This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X160-20, 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 MALJ25X160-20
The AirTAC MALJ25X160-20 is a discontinued double-acting mini cylinder with a 20mm rear adjustable stroke stopper. It provides a usable extension window of 140-160mm. The direct replacement is the MBLJ25X160-20, matching the bore, stroke, force, and G1/8 port.
This SKU lacks a magnet (-S) and cannot accept a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Unlike the older threaded covers on this MALJ, the MBLJ replacement features a riveted rolling-packed body. End impact is softened by a fixed rubber bumper, as there is no adjustable 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 MBLJ25X160-20 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 MBLJ25X160-20 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-20 Is Used
Dispenser Nozzle Height
Fine-tune the 25mm bore cylinder's end position to trim a 20mm window for a fluid dispenser nozzle, ensuring consistent dot volume without reprogramming the PLC.
Small Press Tonnage
Apply up to 50kgf at 1.0MPa for seating small bearings in an assembly press, using the fixed rubber bumper to soften the end impact without requiring an external shock absorber.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-20 with MBLJ25X160-20
To replace the MALJ25X160-20, use the MBLJ25X160-20. Confirm the 25mm bore, 160mm stroke, 20mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Since this SKU lacks the -S magnet, it cannot take a sensor; if you upgrade to an -S MBLJ, note that sensors change from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG family. The rear adjuster is a travel stop, not a lock.
At a 160mm stroke, keep the rod side-load minimized to prevent bending, as the 10mm rod needs straight-line guidance.
Upgrade checklist
- ✓ Order the MBLJ25X160-20 (same bore/stroke/adjust)
- ✓ Same 140–160 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 MBLJ25X160-20 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X160-20 FAQ
Yes, the MALJ25X160-20 is discontinued. The MBLJ upgrades the body to a riveted rolling-packed design from the old threaded covers.
The -20 adjust code lets you trim up to 20mm at the rear, creating a usable 140-160mm window. The adjuster is a travel stop, not a lock, so it will not hold a load without live air pressure.
