This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD40X80, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALD40X80
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80 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 direct replacement is the MBLD40X80, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80
The AirTAC MALD40X80 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 40mm bore, yielding equal push and pull force of 528N at 0.5MPa and 739N at 0.7MPa. The direct replacement is the MBLD40X80, matching the 80mm stroke, G1/4 port, and mounting.
This SKU has no -S magnet and cannot take a position sensor; the MBLD upgrade with a -S code uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The MALD uses threaded covers, while the MBLD features a riveted rolling-packed body. Twin rods double the bearing surface and resist rotation, letting you mount a cam or flag on the rear rod while absorbing side loads without a separate guide.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X80 |
| Bore size | Ø40 mm |
| Stroke | 80 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 MBLD40X80 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 MBLD40X80 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80 Is Used
PCB Depaneling Saw
Drives a circular blade on a guided slide. The twin rods prevent rotational yaw during the 80mm cut, while the 528N force at 0.5MPa cleanly pushes the fixture against the router fence.
Textile Beam Loom
Actuates a thread tensioning cam from the rear rod. Equal 739N force at 0.7MPa on the return stroke guarantees consistent tension without requiring a heavier single-rod cylinder.
Bottle Capper Head
Lifts and lowers a capping chuck. The fixed rubber bumper softens the 80mm stroke end-impact to protect glass bottles, while the double-rod design keeps the chuck perfectly aligned.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80 with MBLD40X80
To replace the MALD40X80, specify the MBLD40X80 with the same 40mm bore, 80mm stroke, G1/4 port, and PT thread. Mount on the body, or use FA flange or LB foot brackets—there is no back-cover or SDB option. Size your valves based on the equal 528N force at 0.5MPa. If you need less force, step down to the 32mm bore (346N at 0.5MPa); if you need more, the 40mm bore is the largest available in this series (108kgf max at 1.0MPa).
Upgrade checklist
- ✓ Order the MBLD40X80 (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 MBLD40X80 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80 FAQ
Yes, the MALD40X80 is discontinued. The direct replacement is the MBLD40X80, which matches the 40mm bore, 80mm stroke, G1/4 port, and equal 528N force. The MBLD upgrades the construction to a riveted rolling-packed body instead of threaded covers.
The MALD40X80 is double-acting with equal force both ways: 528N at 0.5MPa, 739N at 0.7MPa, and a maximum of 108kgf at 1.0MPa. This specific SKU has no -S magnet and cannot take a position sensor. If you need sensing, the MBLD40X80S replacement uses CMSG/DMSG/EMSG switches.
