This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X225-50, 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 MALJ20X225-50

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-50
The AirTAC MALJ20X225-50 is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It features a 20mm bore and a 225mm stroke, but the rear adjuster lets you trim up to 50mm, giving a usable end-position window of 175-225mm. The direct replacement is the MBLJ20X225-50, matching the bore, stroke, force, and port.
This SKU lacks a 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 MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body.

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 MBLJ20X225-50 carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |

| 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 MBLJ20X225-50 matches these values.

Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-50 with MBLJ20X225-50
To replace this MALJ20X225-50, order the direct replacement MBLJ20X225-50. Confirm the 20mm bore, 225mm stroke, 50mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only (no back cover or SDB allowed). Since this SKU has no magnet, you lose the old CS1-M/DS1-M switches; the MBLJ upgrade uses CMSG/DMSG/EMSG sensors. The adjuster sets travel but is not a lock.
At 225mm stroke, watch for rod-bending on long strokes; use a guide to prevent side-load damage.
Upgrade checklist
- ✓ Order the MBLJ20X225-50 (same bore/stroke/adjust)
- ✓ Same 175–225 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 MBLJ20X225-50 instead of this discontinued model.
