This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X55-20, 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 MALJ32X55-20
The AirTAC MALJ32X55-20 is a discontinued double-acting double-rod mini cylinder with a 32 mm bore and 55 mm stroke. It features a rear adjuster that lets you trim the end position by up to 20 mm, creating a usable stroke window of 35-55 mm without adding external stops. The direct replacement is the MBLJ32X55-20, matching the bore, stroke, force, G1/8 port, and mounting.
This SKU lacks the -S magnet option, so it cannot accept a position sensor. The MALJ uses threaded covers and a fixed rubber bumper to soften end impact, whereas the MBLJ replacement features a riveted rolling-packed body. Remember that 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 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 MBLJ32X55-20 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 MBLJ32X55-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-20 Is Used
Carton Flap Folder
Fine-tune the rear stopper on a packaging line flap folder to perfectly tuck varying cardboard thicknesses, relying on the fixed rubber bumper to absorb rapid cycling impacts.
Wire Harness Forming Jig
Adjust the end position on an automotive wire harness jig to bend cables into specific profiles without bolting on external physical stops to the fixture.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-20 with MBLJ32X55-20
To replace the MALJ32X55-20, order the exact direct replacement MBLJ32X55-20. Confirm the 32 mm bore, 55 mm stroke, 20 mm adjust code, PT G1/8 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. If you need a sensor on the new unit, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M family. The adjuster is a stop, not a lock.
The 55 mm stroke is well within standard limits, so no side-load rod-bending concerns apply here.
Upgrade checklist
- ✓ Order the MBLJ32X55-20 (same bore/stroke/adjust)
- ✓ Same 35–55 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 MBLJ32X55-20 instead of this discontinued model.
