This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X350-10, 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 MALJ25X350-10
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X350-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 340 to 350 mm. This model is discontinued — the direct replacement is the MBLJ25X350-10.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-10
The AirTAC MALJ25X350-10 is a discontinued double-acting mini cylinder with a 10 mm rear stroke adjuster. It provides a usable travel window of 340-350 mm. Because the 350 mm stroke exceeds the 300 mm standard cap for this 25 mm bore, this SKU is a non-standard, made-to-order part. The direct replacement is the MBLJ25X350-10, matching the bore, force, G1/8 port, and adjust code.
It uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster is a travel stop that sets the end position but will not hold a load without live air. This no-magnet SKU cannot take a position sensor. Upgrading to the MBLJ replaces the threaded covers with a riveted rolling-packed body.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-10 Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-10 |

| Replacement | MBLJ25X350-10 |
| Bore size | Ø25 mm |
| Stroke | 350 mm |
| Adjustable window | 340 – 350 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 |
| Proof pressure | 1.5 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 MBLJ25X350-10 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 MBLJ25X350-10 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-10 Is Used
Thin-Wall Tube Extrusion
Acts as a rear depth stop for a 350 mm long extrusion puller, letting operators fine-tune the cut-off point without shimming external hard stops.
Automated Drawer Assembly
Extends a slide-rail jig to its 350 mm limit, using the 10 mm adjuster to compensate for drawer length variances without swapping the cylinder.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-10 with MBLJ25X350-10
To replace this MALJ25X350-10, order the MBLJ25X350-10. Confirm the 25 mm bore, 350 mm stroke, 10 mm adjust code, G1/8 PT port, and FA or LB mounting (no back cover or SDB is used). Because this is a no-magnet SKU, it cannot take a sensor; if you need sensing on the new MBLJ, add the -S code for CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster is a stop, not a lock.
At 350 mm, the 10 mm rod is highly susceptible to side-load bending; keep the load strictly axial or use an external guide to prevent rod failure.
Upgrade checklist
- ✓ Order the MBLJ25X350-10 (same bore/stroke/adjust)
- ✓ Same 340–350 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 MBLJ25X350-10 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-10 FAQ
Yes, the MALJ25X350-10 is discontinued. The direct replacement is the MBLJ25X350-10, which keeps the same 25 mm bore, 350 mm stroke, 10 mm adjust code, and G1/8 port. The MBLJ upgrades the construction to a riveted rolling-packed body from the original threaded covers.
At 0.5 MPa it pushes 245 N and pulls 206 N; at 0.7 MPa it pushes 343 N, with a maximum 50 kgf at 1.0 MPa. The -10 code provides a 340-350 mm usable window. The rear screw is a travel stop that sets the end position; it does not lock the load without air pressure.
