This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-20, 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 MALJ25X100-20
The AirTAC MALJ25X100-20 is a discontinued double-acting mini cylinder with a 20mm rear adjustable stroke stopper. It gives a usable extension window of 80-100mm. The direct replacement is the MBLJ25X100-20, matching the 100mm stroke, 20mm adjuster, G1/8 port, and 50kgf max force.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The rear adjuster sets the end position but does not hold load without live air. It uses a fixed rubber bumper, not an adjustable air cushion. The original MALJ has threaded covers, while the MBLJ upgrade features a riveted rolling-packed body for better sealing.

| Replacement | MBLJ25X100-20 |
| Bore size | Ø25 mm |
| Stroke | 100 mm |
| Adjustable window | 80 – 100 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 MBLJ25X100-20 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 MBLJ25X100-20 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-20 Is Used
PCB Router Z-Axis
Dial in the 80-100mm reach on a PCB depaneling router to cut exactly through the substrate without stressing the panel.
Dispenser Valve Depth
Set the precise 80-100mm stroke on an adhesive dispenser to lower the needle just above the workpiece without dripping.
Wire Cut Forming
Trim the 100mm stroke by up to 20mm to tune the wire cutoff blade depth on an automated forming machine.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-20 with MBLJ25X100-20
To replace this MALJ25X100-20, order the exact MBLJ25X100-20 direct. Confirm the 25mm bore, 100mm stroke, 20mm adjust code, PT G1/8 port, and FA/LB mounting (no back cover or SDB). Because this SKU has no -S magnet, it cannot take a sensor; upgrading to an MBLJ-S switches you to CMSG/DMSG/EMSG switches from the old CS1-M/DS1-M family. The adjuster is a travel stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ25X100-20 (same bore/stroke/adjust)
- ✓ Same 80–100 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 MBLJ25X100-20 instead of this discontinued model.
