This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X300-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X300-10 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 MALJ40X300-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-10 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 290 to 300 mm. This model is discontinued — the drop-in replacement is the MBLJ40X300-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-10
The AirTAC MALJ40X300-10 is a discontinued double-acting mini cylinder with a 10 mm rear adjustable stroke stopper. It gives a usable travel window of 290-300 mm. The 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X300-10, matching the force, G1/4 port and mounting.
This SKU has no -S magnet, so it cannot take a position sensor. The adjuster sets the end position but does not hold load without live air. Upgrading to the MBLJ changes the sensor family (if needed) and swaps the MAL threaded covers for a riveted rolling-packed body. Impact is softened only by a fixed rubber bumper.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-10 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-10 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X300-10 |
| Bore size | Ø40 mm |
| Stroke | 300 mm |
| Adjustable window | 290 – 300 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 MBLJ40X300-10 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 MBLJ40X300-10 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-10 Is Used
Printed Circuit Board Conveyor
Dial the 290-300 mm reach to index PCBs on a conveyor line without moving cylinder mounts, using 628 N push to clear product stops.
Long-Stroke Pallet Pusher
Trim the 10 mm end position to align pallets entering a shrink-wrap tunnel, relying on the 528 N pull force to retract the 16 mm rod.
Thermoforming Ejector
Fine-tune the ejection depth of formed plastic parts on a 300 mm stroke, using the fixed rubber bumper to soften the high-speed end impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-10 with MBLJ40X300-10
To replace the MALJ40X300-10, order the MBLJ40X300-10. Confirm the 40 mm bore, 300 mm stroke, 10 mm adjust code, G1/4 port, M12x1.25 rod-end thread and PT thread form. Mounting is FA or LB only; there is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a CS1-M or DS1-M sensor. The MBLJ replacement uses CMSG, DMSG or EMSG switches if you need sensing.
For sizing, stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N. Stepping up to a larger standard bore increases force beyond 880 N. The rear adjuster is a travel stop, not a lock; it cannot hold a load without air. At 300 mm stroke, prevent rod bending by avoiding side loads and guiding the load rigidly.
Upgrade checklist
- ✓ Order the MBLJ40X300-10 (same bore/stroke/adjust)
- ✓ Same 290–300 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 MBLJ40X300-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-10 FAQ
Yes, the MALJ40X300-10 is discontinued. The exact drop-in replacement is the MBLJ40X300-10, which matches the 40 mm bore, 300 mm stroke, 10 mm adjust code, G1/4 port and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG, DMSG or EMSG sensors instead of the older CS1-M or DS1-M switches.
This 40 mm bore cylinder provides 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The 10 mm rear adjuster creates a usable stroke window of 290-300 mm. The adjuster is a travel stop, not a lock; it sets the end position but does not hold the load without live air.
