This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X75-40, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X75-40
The AirTAC MALJ25X75-40 is a discontinued double-acting, double-rod mini cylinder with a 40mm rear adjustable stroke stopper. This yields a usable end-position window of 35-75mm. The direct replacement is the MBLJ25X75-40, matching the bore, stroke, adjuster, force, and G1/8 port.
This SKU lacks a magnet (-S), so it cannot take a position sensor. The rear adjuster sets travel but is a stop, not a lock; it will not hold a load without live air. It uses a fixed rubber bumper, not an adjustable cushion. Upgrade details: the MALJ has threaded covers, while the MBLJ uses a riveted rolling-packed body.

| Bore size | Ø25 mm |
| Stroke | 75 mm |
| Adjustable window | 35 – 75 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 300 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 MBLJ25X75-40 carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 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 MBLJ25X75-40 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-40 Is Used
PCB Router Depth Stop
Dial the end position within the 35-75mm window to set precise Z-axis plunging depth for a PCB depaneling router without machining new hard stops.
Label Applicator Reach
Fine-tune the extension reach on a packaging line label applicator, adjusting the stroke on the fly to match varying box widths without changing cylinders.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-40 with MBLJ25X75-40
To replace the MALJ25X75-40, order the MBLJ25X75-40. Confirm the 25mm bore, 75mm stroke, 40mm adjust code, G1/8 port, and PT thread form. Mounting is FA or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a CS1-M/DS1-M sensor, and the MBLJ upgrade would shift to CMSG/DMSG/EMSG switches if needed.
The adjuster is a travel stop, not a load lock.
Upgrade checklist
- ✓ Order the MBLJ25X75-40 (same bore/stroke/adjust)
- ✓ Same 35–75 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 MBLJ25X75-40 instead of this discontinued model.
