This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X50-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X50-10 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 MALJ40X50-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10 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 40 to 50 mm. This model is discontinued — the drop-in replacement is the MBLJ40X50-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10
The AirTAC MALJ40X50-10 is a discontinued 40mm bore, double-acting single-rod mini cylinder with a 10mm rear adjustable stroke stopper. It yields a usable extension window of 40-50mm, delivering 628N push and 528N pull force at 0.5 MPa. The drop-in replacement is the MBLJ40X50-10, matching the bore, stroke, G1/4 port, and mounting.
This SKU lacks the -S magnet and cannot accept a position sensor. The MALJ uses a fixed rubber bumper and threaded covers, whereas the MBLJ replacement features a riveted rolling-packed body. The rear adjuster sets the end position but does not hold load without live air; use an external lock for suspended loads.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X50-10 |
| Bore size | Ø40 mm |
| Stroke | 50 mm |
| Adjustable window | 40 – 50 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 MBLJ40X50-10 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10 Is Used
PCB Router Z-Axis
Dial in the 40-50mm descent on a PCB depaneling router. The 10mm stopper fine-tunes the cutting depth without Machining new spacers, using the 628N push to drive the spindle.
Pneumatic Press Fit
Press bushings into aluminum housings. The fixed rubber bumper absorbs the 880N impact at 0.7 MPa, while the rear stop sets the exact 45mm seating depth to prevent housing distortion.
Packaging Fold Arm
Adjust the carton end-flap fold arm. The 10mm rear stop lets operators shift the 528N pull stroke window for different box heights without changing the physical cylinder mounting block.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10 with MBLJ40X50-10
To replace the MALJ40X50-10, order the MBLJ40X50-10. Confirm the 40mm bore, 50mm stroke, 10mm adjust code, PT G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). If migrating, note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG, though this specific no-S SKU cannot take a sensor. The adjuster is a travel stop, not a lock.
If sizing force, the next size down is the 32mm bore (402N push at 0.5 MPa) and the next size up is the largest in the range, the 40mm bore itself (max 128 kgf at 1.0 MPa). At a 50mm stroke, side-load risk is low, but keep the rod guided.
Upgrade checklist
- ✓ Order the MBLJ40X50-10 (same bore/stroke/adjust)
- ✓ Same 40–50 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 MBLJ40X50-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10 FAQ
Yes, the MALJ40X50-10 is discontinued. The exact drop-in replacement is the MBLJ40X50-10, which matches the 40mm bore, 50mm stroke, 10mm adjust code, G1/4 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design.
The 10mm adjust code creates a usable stroke window of 40-50mm. The full force figures are: 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The adjuster is a travel stop, not a lock.
