This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X180-75, 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).

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X180-75
The AirTAC MALJ40X180-75 is a discontinued double-acting mini cylinder with a rear adjustable stroke stopper. Its 75mm adjuster trims the end position, giving a usable reach window of 105-180mm. The direct replacement is the MBLJ40X180-75.
This SKU has no magnet and cannot accept a position sensor. The adjuster is a travel stop, not a lock, so it will not hold a load without live air. Upgrading to the MBLJ moves you from threaded covers to a riveted rolling-packed body. Both generations use a fixed rubber bumper, not an adjustable air cushion.

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 MBLJ40X180-75 matches these values.

Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X180-75 with MBLJ40X180-75
Replace this MALJ40X180-75 with the MBLJ40X180-75. Confirm the 40mm bore, 180mm stroke, 75mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB allowed). Since this SKU lacks the -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you add one. The adjuster sets end position but does not hold load without air.
At 180mm stroke, watch rod-to-side-load bending on the 16mm rod.
Upgrade checklist
- ✓ Order the MBLJ40X180-75 (same bore/stroke/adjust)
- ✓ Same 105–180 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 MBLJ40X180-75 instead of this discontinued model.
