This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X30-10-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).

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-10-S
The AirTAC MALJ25X30-10-S is a discontinued double-acting, double-rod mini cylinder with a 25mm bore and a 10mm rear adjustable stroke stopper. This gives a usable end-position window of 20-30mm. The direct replacement is the MBLJ25X30-10-S, matching bore, stroke, port and force.
This SKU includes a magnet (-S) for CS1-M/DS1-M switches; the MBLJ replacement upgrades to CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers, while the MBLJ features a riveted rolling-packed body. The adjuster is a travel stop, not a lock, and end impact is absorbed by a fixed rubber bumper, not an adjustable cushion.

Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

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 MBLJ25X30-10-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-10-S Is Used
Connector Seating Jigs
Fine-tune the 10mm rear stopper to gently seat delicate electronic connectors, preventing over-travel damage on the assembly line.
Small-Part Ejection
Adjust the retract end position to eject small plastic moulded parts from a die at the exact 30mm mark before the press cycles again.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-10-S with MBLJ25X30-10-S
To replace the MALJ25X30-10-S, order the exact direct replacement MBLJ25X30-10-S. Confirm the 25mm bore, 30mm stroke, 10mm adjust code, G1/8 port, PT threads, and FA/LB mounting (no back cover or SDB). The -S magnet means swapping older CS1-M/DS1-M switches for CMSG/DMSG/EMSG sensors on the new riveted body. The rear adjuster sets end position but does not hold load without live air.
Upgrade checklist
- ✓ Order the MBLJ25X30-10-S (same bore/stroke/adjust)
- ✓ Same 20–30 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 MBLJ25X30-10-S instead of this discontinued model.
