This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X10-10, 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 MALJ20X10-10
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 0 to 10 mm. This model is discontinued — the direct replacement is the MBLJ20X10-10.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10
The AirTAC MALJ20X10-10 is a discontinued double-acting mini cylinder with a 20mm bore and 10mm stroke. It features a rear travel stopper that allows you to trim up to 10mm, creating a usable end-position window of 0-10mm. The direct replacement is the MBLJ20X10-10, matching the bore, stroke, adjuster code, and G1/8 port.
This -10 adjuster sets the end position but does not hold a load without live air pressure. The original MALJ uses threaded covers and a fixed rubber bumper, while the current MBLJ upgrade features a riveted rolling-packed body. Because this specific SKU lacks a magnet (-S), it cannot accept a position sensor. If you need sensing, the MBLJ20X10-10S uses the modern CMSG/DMSG/EMSG switches.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10 Technical Specifications
| Model | Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ20X10-10 |
| Bore size | Ø20 mm |
| Stroke | 10 mm |
| Adjustable window | 0 – 10 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 mm |
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 MBLJ20X10-10 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 MBLJ20X10-10 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10 Is Used
Micro-fluidic valve stops
Set a precise travel limit on valve actuators where a 10mm maximum stroke prevents internal component damage.
Small-part pick-and-place
Adjust the retraction end-position on a 20mm bore cylinder to fine-tune the drop height for tiny electronic components.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10 with MBLJ20X10-10
To replace the MALJ20X10-10, order the MBLJ20X10-10. Confirm the 20mm bore, 10mm stroke, 10mm adjust code, PT G1/8 port, and M8x1.25 rod-end thread. Mounting is Basic, FA, or LB only; there is no back cover or SDB option. The adjuster is a travel stop, not a lock.
For any stroke over 300mm, prevent rod bending by guiding the load to avoid side-load.
Upgrade checklist
- ✓ Order the MBLJ20X10-10 (same bore/stroke/adjust)
- ✓ Same 0–10 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 MBLJ20X10-10 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10 FAQ
Yes, the MALJ20X10-10 is discontinued. The direct replacement is the MBLJ20X10-10, which matches the 20mm bore, 10mm stroke, 10mm adjuster, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design.
Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor. The MBLJ -S replacement uses CMSG/DMSG/EMSG switches.
