This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X35-30, 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 MALJ25X35-30

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X35-30
The AirTAC MALJ25X35-30 is a discontinued double-acting, adjustable-stroke mini cylinder. It has a 25mm bore, 35mm stroke, and a 30mm rear adjuster, giving a usable end-position window of 5-35mm. The direct replacement is the MBLJ25X35-30, matching the bore, stroke, force, and G1/8 port.
This SKU lacks a magnet (-S), so it cannot take a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but holds no load without live air. It uses a fixed rubber bumper, not an adjustable cushion. Upgrade facts: the MALJ uses threaded covers and older CS1-M/DS1-M sensors, while the MBLJ uses a riveted rolling-packed body and CMSG/DMSG/EMSG switches.

| Adjustable window | 5 – 35 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |

| 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 MBLJ25X35-30 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 MBLJ25X35-30 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X35-30 Is Used
PCB Edge-Guide Trimming
Dial the rear stop to precisely trim the travel window down to 5mm for delicate PCB edge-guide positioning without re-engineering the machine head.
Small-Part Ejector Stroke
Adjusts the ejection reach on a small-parts conveyor chute, tuning the retract distance to match varying product widths without adding external spacers.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X35-30 with MBLJ25X35-30
To replace this MALJ25X35-30, specify the MBLJ25X35-30 to keep the 25mm bore, 35mm stroke, 30mm adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only (no back cover or SDB). Since this SKU lacks a -S magnet, it cannot accept a sensor; upgrading to an MBLJ with a -S magnet enables CMSG/DMSG/EMSG switches.
The 30mm adjuster sets the end position but is not a load lock; add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ25X35-30 (same bore/stroke/adjust)
- ✓ Same 5–35 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 MBLJ25X35-30 instead of this discontinued model.
