This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X225-75, 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 MALJ20 Adjustable Mini Cylinder MALJ20X225-75
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 150 to 225 mm. This model is discontinued — the direct replacement is the MBLJ20X225-75.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-75
The AirTAC MALJ20X225-75 is a discontinued double-acting, double-rod mini cylinder with a 75 mm rear travel stop. It gives a usable extension window of 150-225 mm. The direct replacement is the MBLJ20X225-75, matching the bore, stroke, adjust code, G1/8 port, and mounting.
This SKU has no -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 end impact is softened by a fixed rubber bumper. The original MALJ uses threaded covers and the older CS1-M/DS1-M sensor family, while the current MBLJ features a riveted rolling-packed body and CMSG/DMSG/EMSG switches.

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 MBLJ20X225-75 carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | — |
| Max (@1.0 MPa) | 27 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 MBLJ20X225-75 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-75 Is Used
Dispense Valve Height
Fine-tune the retracted end position by up to 75 mm on a pneumatic dispensing valve head, allowing quick changes for different syringe barrel lengths without adding external mechanical stops.
Wire Termination Press
Adjust the stroke down from 225 mm to 150 mm to set the exact crimp height on an automated wire termination press, ensuring the 132 N pull force retracts the crimping anvil cleanly.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-75 with MBLJ20X225-75
To replace the MALJ20X225-75, order the exact direct replacement MBLJ20X225-75. Confirm the 20 mm bore, 225 mm stroke, 75 mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only; there is no back-cover or SDB option. Because this unit lacks the -S magnet, it cannot support a sensor; if you need tracking, step up to an MBLJ20X225-75S and use CMSG/DMSG/EMSG switches.
The 75 mm adjuster lets you dial the reach without external stops, but remember it is a stop, not a lock. At 225 mm stroke, keep side-load and rod-bending forces minimized to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ20X225-75 (same bore/stroke/adjust)
- ✓ Same 150–225 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 MBLJ20X225-75 instead of this discontinued model.
