This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X80-10, 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).
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X80-10
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X80-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 70 to 80 mm. This model is discontinued — the direct replacement is the MBLJ20X80-10.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X80-10
The AirTAC MALJ20X80-10 is a discontinued double-acting mini cylinder with a 10 mm rear travel stop, giving a usable extension window of 70-80 mm. The direct replacement is the MBLJ20X80-10, matching the 20 mm bore, 80 mm stroke, G1/8 port and 10 mm adjust code.
This SKU has no magnet and cannot accept a position sensor. The rear adjuster is a travel stop, not a lock, so it cannot hold a load without live air. The fixed rubber bumper softens end impact. Upgrading to the MBLJ changes the threaded covers to a riveted rolling-packed body.

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 MBLJ20X80-10 carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | — |
| Max (@1.0 MPa) | 27 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 MBLJ20X80-10 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X80-10 Is Used
Dispenser Nozzle Height
Fine-tunes a 72 mm drop for an adhesive dispensing nozzle on a packaging line, trimming the 10 mm rear stop to prevent the tip from crashing into the carton base.
Light-Part Ejector
Pushes small plastic caps out of a mold cavity at a 78 mm stroke, relying on the fixed rubber bumper to soften the ejection impact without damaging the parts.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X80-10 with MBLJ20X80-10
To replace this MALJ20X80-10, order the MBLJ20X80-10. Confirm the 20 mm bore, 80 mm stroke, 10 mm adjust code, PT G1/8 port, M8x1.25 rod thread and FA/LB mounting. This unit has no -S magnet, so no sensor is needed, but note the MBLJ uses CMSG/DMSG/EMSG switches if you ever add one. The adjuster sets end position but does not lock the load.
If sizing either way, stepping down to a non-adjustable MAL16 drops the 0.5 MPa push force to about 124 N, while stepping up to a MAL25 raises it to 245 N. For any stroke over 300 mm on these mini bodies, watch rod bending from side loads.
Upgrade checklist
- ✓ Order the MBLJ20X80-10 (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 MBLJ20X80-10 instead of this discontinued model.
