This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X150-10, 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 MALJ20X150-10
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-10 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 140 to 150 mm. This model is discontinued — the direct replacement is the MBLJ20X150-10.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-10
The AirTAC MALJ20X150-10 is a discontinued double-acting, double-rod mini cylinder with a 20 mm bore and 150 mm stroke. The -10 adjust code provides a 10 mm rear trim, giving a usable end-position window of 140-150 mm. The direct replacement is the MBLJ20X150-10, matching the bore, stroke, adjust code, and G1/8 port.
This SKU lacks the -S magnet option, so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses a fixed rubber bumper and threaded covers, whereas the newer MBLJ features a riveted rolling-packed body. The original CS1-M/DS1-M sensors apply only to magnetized variants.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-10 Technical Specifications

| Adjustable window | 140 – 150 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |

| 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 MBLJ20X150-10 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 MBLJ20X150-10 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-10 Is Used
PCB Depaneling Saw
Dials the 140-150 mm blade plunge depth precisely.
Aluminum Extrusion Notcher
Trims the 10 mm rear stop to tune the cutting depth for varied profiles. The fixed rubber bumper absorbs the end impact during rapid cycling.
Small Parts Ejector Gate
Adjusts the 150 mm reach to clear different chute widths. The G1/8 port and 8 mm rod provide compact actuation for tight machine frames.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-10 with MBLJ20X150-10
To replace the MALJ20X150-10, use the MBLJ20X150-10. Confirm the 20 mm bore, 150 mm stroke, -10 adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot take a sensor. The MBLJ upgrade changes the switch family to CMSG/DMSG/EMSG if you need sensing. The adjuster sets the end position but does not hold the load without air.
For sizing, stepping down to a 12 mm bore lowers force, while stepping up to a 25 mm bore increases push force to 245 N at 0.5 MPa. At 150 mm stroke, the 8 mm rod is susceptible to side-load bending; ensure the load is guided to prevent rod distortion.
Upgrade checklist
- ✓ Order the MBLJ20X150-10 (same bore/stroke/adjust)
- ✓ Same 140–150 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 MBLJ20X150-10 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X150-10 FAQ
Yes, the MALJ20X150-10 is discontinued. The direct replacement is the MBLJ20X150-10, matching the 20 mm bore, 150 mm stroke, -10 adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The usable window is 140-150 mm, set by trimming the 10 mm rear stopper. The adjuster is a travel stop, not a lock, and cannot hold a load without live air.
