This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X25-10, 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 MALJ40X25-10
The AirTAC MALJ40X25-10 is a discontinued adjustable-stroke mini cylinder, directly replaced by the direct replacement MBLJ40X25-10. It is a double-acting double-rod unit with a 40mm bore and a 25mm stroke. The rear adjuster allows you to trim up to 10mm, creating a usable end-position window of 15-25mm.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The adjuster functions purely as a travel stop, not a load lock. Upgrading to the MBLJ40X25-10 swaps the old threaded covers for a riveted rolling-packed body while retaining the G1/4 port, M12x1.25 rod thread, and fixed rubber bumper.

| Replacement | MBLJ40X25-10 |
| Bore size | Ø40 mm |
| Stroke | 25 mm |
| Adjustable window | 15 – 25 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |

| 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 MBLJ40X25-10 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 MBLJ40X25-10 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10 Is Used
Connector Crimp Press
Fine-tune the 25mm stroke to crimp wire terminals accurately without changing hard stops, leveraging 528N pull for reliable retraction.
Bottle Capper Head
Adjust the end position to cap various bottle heights on a single line, ensuring consistent torque without over-compressing the caps.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10 with MBLJ40X25-10
To replace the MALJ40X25-10, use the exact direct replacement MBLJ40X25-10. Confirm the 40mm bore, 25mm stroke, 10mm adjust code, PT G1/4 port, and FA/LB mounting (no back cover or SDB). Because this SKU has no -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches. The adjuster sets end position but does not hold load without air.
Upgrade checklist
- ✓ Order the MBLJ40X25-10 (same bore/stroke/adjust)
- ✓ Same 15–25 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 MBLJ40X25-10 instead of this discontinued model.
