This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-30, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X100-30
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X100-30 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 70 to 100 mm. This model is discontinued — the direct replacement is the MBLJ25X100-30.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-30
The AirTAC MALJ25X100-30 is a discontinued double-acting mini cylinder with a 25mm bore and 100mm stroke. It features a rear screw stopper that lets you trim up to 30mm of travel, giving a usable end-position window of 70-100mm. The direct replacement is the MBLJ25X100-30, which matches the force, G1/8 port, and mounting.
This SKU lacks the -S magnet code, so it cannot accept a position sensor. The MALJ uses a fixed rubber bumper, not an adjustable air cushion, and the rear adjuster is a travel stop, not a load lock. Upgrading to the MBLJ25X100-30 changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG and swaps the threaded covers for a riveted rolling-packed body.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-30 Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-30 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X100-30 |
| Bore size | Ø25 mm |
| Stroke | 100 mm |
| Adjustable window | 70 – 100 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 MBLJ25X100-30 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 MBLJ25X100-30 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-30 Is Used
PCB Router Z-Axis Depth
Dial in the 70-100mm travel window to set the exact cutting depth on a printed circuit board routing spindle without adding external mechanical stops.
Wire Straightener Tensioner
Apply 206N of pull force to tension a wire straightening die, adjusting the end position to accommodate varying wire diameters on the fly.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-30 with MBLJ25X100-30
To replace the MALJ25X100-30, select the MBLJ25X100-30. Confirm the 25mm bore, 100mm stroke, 30mm adjust code, and G1/8 PT port. Mounting is FA or LB only, as there is no back-cover or SDB option. Because this SKU has no -S magnet, it cannot take a sensor; if you need sensing, the MBLJ replacement requires CMSG/DMSG/EMSG switches. Remember the adjuster sets the end position but does not hold load without live air.
Since the stroke is 100mm, watch for rod-bending on side loads; keep the load guided to prevent binding.
Upgrade checklist
- ✓ Order the MBLJ25X100-30 (same bore/stroke/adjust)
- ✓ Same 70–100 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 MBLJ25X100-30 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-30 FAQ
Yes, the MALJ25X100-30 is discontinued. The direct replacement is the MBLJ25X100-30, which matches the 25mm bore, 100mm stroke, 30mm adjust code, force, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if needed.
The -30 adjust code lets you trim up to 30mm at the rear, creating a 70-100mm usable window. The adjuster is a travel stop, not a lock; it will not hold a load without continuous air pressure.
