This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X350-100, 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 MALJ25X350-100
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X350-100 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 250 to 350 mm. This model is discontinued — the direct replacement is the MBLJ25X350-100.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-100
The AirTAC MALJ25X350-100 is a discontinued double-acting mini cylinder with a rear adjustable stroke stopper. It trims up to 100 mm at the rear, yielding a usable 250-350 mm end-position window. The direct replacement is the MBLJ25X350-100.
This non-standard 350 mm stroke unit exceeds the 300 mm standard cap, making it a made-to-order item. It lacks a magnet, so it cannot take a position sensor. The rear adjuster sets travel but is a stop, not a lock—it will not hold a load without live air. The original uses a fixed rubber bumper and threaded covers; the MBLJ upgrade shifts to a riveted rolling-packed body.

| Stroke | 350 mm |
| Adjustable window | 250 – 350 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| 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 MBLJ25X350-100 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 MBLJ25X350-100 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-100 Is Used
PCB Depanelling Press
Dials the 250-350 mm reach to shear specific board widths.
Textile Loom Tensioner
Trims the 350 mm stroke window to maintain exact fabric take-up. The long travel accommodates large fabric rolls, while the fixed bumper absorbs the end impact.
Carton Flap Folder
Adjusts the end position for varying box depths on a packaging line. The rear stopper allows quick 100 mm reach changes without swapping cylinders or adding external hardware.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-100 with MBLJ25X350-100
To replace this MALJ25X350-100, order the MBLJ25X350-100. Confirm the 25 mm bore, 350 mm stroke, 100 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Because this SKU has no -S magnet, it cannot accept a sensor; if you need sensing, the MBLJ-S uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster is a travel stop, not a lock.
At 350 mm, the 10 mm rod is highly vulnerable to side-load bending; ensure rigid guidance to prevent premature seal failure.
Upgrade checklist
- ✓ Order the MBLJ25X350-100 (same bore/stroke/adjust)
- ✓ Same 250–350 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 MBLJ25X350-100 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-100 FAQ
Yes, the MALJ25X350-100 is discontinued. The direct replacement is the MBLJ25X350-100, matching the 25 mm bore, 350 mm stroke, 100 mm adjust code, G1/8 port, and force. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The 100 mm adjuster is a travel stop that lets you trim the end position, creating a usable 250-350 mm window. It does not hold the load without live air.
