This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-40, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X100-40

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-40
The AirTAC MALJ25X100-40 is a discontinued 25mm bore, double-acting mini cylinder with a 100mm stroke and a 40mm rear adjustable stop. This gives a usable end-position window of 60-100mm, letting you fine-tune reach without adding external stops. The direct replacement is the MBLJ25X100-40, matching the bore, stroke, adjust code, and G1/8 port.
This SKU has no magnet (-S), 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 original MALJ uses threaded covers and fixed rubber bumpers, while the MBLJ upgrade features a riveted rolling-packed body. Mounting is FA or LB only; there is no back cover or SDB option.

Theoretical Output Force (Ø25mm)

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 MBLJ25X100-40 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-40 Is Used
Wire Cut-Off Clamp
Adjusts the retract distance on a wire cutting machine, providing a 60-100mm window to trim wire lengths accurately before the cut-off blade falls.
Carton Flap Folder
Fine-tunes the end position on a packaging line folder, using the 206N pull force to fold flaps at varying carton widths without swapping cylinders.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-40 with MBLJ25X100-40
To replace this MALJ25X100-40, order the MBLJ25X100-40. Confirm the 25mm bore, 100mm stroke, 40mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Since this is a no-S SKU, it cannot accept a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you add an -S model. The rear adjuster is a stop, not a lock. For any stroke over 300mm, mind rod-bending side loads.
Upgrade checklist
- ✓ Order the MBLJ25X100-40 (same bore/stroke/adjust)
- ✓ Same 60–100 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 MBLJ25X100-40 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-40 FAQ
Yes, the MALJ25X100-40 is discontinued. The direct replacement is the MBLJ25X100-40, which matches the 25mm bore, 100mm stroke, 40mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design, but the force and mounting remain the same.
The 40mm adjust code lets you trim the 100mm stroke at the rear, creating a usable end-position window of 60-100mm. The adjuster acts only as a travel stop and does not hold the load without live air.
