This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X30-30, 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).

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-30
The AirTAC MALJ25X30-30 is a discontinued adjustable-stroke mini cylinder. The 30 mm adjuster trims the rear position, creating a usable stroke window of 0-30 mm. The direct replacement is the MBLJ25X30-30, matching the bore, force, G1/8 port, and mounting.
This SKU has no magnet (-S), so it cannot accept a position sensor. The rear screw is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses threaded covers and fixed rubber bumpers, while the MBLJ upgrade features 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 MBLJ25X30-30 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 MBLJ25X30-30 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-30 Is Used
PCB Router Depth Stop
Dial the end position to 15 mm to plunge a PCB depaneling router bit precisely without piercing the vacuum fixture.
Wire Form Bender
Trims the stroke window to 10 mm to consistently bend 2 mm steel wire into J-clips on a high-speed forming machine.
Carton Flap Tucker
Adjusts the rear stop to 25 mm to tuck minor flaps on varying box heights without repositioning the cylinder block.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-30 with MBLJ25X30-30
Replace this MALJ25X30-30 directly with the MBLJ25X30-30. Confirm the 25 mm bore, 30 mm base stroke, 30 mm adjust code, PT G1/8 port, and FA/LB mounting (no back cover or SDB). Because this SKU lacks the -S magnet, it cannot take a sensor; upgrading to an MBLJ-S model enables the newer CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ25X30-30 (same bore/stroke/adjust)
- ✓ Same 0–30 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 MBLJ25X30-30 instead of this discontinued model.
