This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X225-20, 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 MALJ20X225-20
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 205 to 225 mm. This model is discontinued — the direct replacement is the MBLJ20X225-20.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-20
The AirTAC MALJ20X225-20 is a discontinued 20mm bore, double-acting double-rod mini cylinder with a rear adjustable stroke. It trims up to 20mm at the rear, giving a usable end-position window of 205-225mm. The direct replacement is the MBLJ20X225-20, which matches the bore, stroke, force, G1/8 port and mounting.
This SKU lacks the -S magnet option, 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. Upgrading to the MBLJ moves you from threaded covers to a riveted rolling-packed body. Impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.

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 MBLJ20X225-20 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 MBLJ20X225-20 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-20 Is Used
Dispense Valve Depth Stop
Sets a precise 205mm reach into a fluid cartridge, preventing bottoming-out while the fixed rubber bumper softens the stop.
Wire Cutter Profiler
Trims the stroke window to 215mm for varying harness lengths, relying on the 8mm rod and external guides for straight cuts.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-20 with MBLJ20X225-20
To replace the MALJ20X225-20, order the MBLJ20X225-20. Confirm your G1/8 port, M8x1.25 rod-end thread, and FA or LB mounting (there is no back cover or SDB option). Because this SKU has no -S magnet, you lose the old CS1-M / DS1-M sensors; the MBLJ upgrade uses CMSG / DMSG / EMSG switches if you need them. The rear adjuster is a stop, not a lock.
At 225mm stroke, the 8mm rod is highly susceptible to side-load bending; use rigid guidance to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ20X225-20 (same bore/stroke/adjust)
- ✓ Same 205–225 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 MBLJ20X225-20 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X225-20 FAQ
Yes, the MALJ20X225-20 is discontinued. The direct replacement is the MBLJ20X225-20, matching the 20mm bore, 225mm stroke, 20mm adjuster, G1/8 port and force. The MBLJ upgrades the body to a riveted rolling-packed design from the old threaded covers.
The 20mm adjuster creates a usable stroke window of 205-225mm. Remember the adjuster is a travel stop, not a lock, and this no-S SKU cannot take a sensor.
