This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X150-20S, 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 MALJ20X150-20-S

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-20-S
The AirTAC MALJ20X150-20-S is a discontinued adjustable-stroke mini cylinder. It is double-acting with a double rod, an 8mm carbon-steel rod, and a G1/8 port. The -20 code means you can trim up to 20mm at the rear screw stopper, creating a usable end-position window from 130mm to 150mm. The direct replacement is the MBLJ20X150-20-S.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. This SKU includes the -S magnet, which on the MALJ works with CS1-M/DS1-M switches, while the MBLJ replacement uses CMSG/DMSG/EMSG sensors. The MALJ has threaded covers and a fixed rubber bumper; the MBLJ upgrades to a riveted rolling-packed body. There is no back cover or SDB option; mounting is Basic, FA, or LB only.

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 MBLJ20X150-20-S 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 MBLJ20X150-20-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-20-S Is Used
Dispenser Nozzle Height Trim
Fine-tune the retraction end position on an adhesive dispenser to prevent nozzle crash, trimming up to 20mm at the rear stopper for exact fluid dot placement.
Leather Press Tonnage Check
Use the 132N pull force on a small leather embossing press to test material yield, adjusting the stroke window to clear different die thicknesses quickly.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-20-S with MBLJ20X150-20-S
To replace this MALJ20X150-20-S, order the MBLJ20X150-20-S. Confirm the 20mm bore, 150mm stroke, -20 adjust code, PT G1/8 port, and M8x1.25 rod thread. Mounting remains FA or LB with no back cover. You must also change your sensors: the old CS1-M/DS1-M switches are replaced by CMSG/DMSG/EMSG on the MBLJ. Remember the adjuster is a stop, not a lock, so add an external lock for held loads.
At a 150mm stroke, keep the rod guided to prevent side-load bending, as long strokes amplify rod deflection.
Upgrade checklist
- ✓ Order the MBLJ20X150-20-S (same bore/stroke/adjust)
- ✓ Same 130–150 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 MBLJ20X150-20-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-20-S FAQ
Yes, the MALJ20X150-20-S is discontinued. The direct replacement is the MBLJ20X150-20-S, keeping the same 20mm bore, 150mm stroke, -20 adjust code, G1/8 port, and mounting. You only need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The -20 adjust code lets you trim up to 20mm at the rear, giving a usable stroke window from 130mm to 150mm. The adjuster is a travel stop, not a lock.
