This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X150-50, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50
The AirTAC MALJ25X150-50 is a discontinued double-acting mini cylinder with a rear travel stop. It gives a usable 100-150 mm stroke window by trimming up to 50 mm off the rear position. It uses a fixed rubber bumper, not an adjustable cushion.
The direct replacement is the MBLJ25X150-50, keeping the same G1/8 port, M10x1.25 rod thread, and FA/LB mounting. This SKU lacks the -S magnet, so it cannot take a position sensor. The older MALJ uses threaded covers and CS1-M/DS1-M switches, while the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50 Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50 |

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X150-50 |
| Bore size | Ø25 mm |
| Stroke | 150 mm |
| Adjustable window | 100 – 150 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 MBLJ25X150-50 carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 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 MBLJ25X150-50 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50 Is Used
PCB Router Depth Stop
Dial the end position within the 100-150 mm window to set precise Z-axis plunge depth for a PCB depaneling router, preventing bit damage without remounting hardware.
Label Wipe Brush
Set the retract stop to float a wipe brush against moving packaging, ensuring consistent label adhesion without overpowering the 206 N pull force.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50 with MBLJ25X150-50
To replace this MALJ25X150-50, order the direct replacement MBLJ25X150-50. Confirm your 25 mm bore, 150 mm stroke, 50 mm adjust code, PT G1/8 port, and FA/LB mount. There is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot hold a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches. The rear adjuster is a travel stop, not a lock, so add an external lock to hold loads without air.
At 150 mm stroke, the extended rod is prone to bending under side loads, so guide the load to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ25X150-50 (same bore/stroke/adjust)
- ✓ Same 100–150 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 MBLJ25X150-50 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50 FAQ
Yes, the MALJ25X150-50 is discontinued. The direct replacement is the MBLJ25X150-50, which matches the 25 mm bore, 150 mm stroke, 50 mm adjust code, G1/8 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M.
The 50 mm adjust code lets you trim the rear position, creating a usable 100-150 mm stroke window. The adjuster is a travel stop, not a lock. This no-S SKU lacks a magnet and cannot take a sensor.
