This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X60-40, 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 MALJ25X60-40
The AirTAC MALJ25X60-40 is a discontinued double-acting, double-rod mini cylinder featuring a rear adjustable stroke stopper. It has a 25mm bore, 60mm stroke, and a 40mm adjuster, creating a usable end-position window of 20-60mm. The direct replacement is the MBLJ25X60-40, matching the bore, stroke, force, and G1/8 port.
This SKU has no magnet (-S), so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure. Unlike the current MBLJ with its riveted rolling-packed body, the MALJ uses threaded covers. Impact at the end of travel is softened by a fixed rubber bumper, meaning there is no adjustable air cushion.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-40 Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-40 |

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X60-40 |
| Bore size | Ø25 mm |
| Stroke | 60 mm |
| Adjustable window | 20 – 60 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |

| 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 MBLJ25X60-40 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 MBLJ25X60-40 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-40 Is Used
Dispensing Valve Taper
Adjusts the rear stop to fine-tune the 60mm stroke window, ensuring a pneumatic glue valve tapers off the exact bead size at the end of its travel on an automotive gasket line.
Wire Crimp Tooling Depth
Trims up to 40mm off the standard stroke to set the precise bottoming depth for a terminal crimp press, relying on the fixed rubber bumper to soften the final impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-40 with MBLJ25X60-40
To replace the MALJ25X60-40, order the MBLJ25X60-40. Confirm the 25mm bore, 60mm stroke, 40mm adjust code, G1/8 port, PT threads, and FA/LB mounting (there is no back-cover or SDB option). Because this SKU lacks the -S magnet, it cannot take a sensor; if you need sensing, the MBLJ upgrade uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ25X60-40 (same bore/stroke/adjust)
- ✓ Same 20–60 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 MBLJ25X60-40 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-40 FAQ
Yes, the MALJ25X60-40 is discontinued. The direct replacement is the MBLJ25X60-40, which matches the 25mm bore, 60mm stroke, 40mm adjuster, G1/8 port, and FA/LB mounting. The MBLJ upgrades the construction to a riveted rolling-packed body, but the force and pressure ratings remain the same.
The 40mm adjust code lets you trim the rear travel stop, creating a usable stroke window from 20mm up to 60mm. The adjuster is a travel stop only; it does not hold the load without live air pressure.
