This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X75-30FA, 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 MALJ25X75-30FA
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X75-30FA is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 45 to 75 mm. This model is discontinued — the direct replacement is the MBLJ25X75-30FA.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-30FA
The AirTAC MALJ25X75-30FA is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It has a 25mm bore, 75mm stroke, and a 30mm adjust code, giving a usable end-position window of 45-75mm. The direct replacement is the MBLJ25X75-30FA, matching bore, stroke, port, and FA flange.
This FA flange-mounted unit uses a G1/8 port and an M10x1.25 rod-end thread. 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, but this is not an adjustable cushion. As this SKU lacks the -S magnet, it cannot take a position sensor. The original MALJ uses threaded covers and CS1-M/DS1-M switches; the MBLJ upgrade uses a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.

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 MBLJ25X75-30FA carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 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 MBLJ25X75-30FA matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-30FA Is Used
Carton Flap Plow
Tune the end position on a case erector's flap plow to 60mm, matching carton height variations without swapping hardware, while the fixed rubber bumper absorbs the 206N pull impact.
Label Wipe Brush
Adjust the rear stopper to 50mm reach on a bottle labeling line, letting the brush wipe labels consistently without relocating the FA flange bracket.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-30FA with MBLJ25X75-30FA
Replace the MALJ25X75-30FA with the exact direct replacement MBLJ25X75-30FA, confirming the 25mm bore, 75mm stroke, 30mm adjust code, G1/8 port, PT thread, and FA flange mounting (no back cover or SDB). Because this SKU lacks the -S magnet, it cannot accept a sensor; upgrading to MBLJ25X75-30FAS adds the magnet and moves you to the CMSG/DMSG/EMSG switch family. Remember the adjuster is a stop, not a lock, so add an external lock for held loads.
At 75mm stroke, keep rod side-load minimal to avoid bending the 10mm rod.
Upgrade checklist
- ✓ Order the MBLJ25X75-30FA (same bore/stroke/adjust)
- ✓ Same 45–75 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 MBLJ25X75-30FA instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-30FA FAQ
Yes, the MALJ25X75-30FA is discontinued. The direct replacement is the MBLJ25X75-30FA, which matches the 25mm bore, 75mm stroke, 30mm adjust code, G1/8 port, and FA flange. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add the -S magnet.
The 30mm adjust code allows you to trim the 75mm stroke rearward, giving a usable end-position window of 45-75mm. The adjuster is a travel stop only and does not hold load without air.
