This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X150-100, 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).

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-100
The AirTAC MALJ20X150-100 is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It trims up to 100 mm at the rear, yielding a usable end-position window of 50-150 mm. The direct replacement is the MBLJ20X150-100, matching bore, stroke, force, G1/8 port, and mounting.
This SKU lacks the -S magnet code, so it cannot accept a position sensor. The original MALJ uses threaded covers and a fixed rubber bumper; the MBLJ upgrade features a riveted rolling-packed body. Remember that the rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure.

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 MBLJ20X150-100 carries the same ratings.
Theoretical Output Force (Ø20mm)

| 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 MBLJ20X150-100 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-100 Is Used
Dispenser Nozzle Height Trim
Adjust the end position down to a 50 mm window for an adhesive dispenser nozzle, ensuring precise dot placement on uneven electronic substrates.
Lightweight Parts Ejector
Fine-tune the ejection stroke on a small plastic injection mold to release delicate parts gently, relying on the fixed rubber bumper to soften the end impact.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-100 with MBLJ20X150-100
To replace the MALJ20X150-100, order the direct replacement MBLJ20X150-100. Confirm the 20 mm bore, 150 mm stroke, 100 mm adjust code, G1/8 port, PT thread, and FA or LB mounting (no back cover or SDB is supported). Because this SKU lacks the -S magnet, it cannot take a sensor; if you need position detection, step up to an MBLJ20X150-100S model and use CMSG/DMSG/EMSG switches instead of the old CS1-M/DS1-M.
At a 150 mm stroke, the 8 mm rod is susceptible to bending under side loads; keep the load axially guided to prevent rod damage. The rear adjuster is a stop, not a lock, so add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ20X150-100 (same bore/stroke/adjust)
- ✓ Same 50–150 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 MBLJ20X150-100 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-100 FAQ
Yes, the MALJ20X150-100 is discontinued. The direct replacement is the MBLJ20X150-100, which matches the 20 mm bore, 150 mm stroke, 100 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
At 0.7 MPa, push is 220 N, with a maximum of 32 kgf at 1.0 MPa. The 100 mm adjust code allows you to trim the rear stroke by up to 100 mm, creating a usable stroke window of 50-150 mm. The adjuster is a travel stop, not a lock.
