This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X65-50, 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 MALJ25X65-50
The AirTAC MALJ25X65-50 is a discontinued double-acting mini cylinder with a 50mm rear adjustable stroke stopper. It provides a usable end-position window of 15-65mm. The direct replacement is the MBLJ25X65-50, matching the bore, stroke, G1/8 port, and force ratings.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact. The original MALJ uses threaded covers and the new MBLJ uses a riveted rolling-packed body. If you previously used a -S version, note the MBLJ upgrades the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.

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 MBLJ25X65-50 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 MBLJ25X65-50 matches these values.

Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X65-50 with MBLJ25X65-50
To replace the MALJ25X65-50, order the MBLJ25X65-50. Confirm the 25mm bore, 65mm stroke, 50mm adjust code, G1/8 PT port, and M10x1.25 rod-end thread. Mounting is FA or LB only; there is no back cover or SDB option. Remember the adjuster is a stop, not a lock, so add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ25X65-50 (same bore/stroke/adjust)
- ✓ Same 15–65 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 MBLJ25X65-50 instead of this discontinued model.
