This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X35-20, 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 MALJ20X35-20
The AirTAC MALJ20X35-20 is a discontinued double-acting, adjustable-stroke mini cylinder. A rear screw lets you trim the end position by up to 20 mm, creating a usable reach window of 15-35 mm. The direct replacement is the MBLJ20X35-20, matching bore, stroke, force, and G1/8 port.
This unit uses a fixed rubber bumper, not an adjustable air cushion. 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. Because this SKU lacks the -S magnet, it cannot accept a position sensor. The legacy MALJ uses threaded covers and a carbon-steel rod with a 20 um hard chrome plating, whereas the MBLJ upgrade features a riveted rolling-packed body and switches to the CMSG/DMSG/EMSG sensor family if needed.

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 MBLJ20X35-20 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 MBLJ20X35-20 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X35-20 Is Used
PCB Edge Trimming Stops
Dial the rear stopper to set a precise 15-35 mm stroke window, positioning a cutting head over a conveyor without machining new hard stops.
Dispenser Nozzle Depth
Fine-tune the downward travel of an adhesive dispensing nozzle on a desktop assembly machine, using the rear screw to prevent nozzle crash.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X35-20 with MBLJ20X35-20
To replace the MALJ20X35-20, specify the MBLJ20X35-20 to keep the exact 20 mm bore, 35 mm stroke, 20 mm adjust code, G1/8 port, and FA/LB mounting (no back cover or SDB). Since this SKU has no -S magnet, it cannot take a sensor; the MBLJ upgrade requires CMSG/DMSG/EMSG switches if you add the -S option. Remember the adjuster is a stop, not a lock, so add an external lock for held loads.
As the smallest available MALJ bore, there is no smaller size down to step to.
Upgrade checklist
- ✓ Order the MBLJ20X35-20 (same bore/stroke/adjust)
- ✓ Same 15–35 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 MBLJ20X35-20 instead of this discontinued model.
