This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X60-20S, 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 MALJ20X60-20S
The AirTAC MALJ20X60-20S is a discontinued double-acting double-rod mini cylinder with a 20mm rear adjustable stroke stopper. It provides a usable end-position window of 40-60mm. The direct replacement is the MBLJ20X60-20S.
This SKU includes a magnet (-S) for CS1-M or DS1-M switches. The MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors and replaces the original threaded covers with a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. A fixed rubber bumper softens end impacts without adjustable air cushioning.

| Max standard stroke | Up to 300 mm |
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 MBLJ20X60-20S 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 MBLJ20X60-20S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-20S Is Used
Dispenser Valve Height Trimming
Fine-tune the retracted position of a pneumatic glue dispenser by up to 20mm at the rear stopper, ensuring the nozzle clears varying substrate heights without remounting.
Small Part Ejector Stroke Limit
Restrict the ejection stroke of a plastic clip sorter to 40mm, using the rear screw to shorten the cycle and increase machine throughput without adding external stops.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-20S with MBLJ20X60-20S
To replace this MALJ20X60-20S, specify the MBLJ20X60-20S. Confirm the 20mm bore, 60mm stroke, 20mm adjust code, G1/8 port, PT thread, and FA/LB mounting. The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the adjuster sets the end position but does not lock the load.
At a 60mm stroke, rod side-load is minimal, but always ensure rigid rod-end alignment to prevent seal wear.
Upgrade checklist
- ✓ Order the MBLJ20X60-20S (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 MBLJ20X60-20S instead of this discontinued model.
