This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X80-20, 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
The AirTAC MALJ32X80-20 is a discontinued 32mm bore, double-acting mini cylinder with a 20mm rear adjustable stroke stopper. The direct replacement is the MBLJ32X80-20, matching the bore, stroke, adjuster code, G1/8 port, and FA/LB mounting options.
This non-magnet SKU lacks a -S code and cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure. The original MALJ uses threaded covers and a fixed rubber bumper, while the current MBLJ upgrade features a riveted rolling-packed body.

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 carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 346 N | 346 N |
| 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 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-20 Is Used
Carton Flap Folder
Fine-tune the folding arm reach on a packaging line; the rear stopper lets you trim up to 20mm to compensate for varying cardboard thicknesses without adding external spacers.
Pneumatic Press Locator
Position a small 32mm bore locator pin against an aluminum housing, adjusting the end position by a few millimeters to align parts before the main 563N clamping action fires.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-20 with MBLJ32X80-20
To replace the MALJ32X80-20, order the exact MBLJ32X80-20. Confirm the 32mm bore, 80mm stroke, 20mm adjust code, G1/8 PT port, and M10x1.25 rod-end thread. Mounting is FA or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot take a sensor, whereas upgrading to an MBLJ-S allows modern CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M.
The 20mm adjuster is a travel stop, not a lock; use an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ32X80-20 (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 instead of this discontinued model.
