This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X75-50, 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 MALJ32X75-50
The AirTAC MALJ32X75-50 is a discontinued double-acting, double-rod mini cylinder with a 32 mm bore and 75 mm stroke. The rear adjuster lets you trim the end position by up to 50 mm, creating a usable stroke window of 25-75 mm. The direct replacement is the MBLJ32X75-50, matching the bore, stroke, force, and port.
This SKU has no magnet (-S omitted), so it 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. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. End impact is softened by the bumper only—there is no 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 MBLJ32X75-50 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 MBLJ32X75-50 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X75-50 Is Used
Bottle Flange Trimmer
Adjust the rear stop to tune the 75 mm extension, ensuring the 346 N pull force retracts the trimmer blade cleanly without over-travel.
Carton Flap Folder
Fine-tune the end position to match varying carton heights, using the fixed rubber bumper to absorb the impact of the folding arm at stroke end.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X75-50 with MBLJ32X75-50
To replace the MALJ32X75-50, order the MBLJ32X75-50. Confirm the 32 mm bore, 75 mm stroke, 50 mm adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only—there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot take a sensor; upgrading to an MBLJ with -S moves you to the CMSG/DMSG/EMSG switch family. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X75-50 (same bore/stroke/adjust)
- ✓ Same 25–75 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 MBLJ32X75-50 instead of this discontinued model.
