This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X350-75-S, 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 MALJ25X350-75-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 275 to 350 mm. This model is discontinued — the direct replacement is the MBLJ25X350-75-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75-S
The AirTAC MALJ25X350-75-S is a discontinued double-acting double-rod mini cylinder with a 25mm bore and 350mm stroke. The 75mm rear adjuster yields a usable 275-350mm end-position window. The direct replacement is the MBLJ25X350-75-S.
This non-standard 350mm stroke exceeds the 300mm standard max, making it a special-order item. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. The fixed rubber bumper softens impact. The MALJ uses threaded covers and a CS1-M/DS1-M magnet, whereas the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75-S Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75-S |

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X350-75-S |
| Bore size | Ø25 mm |
| Stroke | 350 mm |
| Adjustable window | 275 – 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 MBLJ25X350-75-S 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 MBLJ25X350-75-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75-S Is Used
Long-Reach Lever Actuators
Drives extended packaging flap folders needing a 275-350mm reach.
Adjustable Depth Stops
Sets variable insertion depth on PCB test fixtures. The 75mm rear adjustment window allows operators to tune the 350mm travel without machining new physical hardstops.
Long-Stroke Ejector Arms
Ejects formed parts from deep molds. The 206N pull force safely retracts the 10mm rod across the 350mm span, while the bumper absorbs the end-of-stroke impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75-S with MBLJ25X350-75-S
To replace this MALJ25X350-75-S, order the exact direct replacement MBLJ25X350-75-S. Confirm the 25mm bore, 350mm stroke, 75mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the adjuster is a stop, not a lock.
Because this 350mm stroke is non-standard and exceeds 300mm, the extended 10mm rod is highly susceptible to bending under side loads; use rigid guidance to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ25X350-75-S (same bore/stroke/adjust)
- ✓ Same 275–350 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 MBLJ25X350-75-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X350-75-S FAQ
Yes, the MALJ25X350-75-S is discontinued. The direct replacement is the MBLJ25X350-75-S, matching the 25mm bore, 350mm stroke, 75mm adjuster, G1/8 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design and changes the -S magnet sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 350mm stroke exceeds the 300mm standard maximum for this bore, making it a non-standard, made-to-order length. The 75mm adjuster allows a usable stroke window of 275-350mm.
