This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X60-20, 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 MALJ20 Adjustable Mini Cylinder MALJ20X60-20
The AirTAC MALJ20X60-20 is a discontinued double-acting double-rod mini cylinder with a 20 mm bore and 60 mm stroke. It features a rear adjustable stopper that trims up to 20 mm, giving a usable end-position window of 40-60 mm. The fixed rubber bumper absorbs end impact, and this non-magnet SKU cannot accept a position sensor.
The MALJ uses threaded covers and a PT tapered port thread, while the MBLJ upgrades to a riveted rolling-packed body. Remember 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 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 MBLJ20X60-20 carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |

| 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 MBLJ20X60-20 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-20 Is Used
Dispenser Nozzle Height Trim
Fine-tune the down position on a syringe-tip adhesive dispenser, shaving 5 mm off the 60 mm stroke to prevent nozzle crash on varying board heights.
Wire Cut-off Anvil Gap
Adjust the rear stopper to set a precise 45 mm anvil clearance on an automated wire cut-off machine, ensuring clean cuts without needing external spacers.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-20 with MBLJ20X60-20
To replace the MALJ20X60-20, order the MBLJ20X60-20. Confirm the 20 mm bore, 60 mm stroke, 20 mm adjust code, G1/8 port, and M8x1.25 rod-end thread. Mounting is Basic, FA, or LB only (no back-cover or SDB). Because this SKU lacks the -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if needed.
Upgrade checklist
- ✓ Order the MBLJ20X60-20 (same bore/stroke/adjust)
- ✓ Same 40–60 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 MBLJ20X60-20 instead of this discontinued model.
