This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X80-20S, 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 MALJ32 Adjustable Mini Cylinder MALJ32X80-20-S
The AirTAC MALJ32X80-20-S is a discontinued double-acting mini cylinder with a rear adjustable stroke. The -20 code means you can trim up to 20 mm at the rear, giving a usable end-position window of 60-80 mm. The direct replacement is the MBLJ32X80-20-S, matching the bore, stroke, force, and port.
This -S SKU includes a magnet for CS1-M or DS1-M switches; the MBLJ upgrade switches to the CMSG/DMSG/EMSG family. The MALJ uses threaded covers, whereas the MBLJ features a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it sets the end position but will not hold a load without live air. End impact is softened by a fixed rubber bumper, 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 MBLJ32X80-20-S carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 MBLJ32X80-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-20-S Is Used
Aluminum Profile Stopper
Acts as an adjustable physical stop on a 90-degree transfer conveyor, letting operators trim the 20 mm reach to square up extruded frames before clamping.
Carton Flap Folder
Fine-tunes the folding arm position on packaging lines, absorbing the impact of heavy corrugated board against the fixed rubber bumper at the end of travel.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-20-S with MBLJ32X80-20-S
To replace this MALJ32X80-20-S, order the MBLJ32X80-20-S. Confirm the 32 mm bore, 80 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and basic mounting (no back cover or SDB). Remember the adjuster is a stop, not a lock. Your -S magnet requires changing from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors.
Since this 80 mm stroke is under the 300 mm threshold, rod-bending side-load risks are minimal.
Upgrade checklist
- ✓ Order the MBLJ32X80-20-S (same bore/stroke/adjust)
- ✓ Same 60–80 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 MBLJ32X80-20-S instead of this discontinued model.
