This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X150-100, 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 MALJ25X150-100
The AirTAC MALJ25X150-100 is a discontinued double-acting mini cylinder with a 25 mm bore and a 150 mm stroke. It provides a usable travel window of 50-150 mm via its 100 mm rear adjuster. The direct replacement is the MBLJ25X150-100, matching the bore, stroke, port and force.
This SKU has no -S magnet, so it cannot take a position sensor. The adjuster is a travel stop, not a lock. The original MALJ has threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body.

| Adjustable window | 50 – 150 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |

| 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 MBLJ25X150-100 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 MBLJ25X150-100 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-100 Is Used
PCB Router Depth Stop
Dial the end position between 50-150 mm to set precise Z-axis plunging depth on a PCB depaneling router without remounting hardware.
Pneumatic Press Tonnage
Fine-tune the bottoming position of a small pneumatic press to control crimp depth on brass terminals, using the bumper to soften impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-100 with MBLJ25X150-100
To replace this MALJ25X150-100, order the MBLJ25X150-100. Confirm the 25 mm bore, 150 mm stroke, 100 mm adjust code, G1/8 PT port, and FA/LB mounting. There is no back cover or SDB option. Since this SKU lacks an -S magnet, it cannot accept a sensor; if you need sensing on the new unit, specify an MBLJ-S to use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
Upgrade checklist
- ✓ Order the MBLJ25X150-100 (same bore/stroke/adjust)
- ✓ Same 50–150 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 MBLJ25X150-100 instead of this discontinued model.
