This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X80-10, 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 MALJ25X80-10
The AirTAC MALJ25X80-10 is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It features a 25mm bore, an 80mm stroke, and a 10mm rear adjuster, giving a usable end-position window of 70-80mm. The direct replacement is the MBLJ25X80-10, which matches the bore, stroke, adjust code, G1/8 port, and mounting.
The rear adjuster is a travel stop, not a lock; it will not hold a load without live air pressure. This SKU lacks a magnet (-S), so it cannot accept a position sensor. During the upgrade to MBLJ25X80-10, the threaded covers change to a riveted rolling-packed body, and the fixed rubber bumper remains standard. There is no back cover or SDB option; mounting is FA or LB only.

| Bore size | Ø25 mm |
| Stroke | 80 mm |
| Adjustable window | 70 – 80 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 MBLJ25X80-10 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 MBLJ25X80-10 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-10 Is Used
Connector Insertion Press
Fine-tune the downward travel when pressing pin headers into plastic housings, preventing connector body damage by stopping the rod precisely at the 70mm adjusted position.
Carton Flap Folder
Adjust the end position to time the folding stroke on varying box heights, using the 206N pull force to retract the folding arm cleanly behind the carton path.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-10 with MBLJ25X80-10
To replace the MALJ25X80-10, order the MBLJ25X80-10. Confirm the 25mm bore, 80mm stroke, 10mm adjust code, G1/8 port, PT thread, and FA/LB mounting. The adjuster is a travel stop, not a lock. This 80mm stroke is well under the 300mm max, so rod-bending side-load risks are low.
Upgrade checklist
- ✓ Order the MBLJ25X80-10 (same bore/stroke/adjust)
- ✓ Same 70–80 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 MBLJ25X80-10 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-10 FAQ
Yes, the MALJ25X80-10 is discontinued. The direct replacement is the MBLJ25X80-10, which matches the 25mm bore, 80mm stroke, 10mm adjuster, G1/8 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design, but the force and fixed rubber bumper remain the same.
The rear adjuster is a travel stop that sets the 70-80mm end-position window, not a lock; it cannot hold a load without live air. Also, this SKU has no magnet, so it cannot accept a CS1-M or DS1-M sensor.
