This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X225-10, 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 MALJ40X225-10
The AirTAC MALJ40X225-10 is a discontinued double-acting double-rod cylinder with a rear adjustable stop. It trims up to 10 mm at the rear, giving a usable travel window of 215-225 mm. The direct replacement is the MBLJ40X225-10.
This SKU has no -S magnet, so it cannot take a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body.

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 MBLJ40X225-10 matches these values.

Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-10 with MBLJ40X225-10
To replace this MALJ with the MBLJ40X225-10, confirm the 40 mm bore, 225 mm stroke, 10 mm adjust code, PT G1/4 port, and FA/LB mounting (no back cover or SDB). Because this SKU lacks the -S magnet, you cannot mount a sensor; upgrading to an MBLJ-S version adds CMSG/DMSG/EMSG sensor support. At 225 mm, guard against rod side-load to prevent bending.
Upgrade checklist
- ✓ Order the MBLJ40X225-10 (same bore/stroke/adjust)
- ✓ Same 215–225 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 MBLJ40X225-10 instead of this discontinued model.
