This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X50-10-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X50-10-S in place of this model. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10-S 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 40 to 50 mm. This model is discontinued — the drop-in replacement is the MBLJ40X50-10-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10-S
The AirTAC MALJ40X50-10-S is a discontinued double-acting mini cylinder with a 40mm bore, 50mm stroke, and 10mm rear adjuster. It provides a usable end-position window of 40-50mm. The bore yields 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X50-10-S, matching the bore, stroke, force, and G1/4 port.
The 10mm adjuster is a travel stop, not a lock; it cannot hold a load without live air. This MALJ features threaded covers and a -S magnet for CS1-M/DS1-M switches. The MBLJ upgrade uses a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. It has a fixed rubber bumper, not an adjustable cushion, and uses FA/LB mounting with no back cover or SDB.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X50-10-S |
| Bore size | Ø40 mm |
| Stroke | 50 mm |
| Adjustable window | 40 – 50 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 500 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 MBLJ40X50-10-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X50-10-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10-S Is Used
Thermoforming Press Depth
Dial the 40-50mm window to set precise mold contact on a 628N press, avoiding frame redesign when plastic sheet thickness varies.
PCB Edge Connector Seating
Trim the 10mm stop to softly seat connectors with the fixed rubber bumper, preventing damage to delicate pin arrays.
Tube End Flaring Stop
Lock the rear screw to set exact pipe insertion depth, using the 528N pull force to withdraw the rod reliably after flaring.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10-S with MBLJ40X50-10-S
To replace the MALJ40X50-10-S with the MBLJ40X50-10-S, confirm the 40mm bore, 50mm stroke, 10mm adjust code, G1/4 port, and PT thread. Verify your FA or LB mounting (no back cover/SDB allowed). The -S magnet means your old CS1-M/DS1-M switches must change to CMSG/DMSG/EMSG on the MBLJ. Remember the rear adjuster is a travel stop, not a lock.
For sizing, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to the largest 40mm bore caps the range at 628N push. If your stroke needs exceed 500mm, note that long strokes increase rod-bending side-load risks; use guide rails to prevent jamming.
Upgrade checklist
- ✓ Order the MBLJ40X50-10-S (same bore/stroke/adjust)
- ✓ Same 40–50 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 MBLJ40X50-10-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X50-10-S FAQ
Yes, the MALJ40X50-10-S is discontinued. The exact drop-in replacement is the MBLJ40X50-10-S, which matches the 40mm bore, 50mm stroke, 10mm adjuster, G1/4 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The -10 adjust code gives a usable stroke window of 40-50mm. The adjuster is a travel stop, not a lock, and this model uses a fixed rubber bumper, not an adjustable cushion.
