This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X25-10SLB, 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 MALJ25X25-10SLB

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-10SLB
The AirTAC MALJ25X25-10SLB is a discontinued double-acting mini cylinder with a 25mm bore, 25mm stroke, and a 10mm rear adjuster. This yields a usable end-position window of 15-25mm. The direct replacement is the MBLJ25X25-10SLB, matching the bore, stroke, adjust code, LB foot mount, and G1/8 port.
This -S magnet SKU uses older CS1-M/DS1-M switches, while the MBLJ upgrade moves to CMSG/DMSG/EMSG sensors. The MALJ features threaded covers, whereas the MBLJ uses a riveted rolling-packed body. The rear adjuster acts as a travel stop to fine-tune reach without external stops, but it is not a lock and will not hold a load without live air. End impact is softened by a fixed rubber bumper; there is no adjustable air cushion.

| Bore size | Ø25 mm |
| Stroke | 25 mm |
| Adjustable window | 15 – 25 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |

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 MBLJ25X25-10SLB 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 MBLJ25X25-10SLB matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-10SLB Is Used
Connector Pin Insertion
Fine-tune the downward end position when pressing delicate header pins into molded plastic housings, preventing over-travel damage on the 25mm stroke.
Tube Cutting Clamp
Adjust the rear stop to clamp varying aluminum tube lengths securely in a cutoff saw jig, relying on the LB foot mount for stable base fixing.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-10SLB with MBLJ25X25-10SLB
To replace the MALJ25X25-10SLB, install the direct replacement MBLJ25X25-10SLB. Confirm the 25mm bore, 25mm stroke, 10mm adjust code, LB foot mount, PT G1/8 port, and M10x1.25 rod thread. Remember the adjuster is a stop, not a lock. The -S magnet requires a sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. No back cover or SDB is used.
Upgrade checklist
- ✓ Order the MBLJ25X25-10SLB (same bore/stroke/adjust)
- ✓ Same 15–25 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 MBLJ25X25-10SLB instead of this discontinued model.
