This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X80-100, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100
The AirTAC MALJ25X80-100 is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke. The 100mm adjuster lets you dial the end position back, creating a usable 0-80mm window. The direct replacement is the MBLJ25X80-100, matching the bore, stroke, force, and G1/8 port.
This SKU lacks the -S magnet, so it cannot take 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 fixed rubber bumper softens end impact. Upgrading to the MBLJ moves you from threaded covers to 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 MBLJ25X80-100 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100 Is Used
Carton Flap Folder
Adjust the rear stop on the fly to fold varying corrugated box heights, relying on the travel stop to set the precise resting position for the taping head.
Light-Press Pin Insertion
Press dowel pins into aluminum housings by tuning the stroke down from 80mm to exactly match the pin seat depth, preventing bottoming out against the casting.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100 with MBLJ25X80-100
To replace the MALJ25X80-100 with the MBLJ25X80-100, confirm the 25mm bore, 80mm stroke, 100mm adjust code, and PT G1/8 port. Mounting is FA or LB only; there is no back cover or SDB option. Because this SKU has no -S magnet, you cannot fit a sensor; if you need sensing, step up to an MBLJ-S model which uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
Upgrade checklist
- ✓ Order the MBLJ25X80-100 (same bore/stroke/adjust)
- ✓ Same -20–80 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 MBLJ25X80-100 instead of this discontinued model.
