This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X350-75, 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 MALJ25X350-75
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 275 to 350 mm. This model is discontinued — the direct replacement is the MBLJ25X350-75.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75
The AirTAC MALJ25X350-75 is a discontinued double-acting mini cylinder with a 25 mm bore and a 350 mm stroke. It is a non-standard, made-to-order length because it exceeds the 300 mm standard stroke limit for this bore. The rear screw stopper lets you trim up to 75 mm, creating a usable end-position window of 275-350 mm. The direct replacement is the MBLJ25X350-75, which matches the bore, stroke, adjust code, port, and force.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact, but this is not an adjustable air cushion. Upgrading to the MBLJ changes the sensor family (CS1-M/DS1-M to CMSG/DMSG/EMSG) and swaps the threaded covers for a riveted rolling-packed body.

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 MBLJ25X350-75 carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

| 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 MBLJ25X350-75 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75 Is Used
Adjustable PCB ejectors
Trim the rear stopper by up to 75 mm to tune the extraction depth on automated PCB ejection arms, preventing damage to delicate edge connectors.
Carton flap folders
Use the long 350 mm stroke to reach across wide packaging lines, fine-tuning the folding end position to square carton flaps precisely before taping.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75 with MBLJ25X350-75
To replace this MALJ25X350-75, order the MBLJ25X350-75. Confirm the 25 mm bore, 350 mm non-standard stroke, 75 mm adjust code, G1/8 PT port, and M10x1.25 rod thread. Mounting is Basic, FA, or LB only; there is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot take a sensor. At 350 mm, the rod is highly susceptible to side-load bending; ensure strict load alignment to prevent premature seal failure.
Upgrade checklist
- ✓ Order the MBLJ25X350-75 (same bore/stroke/adjust)
- ✓ Same 275–350 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 MBLJ25X350-75 instead of this discontinued model.
