This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X400 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X400 in place of this model. The MBLD replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400 is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø40mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD40X400, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400
The AirTAC MALD40X400 is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends of the 40mm bore, yielding exactly 528 N of force in both push and pull directions at 0.5 MPa. The direct, drop-in replacement is the MBLD40X400, which matches the 400mm stroke, G1/4 port, and mounting footprint.
This SKU has no magnet (-S) and cannot accept a position sensor. The original MALD uses threaded covers and older CS1-M / DS1-M switches; the MBLD upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. End-of-travel impact is absorbed by a fixed rubber bumper, not an adjustable cushion. Twin carbon-steel rods with 20 um hard chrome resist rotation and double the bearing load, which is critical for preventing rod deflection on long 400mm strokes.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X400 |
| Bore size | Ø40 mm |
| Stroke | 400 mm |
| Acting type | Double acting, double rod |
| 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 |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD40X400 carries the same ratings.
Output Force — Equal Both Ways (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |
| Max (@1.0 MPa) | 108 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD40X400 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400 Is Used
PCB Edge Conveyor Tracking
Drives a dual-sided pin conveyor in a wave soldering machine. The equal 528 N force both ways and anti-rotation twin rods keep the 400mm stroke perfectly aligned without chassis twist.
Textile Loom Takedown Guide
Actuates a takedown reed mechanism on a weaving loom. The rear exiting rod mounts a mechanical flag to trip a limit switch, while the 40mm bore handles high fabric tension.
Bottling Line Divert Gate
Shifts a diverter gate on a rotary glass bottle filler. The twin rods prevent the 400mm stroke from twisting under the heavy side-load of redirected liquid-filled containers.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400 with MBLD40X400
To replace the MALD40X400 with the MBLD40X400, confirm the 40mm bore, 400mm stroke, G1/4 port, M12x1.25 rod-end thread, and FA or LB mounting (there is no back-cover or SDB option). Because this is a non-magnetized SKU, it cannot hold a sensor. Size your system on the equal 528 N force at 0.5 MPa. If you need less force, step down to the 32mm bore neighbor, which provides 346 N at 0.5 MPa. If you need more force, the 40mm is the largest standard MALD size, so you would need to migrate to a larger ISO series. For a 400mm stroke, ensure external guides support the load to prevent side-load wear on the rod bearings.
Upgrade checklist
- ✓ Order the MBLD40X400 (same bore/stroke/force)
- ✓ Force equal both ways (528 N at 0.5 MPa)
- ✓ Twin rods for anti-rotation / rear flag
- ✓ No back cover / SDB — plan a body or 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 Protect both rod ends from side load on long strokes.
- check No back-cover / SDB on double-rod — use body / FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLD40X400 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400 FAQ
Yes, the MALD40X400 is discontinued. The exact drop-in replacement is the MBLD40X400, which matches the 40mm bore, 400mm stroke, 528 N equal force, G1/4 port, and mounting. You will upgrade from threaded covers to a riveted rolling-packed body.
Because a rod exits both ends, the piston sees the same annulus area on both sides, making push and pull force identical. The full set of equal forces is 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. This specific SKU has no -S magnet, so it cannot take a sensor.
