This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X180-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X180-75 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 MALJ40X180-75
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X180-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 105 to 180 mm. This model is discontinued — the drop-in replacement is the MBLJ40X180-75.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X180-75
The AirTAC MALJ40X180-75 is a discontinued double-acting mini cylinder with a rear adjustable stroke stopper. Its 75mm adjuster trims the end position, giving a usable reach window of 105-180mm. The 40mm bore delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X180-75.
This SKU has no magnet and cannot accept a position sensor. The adjuster is a travel stop, not a lock, so it will not hold a load without live air. Upgrading to the MBLJ moves you from threaded covers to a riveted rolling-packed body. Both generations use a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X180-75 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X180-75 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X180-75 |
| Bore size | Ø40 mm |
| Stroke | 180 mm |
| Adjustable window | 105 – 180 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
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 MBLJ40X180-75 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X180-75 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X180-75 Is Used
PCB Router Z-Axis Depth
Dial the 105-180mm window to set router depth on a PCB depaneling line, using the 880N push at 0.7MPa to cleanly cut substrate without adding external stops.
Carton Flap Folder
Tune the extended end position on a packaging line folder to match varying box heights, leveraging the 528N pull to snap flaps down securely.
Aluminum Extrusion Press
Fine-tune the rear stopper on a small extrusion press to control material ejection depth, using the 40mm bore's 628N force to push profiles without bottoming out.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X180-75 with MBLJ40X180-75
Replace this MALJ40X180-75 with the MBLJ40X180-75. Confirm the 40mm bore, 180mm stroke, 75mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB allowed). Since this SKU lacks the -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you add one. The adjuster sets end position but does not hold load without air.
Size both ways: step down to a 32mm bore for 402N push at 0.5MPa, or step up if you exceed 128kgf at 1.0MPa. At 180mm stroke, watch rod-to-side-load bending on the 16mm rod.
Upgrade checklist
- ✓ Order the MBLJ40X180-75 (same bore/stroke/adjust)
- ✓ Same 105–180 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 MBLJ40X180-75 instead of this discontinued model.
