This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X75-10, 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 MALJ20X75-10
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10 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 65 to 75 mm. This model is discontinued — the direct replacement is the MBLJ20X75-10.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10
The AirTAC MALJ20X75-10 is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. It has a 20mm bore, a 75mm stroke, and a 10mm rear adjuster, giving a usable end-position window of 65-75mm. The direct replacement is the MBLJ20X75-10, matching the bore, stroke, adjuster, G1/8 port, and mounting.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The rear adjuster is a travel stop to fine-tune reach without external hardware; it is not a lock and will not hold a load without live air. The fixed rubber bumper softens end impact. Note the upgrade path: the MALJ uses threaded covers and the older CS1-M/DS1-M sensor family, while the MBLJ uses a riveted rolling-packed body and CMSG/DMSG/EMSG switches.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10 Technical Specifications
| Model | Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ20X75-10 |
| Bore size | Ø20 mm |
| Stroke | 75 mm |
| Adjustable window | 65 – 75 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 MBLJ20X75-10 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 MBLJ20X75-10 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10 Is Used
PCB Router Z-Axis Stop
Dial in the 65-75mm descent on a PCB depaneling router.
Dispenser Valve Height
Fine-tune the drop height for an epoxy dispensing valve. The 10mm rear adjuster lets you set the exact nozzle clearance without machining new brackets.
Lead Trimmer Strike
Trim through-hole component leads on a sequencer. The 132N pull force retracts the cutter cleanly, while the rubber bumper absorbs the impact of the rapid 800 mm/s cycle.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10 with MBLJ20X75-10
To replace this MALJ20X75-10, order the MBLJ20X75-10. Confirm the 20mm bore, 75mm stroke, 10mm adjust code, G1/8 port, PT thread, and FA/LB mounting (there is no back-cover or SDB option). Because this SKU lacks the -S magnet, it cannot take a sensor; if you need position detection, specify an MBLJ20X75-10S and use CMSG/DMSG/EMSG switches. The rear adjuster sets the end position but does not hold load without air; use an external lock for held loads. At 75mm, the stroke is moderate, but always ensure the rod is guided to prevent bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ20X75-10 (same bore/stroke/adjust)
- ✓ Same 65–75 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 MBLJ20X75-10 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10 FAQ
Yes, the MALJ20X75-10 is discontinued. The direct replacement is the MBLJ20X75-10, which matches the 20mm bore, 75mm stroke, 10mm adjuster, G1/8 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add the -S magnet option.
The 10mm rear adjuster creates a usable stroke window of 65-75mm. The adjuster is a travel stop, not a lock; it cannot hold a load without live air. This SKU has no magnet, so it cannot accept a position sensor.
