This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-100, 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).
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-100
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X100-100 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 0 to 100 mm. This model is discontinued — the direct replacement is the MBLJ25X100-100.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-100
The AirTAC MALJ25X100-100 is a discontinued double-acting, double-rod mini cylinder with a 25 mm bore and 100 mm stroke. A rear adjuster lets you trim up to 100 mm, giving a usable end-position window of 0-100 mm. The direct replacement is the MBLJ25X100-100, matching bore, stroke, force, and G1/8 port.
This SKU has no magnet, so it cannot take a position sensor. The adjuster is a travel stop, not a lock, and the fixed rubber bumper softens end impact without providing air cushioning. Upgrading to the MBLJ25X100-100 moves you from threaded covers to a riveted rolling-packed body; if you need sensors later, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.

| Replacement | MBLJ25X100-100 |
| Bore size | Ø25 mm |
| Stroke | 100 mm |
| Adjustable window | 0 – 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 MBLJ25X100-100 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 MBLJ25X100-100 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-100 Is Used
Cartesian Dispenser Probe
Fine-tune the exact dispensing height for a fluid syringe probe without re-homing the axis, relying on the 206 N pull to retract the tool safely.
Leather Press Creaser
Adjust the stroke on a leather embossing press to switch material thicknesses, letting the fixed rubber bumper absorb the 0.5 MPa impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-100 with MBLJ25X100-100
To replace the MALJ25X100-100, order the exact direct replacement MBLJ25X100-100. Confirm the 25 mm bore, 100 mm stroke, 100 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (there is no back cover or SDB option). Because this SKU lacks the -S magnet, it cannot accept a sensor. The adjuster sets end position but does not hold load without live air.
Upgrade checklist
- ✓ Order the MBLJ25X100-100 (same bore/stroke/adjust)
- ✓ Same 0–100 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 MBLJ25X100-100 instead of this discontinued model.
