This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-75, 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 MALJ32 Adjustable Mini Cylinder MALJ32X450-75

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-75
The AirTAC MALJ32X450-75 is a discontinued double-acting mini cylinder with a rear adjustable stroke. The direct replacement is the MBLJ32X450-75. It shares the same 32mm bore, 450mm stroke, G1/8 port, and 82 kgf max force. The -75 adjuster lets you trim the rear travel up to 75mm, creating a usable end-position window from 375mm to 450mm without adding external stops.
This SKU lacks the -S magnet option, so it cannot accept a position sensor. The original MALJ uses threaded covers and a fixed rubber bumper. The MBLJ upgrade shifts to a riveted rolling-packed body. Remember the adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure.

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 MBLJ32X450-75 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-75 Is Used
Printed Circuit Board Tester
Dial the 375-450mm reach to probe deep backplane connectors.
Long-Stroke Conveyor Diverter
Pivot a sorting gate across a 450mm belt path. The rear stop lets you fine-tune the retracted position to clear varying package widths.
Automated Drawer Indexing
Extend components out of an assembly rack. The fixed rubber bumper absorbs the end impact, while the stopper dials the exact open distance.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-75 with MBLJ32X450-75
To replace the MALJ32X450-75, order the exact MBLJ32X450-75 direct. Confirm the 32mm bore, 450mm stroke, -75 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 has no -S magnet, you lose sensor capability entirely. The MBLJ upgrade uses CMSG/DMSG/EMSG sensors, but only if you switch to an -S version. The adjuster sets the end position but does not lock the load.
With a 450mm stroke, the 12mm rod is prone to bending under side loads; guide the load externally to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ32X450-75 (same bore/stroke/adjust)
- ✓ Same 375–450 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 MBLJ32X450-75 instead of this discontinued model.
