This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X60-40S, 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 MALJ20X60-40S

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-40S
The AirTAC MALJ20X60-40S is a discontinued double-acting, double-rod mini cylinder with a 20mm bore and 60mm stroke. It features a 40mm rear adjuster, providing a usable end-position window of 20-60mm. The direct replacement is the MBLJ20X60-40S, matching bore, stroke, and force.
The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. This MALJ has threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. The -S magnet on this unit works with CS1-M/DS1-M switches, whereas the MBLJ uses CMSG/DMSG/EMSG sensors. Port is G1/8.

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 MBLJ20X60-40S 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 MBLJ20X60-40S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-40S Is Used
Connector Pin Insertion
Set a 40mm travel stop to insert delicate header pins into plastic housings, using the fixed rubber bumper to soften the end impact.
Light-Actuator Gate
Adjust the 60mm stroke window to trigger micro-limit arms on a packaging line, ensuring exact timing without needing external stops.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-40S with MBLJ20X60-40S
Replace this MALJ20X60-40S directly with the MBLJ20X60-40S. Confirm the 20mm bore, 60mm stroke, 40mm adjust code, G1/8 port, and M8x1.25 rod thread. Mounting is FA or LB only (no back cover or SDB). The rear adjuster sets end position but is not a lock; use an external lock for held loads. The -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG on the MBLJ.
Upgrade checklist
- ✓ Order the MBLJ20X60-40S (same bore/stroke/adjust)
- ✓ Same 20–60 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 MBLJ20X60-40S instead of this discontinued model.
