This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X100-75, 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 MALJ20X100-75

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-75
It features a rear screw stopper that trims up to 75mm, yielding a usable end-position window of 25-100mm. The direct replacement is the MBLJ20X100-75, matching the bore, stroke, force, and G1/8 port.
This SKU lacks a magnet (-S), so it 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. The original MALJ uses threaded covers and a fixed rubber bumper, whereas the MBLJ upgrade features a riveted rolling-packed body. Impact is softened by the bumper only, as there is no 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 MBLJ20X100-75 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 MBLJ20X100-75 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-75 Is Used
Dispenser Nozzle Depth
Fine-tunes the glue dispense height on an automotive gasket line, trimming the rear stopper to prevent crushing delicate housings.
Light Part Ejector
Adjusts the kick-out reach on a small electronics pick-and-place gantry to clear varying socket depths using the 132N pull force.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-75 with MBLJ20X100-75
To replace the MALJ20X100-75, order the MBLJ20X100-75. Confirm the 20mm bore, 100mm stroke, 75mm adjust code, G1/8 port, PT thread, and FA or LB mounting (no back cover or SDB is used). Since this SKU lacks the -S magnet, it cannot take a sensor; if you need sensing on the new unit, specify an MBLJ-S model which uses the newer CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster sets reach but does not lock the load.
At a 100mm stroke on an 8mm rod, watch for rod-bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ20X100-75 (same bore/stroke/adjust)
- ✓ Same 25–100 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 MBLJ20X100-75 instead of this discontinued model.
