This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X60-40, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40
The AirTAC MALJ40X60-40 is a discontinued adjustable-stroke, double-acting double-rod mini cylinder. Its rear stopper trims up to 40 mm of travel, giving a usable end-position window of 20-60 mm for precise depth control.
The direct replacement is the MBLJ40X60-40, matching the bore, stroke, G1/4 port, and force. This original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrades to a riveted rolling-packed body. Because this SKU lacks the -S magnet, it cannot accept a position sensor.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X60-40 |
| Bore size | Ø40 mm |
| Stroke | 60 mm |
| Adjustable window | 20 – 60 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 MBLJ40X60-40 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ40X60-40 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40 Is Used
PCB edge-guide timing
Adjust the rear stop to sync the rod extension with conveyor flow, leveraging the G1/4 port for rapid cycling.
Pallet stopper arms
Fine-tune the stopping depth for varying pallet heights without adding external spacers to the 40 mm bore body.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-40 with MBLJ40X60-40
To replace the MALJ40X60-40, order the direct replacement MBLJ40X60-40, confirming the 40 mm bore, 60 mm stroke, 40 mm adjust code, PT G1/4 port, and M12x1.25 rod thread. Mounting is Basic, FA, or LB only (no back cover or SDB). Since this SKU has no -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if needed.
Remember the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. An external lock is required for holding.
Upgrade checklist
- ✓ Order the MBLJ40X60-40 (same bore/stroke/adjust)
- ✓ Same 20–60 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 MBLJ40X60-40 instead of this discontinued model.
