This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X65-30-S, 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).
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X65-30-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X65-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 35 to 65 mm. This model is discontinued — the direct replacement is the MBLJ25X65-30-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X65-30-S
The AirTAC MALJ25X65-30-S is a discontinued double-acting double-rod cylinder with a 25mm bore and 65mm stroke. It provides a usable adjustable end-position window of 35-65mm via its 30mm rear stopper. The direct replacement is the MBLJ25X65-30-S.
This -S variant carries a magnet for CS1-M/DS1-M switches, whereas the MBLJ upgrade uses CMSG/DMSG/EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper; the MBLJ uses a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it cannot hold a load without live air pressure.

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 MBLJ25X65-30-S 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 MBLJ25X65-30-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X65-30-S Is Used
Carton Flap Tucking
Adjusts the tucker arm end position on a packaging line to clear varying carton heights, relying on the 206N pull to retract the arm cleanly between cycles.
Textile Loom Tensioning
Fine-tunes the guide bar stroke on a weaving loom to maintain fabric tension without swapping physical spacers, absorbing end impact via the fixed rubber bumper.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X65-30-S with MBLJ25X65-30-S
To replace this MALJ25X65-30-S, install the direct replacement MBLJ25X65-30-S. Confirm the 25mm bore, 65mm stroke, 30mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Note the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster sets end position but is not a lock.
This 25mm bore gives 245N, offering a middle ground for moderate force.
Upgrade checklist
- ✓ Order the MBLJ25X65-30-S (same bore/stroke/adjust)
- ✓ Same 35–65 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 MBLJ25X65-30-S instead of this discontinued model.
