This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X110-20, 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 MALJ40 Adjustable Mini Cylinder MALJ40X110-20
The AirTAC MALJ40X110-20 is a discontinued double-acting double-rod cylinder with a 40mm bore and 110mm stroke. The rear screw stopper lets you trim up to 20mm, giving an exact usable end-position window of 90-110mm. The direct replacement is the MBLJ40X110-20, matching the bore, stroke, G1/4 port, and mounting.
This SKU has no -S magnet and cannot take a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but holds no 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.

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 MBLJ40X110-20 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X110-20 Is Used
Forming Pin Locator
Adjust the end position on a sheet metal forming line to locate pins precisely, relying on the 16mm rod to resist deflection during the hit.
Packaging Depth Stop
Tune the rear 20mm adjuster on a carton flap folder to handle varying box heights without swapping hardware, using the fixed rubber bumper to soften impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X110-20 with MBLJ40X110-20
To replace the MALJ40X110-20, order the MBLJ40X110-20. Confirm the 40mm bore, 110mm stroke, 20mm adjust code, G1/4 port, PT thread, and FA or LB mounting (no back cover or SDB allowed). Since this SKU lacks the -S magnet, it cannot accept a sensor; upgrading to an MBLJ-S gets you the modern CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M. Remember the adjuster is a stop, not a lock.
The 40mm is the largest available MALJ bore.
Upgrade checklist
- ✓ Order the MBLJ40X110-20 (same bore/stroke/adjust)
- ✓ Same 90–110 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 MBLJ40X110-20 instead of this discontinued model.
