This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X60-30, 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 MALJ25X60-30
The AirTAC MALJ25X60-30 is a discontinued adjustable-stroke mini cylinder. The direct replacement is the MBLJ25X60-30, matching the 25mm bore, 60mm stroke, 30mm adjuster range, G1/8 port and mounting footprint. The rear adjuster allows you to trim up to 30 mm of travel, creating a usable stroke window of 30-60 mm to fine-tune the end position without external stops.
This SKU lacks the -S magnet option, so it cannot accept 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 pressure. Impact is softened by a fixed rubber bumper, meaning there is no adjustable air cushion. The legacy MALJ uses threaded covers and older CS1-M/DS1-M sensors, while the MBLJ25X60-30 upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG switches. Mounting is limited to FA or LB, with no back cover or SDB options.

The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ25X60-30 carries the same ratings.
Theoretical Output Force (Ø25mm)

| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 kgf | |
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 MBLJ25X60-30 matches these values.

Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-30 with MBLJ25X60-30
To replace the MALJ25X60-30, order the exact direct replacement MBLJ25X60-30. Confirm the 25mm bore, 60mm stroke, 30mm adjust code, G1/8 port, PT thread, and FA/LB mounting. The MBLJ keeps the same force ratings but upgrades the body to a riveted rolling-packed design. Remember the rear adjuster is a travel stop, not a lock; you still need live air or an external lock to hold a load.
Upgrade checklist
- ✓ Order the MBLJ25X60-30 (same bore/stroke/adjust)
- ✓ Same 30–60 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 MBLJ25X60-30 instead of this discontinued model.
