, G1/4 port, and PT thread. Mounting is FA or LB only; there is no back-cover or SDB option. The adjuster sets end position but does not hold load without air. Since this SKU has no -S magnet, it cannot take a sensor; the MBLJ replacement requires CMSG, DMSG, or EMSG switches.
For sizing, if you need less force, step down to the 32 mm bore (402 N push at 0.5 MPa). If you need more force, step up to a larger standard cylinder. At 175 mm stroke, prevent rod-bending by minimizing side loads on the M12x1.25 rod end.
Upgrade checklist
- ✓ Order the MBLJ40X175-40 (same bore/stroke/adjust)
- ✓ Same 135–175 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 MBLJ40X175-40 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-40 FAQ
