This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X160-40, 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 MALJ25X160-40
The AirTAC MALJ25X160-40 is a discontinued double-acting mini cylinder with a 40 mm rear travel stop, creating a usable stroke window of 120-160 mm. The direct replacement is the MBLJ25X160-40, matching the bore, stroke, adjust code, and G1/8 port.
This SKU has no -S magnet and cannot accept a position sensor. The MALJ uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock; it sets the end position but will not 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 MBLJ25X160-40 carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

| 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 MBLJ25X160-40 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-40 Is Used
Aluminum Extrusion End-Facing
Fine-tune the cutting stroke on an extrusion saw to face-cut profiles, relying on the rear stop to prevent the blade from striking the fixture.
Carton Flap Folding Arm
Adjust the reach of a packaging folder arm to accommodate varying box heights, using the stop to halt travel before crushing the cardboard.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-40 with MBLJ25X160-40
To replace this MALJ25X160-40, order the MBLJ25X160-40. Confirm the 25 mm bore, 160 mm stroke, 40 mm adjust code, PT G1/8 port, and M10x1.25 rod thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot support a sensor; if you need sensing on the new unit, specify an MBLJ-S and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
At 160 mm stroke, minimize side loads to prevent rod bending, as the fixed rubber bumper cannot absorb lateral forces.
Upgrade checklist
- ✓ Order the MBLJ25X160-40 (same bore/stroke/adjust)
- ✓ Same 120–160 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 MBLJ25X160-40 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-40 FAQ
Yes, the MALJ25X160-40 is discontinued. The direct replacement is the MBLJ25X160-40, which matches the 25 mm bore, 160 mm stroke, 40 mm adjust code, and G1/8 port. The MBLJ upgrades the construction with a riveted rolling-packed body instead of threaded covers.
The 40 mm adjuster is a travel stop, not a lock, allowing you to trim the end position to create a 120-160 mm usable window. This SKU lacks a magnet, so it cannot take a position sensor.
