This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X350-50, 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 MALJ25X350-50

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-50
The AirTAC MALJ25X350-50 is a discontinued double-acting double-rod cylinder with a 50 mm rear adjuster, yielding a usable 300-350 mm stroke window. The direct replacement is the MBLJ25X350-50.
This non-standard 350 mm stroke exceeds the 300 mm max standard, making it a made-to-order item. It uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster is a travel stop, not a lock. This SKU lacks a magnet and cannot take a sensor. The original threaded covers upgrade to a riveted body on the MBLJ.

| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-50 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X350-50 |
| Bore size | Ø25 mm |
| Stroke | 350 mm |
| Adjustable window | 300 – 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 MBLJ25X350-50 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 MBLJ25X350-50 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-50 Is Used
PCB Conveyor Gate
Fine-tune the opening depth on a printed circuit board conveyor line, using the rear stop to prevent the 350 mm rod from over-traveling into the frame.
Carton Flap Folder
Adjust the end position on a packaging line to fold varying carton heights, relying on the fixed rubber bumper to soften the 0.7 MPa impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-50 with MBLJ25X350-50
Replace this with the MBLJ25X350-50, confirming the G1/8 port, M10x1.25 rod, and 50 mm adjust code. Mounting is FA or LB only with no back cover. The 350 mm stroke is non-standard; on long strokes, minimize side-load to prevent rod bending. The adjuster sets end position but will not hold a load without live air.
Upgrade checklist
- ✓ Order the MBLJ25X350-50 (same bore/stroke/adjust)
- ✓ Same 300–350 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 MBLJ25X350-50 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-50 FAQ
Yes, the MALJ25X350-50 is discontinued. The direct replacement is the MBLJ25X350-50, matching the 25 mm bore, 350 mm stroke, 50 mm adjust code, and G1/8 port. The MBLJ upgrades the threaded covers to a riveted rolling-packed body.
The 50 mm adjuster lets you trim the end position, creating a 300-350 mm usable window. It acts only as a travel stop and does not lock the load without air pressure.
