This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X400S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X400S 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 MALD40X400S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400S 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 MBLD40X400S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400S
The AirTAC MALD40X400S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering equal push and pull force of 528 N each way at 0.5 MPa. The direct drop-in replacement is the MBLD40X400S, matching the 40 mm bore, 400 mm stroke, G1/4 port, and mounting.
This -S SKU includes a magnet for CS1-M/DS1-M switches; the MBLD upgrade shifts to CMSG/DMSG/EMSG sensors. The MALD uses threaded covers, while the MBLD features a riveted rolling-packed body. With a 400 mm stroke, the twin rods provide critical anti-rotation guidance and double the bearing area to handle rod sag, which a single rod cannot match. End-of-travel impact relies on a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X400S |
| 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 MBLD40X400S 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 MBLD40X400S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400S Is Used
PCB Edge-Routing Z-Axis
Drives a router spindle up and down on a printed circuit board panel. The twin rods prevent spindle rotation during plunge cuts, while the 528 N equal force ensures consistent depth on both the extend and retract strokes.
Textile Beam Loom Feed
Actuates a tensioning gate on a weaving loom. The 400 mm stroke accommodates wide beam traversal, and the rear rod end mounts a mechanical flag to trigger a physical limit switch for redundant material feed monitoring.
Dual-Side Carton Flap Folder
Pushes opposing cardboard flaps simultaneously from both ends of a packaging line. The double-rod body carries the folding blade on one end and a cam on the rear, timing the fold without requiring a separate cylinder.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400S with MBLD40X400S
To replace the MALD40X400S with the MBLD40X400S, confirm the 40 mm bore, 400 mm stroke, G1/4 port, and M12x1.25 rod-end thread. Mounting remains FA flange or LB foot, as double-rod cylinders have no back cover and do not accept SDB. The -S magnet requires switching from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. Size on the equal 528 N force; if you need less power, step down to the 32 mm bore (346 N at 0.5 MPa). If you need more, 40 mm is the largest MALD bore. At 400 mm stroke, ensure external guides support side loads to prevent binding.
Upgrade checklist
- ✓ Order the MBLD40X400S (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 MBLD40X400S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400S FAQ
Yes, the MALD40X400S is discontinued. The exact drop-in replacement is the MBLD40X400S, which matches the 40 mm bore, 400 mm stroke, G1/4 port, and 528 N equal force. You will need to update your sensor brackets, as the MALD -S magnet uses CS1-M/DS1-M switches, while the MBLD uses CMSG/DMSG/EMSG switches.
The double-rod design yields equal force both ways: 528 N push and 528 N pull at 0.5 MPa, and 739 N each way at 0.7 MPa. The maximum force is 108 kgf at 1.0 MPa. It uses a fixed rubber bumper at the stroke ends; there is no adjustable cushion on this MALD model.
