This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X200-30, 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).
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30 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 170 to 200 mm. This model is discontinued — the direct replacement is the MBLJ20X200-30.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30
The AirTAC MALJ20X200-30 is a discontinued double-acting double-rod mini cylinder with a 20mm bore and 200mm stroke. It is superseded by the direct replacement MBLJ20X200-30, which matches the bore, stroke, force, and G1/8 port. The -30 adjust code means you can trim up to 30mm at the rear screw, giving a usable extension window of 170-200mm.
The rear adjuster functions purely as a travel stop to set the end position; it does not hold a load without live air. This SKU lacks the -S magnet, so it cannot accept a position sensor. During the upgrade, the older threaded covers and CS1-M/DS1-M switches are replaced by a riveted rolling-packed body and CMSG/DMSG/EMSG sensors on the MBLJ. Impact is absorbed by a fixed rubber bumper, not an 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 MBLJ20X200-30 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 MBLJ20X200-30 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30 Is Used
Dispenser Valve Profiling
Fine-tunes the 170-200mm reach for a pneumatic adhesive dispenser, ensuring the nozzle clears tall housings before applying epoxy.
Small Parts Ejector
Trims the extension on an injection mold ejector to drop small plastic clips at exactly 185mm, avoiding stress on the 8mm rod.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30 with MBLJ20X200-30
To replace the MALJ20X200-30, order the direct replacement MBLJ20X200-30. Confirm the 20mm bore, 200mm stroke, 30mm adjust code, PT G1/8 port, and M8x1.25 rod-end thread. Mounting is Basic, FA, or LB only (no back cover or SDB). Because this SKU has no -S magnet, it cannot take a sensor; if you need sensing, step up to an MBLJ20X200-30S and use CMSG/DMSG/EMSG switches.
The 200mm stroke is standard for this bore. Remember the rear adjuster is a travel stop, not a lock; use an external lock for held loads. On this 200mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ20X200-30 (same bore/stroke/adjust)
- ✓ Same 170–200 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 MBLJ20X200-30 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-30 FAQ
