This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X160-75, 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 MALJ20X160-75
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 85 to 160 mm. This model is discontinued — the direct replacement is the MBLJ20X160-75.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-75
The AirTAC MALJ20X160-75 is a discontinued double-acting, double-rod mini cylinder with a 20mm bore and a 160mm stroke. It features a rear adjustable-stroke stopper that trims up to 75mm, giving a usable end-position window of 85-160mm. The direct replacement is the MBLJ20X160-75, matching the bore, stroke, force, and G1/8 port. This SKU has no magnet and cannot accept a position sensor.
The rear adjuster sets travel limits but is a stop, not a lock—it will not hold a load without live air. Unlike the riveted rolling-packed body of the MBLJ, the MALJ uses threaded covers. End impact is absorbed by 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 does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ20X160-75 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 MBLJ20X160-75 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-75 Is Used
PCB Router Depth Stop
Dials the final 85-160mm reach on a depaneling fixture.
Label Applicator Tamp
Fine-tunes the tamp stroke on a bottle labeling head. Trimming 75mm at the rear prevents label crush on varying container diameters without adding external physical stops.
Wire Harness Crimp
Sets the exact end position for a terminal crimp press. The 132N pull at 0.5MPa retracts the tooling cleanly, while the rear stop maintains consistent crimp depth across material thicknesses.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-75 with MBLJ20X160-75
To replace the MALJ20X160-75, install the direct replacement MBLJ20X160-75. Confirm the 20mm bore, 160mm stroke, 75mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The MBLJ upgrade switches the body to a riveted rolling-packed design from the original threaded covers. Since this SKU lacks the -S magnet, it cannot take a sensor; if you need sensing on the new unit, add the -S code to use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
Remember the adjuster is a travel stop, not a lock; use an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ20X160-75 (same bore/stroke/adjust)
- ✓ Same 85–160 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 MBLJ20X160-75 instead of this discontinued model.
