This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X60-30, 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 MALJ20 Adjustable Mini Cylinder MALJ20X60-30
The AirTAC MALJ20X60-30 is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It gives a usable end-position window of 30-60 mm by trimming up to 30 mm at the rear. The direct replacement is the MBLJ20X60-30, matching the bore, stroke, adjust code, G1/8 port, and force.
This SKU has no magnet (-S), so it cannot take a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact. Upgrading to the MBLJ20X60-30 moves from threaded covers to a riveted rolling-packed body, and if a sensor is later needed, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M family.

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 MBLJ20X60-30 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 MBLJ20X60-30 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-30 Is Used
Connector Insertion
Set a 50 mm stroke window to push rectangular connectors into housings, relying on the fixed rubber bumper to absorb the 132 N pull load at the retract position.
Lever Actuation
Fine-tune the reach to trip a micro-lever on a packaging machine by trimming up to 30 mm at the rear, avoiding the need to machine new external hard stops.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-30 with MBLJ20X60-30
To replace the MALJ20X60-30, order the exact direct replacement MBLJ20X60-30. Confirm the 20 mm bore, 60 mm stroke, -30 adjust code, PT G1/8 port, M8x1.25 rod thread, and FA/LB mounting (there is no back cover or SDB option). Remember the adjuster is a stop, not a lock; add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ20X60-30 (same bore/stroke/adjust)
- ✓ Same 30–60 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 MBLJ20X60-30 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-30 FAQ
Yes, the MALJ20X60-30 is discontinued. The direct replacement is the MBLJ20X60-30, which matches the 20 mm bore, 60 mm stroke, 30 mm adjust code, G1/8 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
This specific SKU lacks the -S magnet, so it cannot accept a position sensor; the MBLJ replacement uses CMSG/DMSG/EMSG switches if sensing is later required.
