This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X75-10, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X75-10
The AirTAC MALJ25X75-10 is a discontinued double-acting double-rod mini cylinder with a 10 mm rear stroke adjuster. It provides a usable extension window of 65-75 mm, letting you dial in the exact reach without external stops. The direct replacement is the MBLJ25X75-10, matching the bore, stroke, adjust code, G1/8 port and mounting.
This SKU has no magnet and cannot take 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 original MALJ uses threaded covers and a fixed rubber bumper, whereas the MBLJ upgrade features a riveted rolling-packed body. End impact is softened by the bumper only, as there is no air cushion.

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 MBLJ25X75-10 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 MBLJ25X75-10 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-10 Is Used
Carton Flap Tucking
Fine-tune the 10 mm stroke trim on a packaging line case erector to tuck minor flaps at high speed, relying on the fixed rubber bumper to absorb the 800 mm/s end impact.
Aluminum Extrusion Notching
Set a precise end position to push a notching fixture into aluminum profile, using the 206 N pull force to retract the tool clear of the part for robotic unloading.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-10 with MBLJ25X75-10
To replace the MALJ25X75-10, specify the MBLJ25X75-10 to keep the 25 mm bore, 75 mm stroke, 10 mm adjust code, G1/8 PT port, M10x1.25 rod thread and FA/LB mounting. This original SKU lacks the -S magnet, so it cannot support a sensor; if you need position detection on the new MBLJ, add the -S suffix to use CMSG or DMSG switches instead of the older CS1-M/DS1-M. The adjuster is a stop, not a lock, so fit an external locking device for held loads.
Upgrade checklist
- ✓ Order the MBLJ25X75-10 (same bore/stroke/adjust)
- ✓ Same 65–75 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 MBLJ25X75-10 instead of this discontinued model.
