This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD40X75, 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 MALD40X75
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75 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 MBLD40X75, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75
The AirTAC MALD40X75 is a discontinued double-acting, double-rod mini cylinder with a 40 mm bore and 75 mm stroke. Because twin rods exit both ends, the annulus areas match, delivering equal push and pull force of 528 N each way at 0.5 MPa (108 kgf max at 1.0 MPa). The direct replacement is the MBLD40X75, sharing the same bore, stroke, force, G1/4 port, and mounting.
This SKU lacks the -S magnet code, so it cannot accept a position sensor; the MBLD upgrade uses CMSG, DMSG, or EMSG switches on magnetized variants. The legacy MALD uses threaded covers and a fixed rubber bumper, while the modern MBLD features a riveted rolling-packed body. Twin rods double the bearing surface for high side-load resistance and allow mounting a cam or flag on the rear rod.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X75 |
| Bore size | Ø40 mm |
| Stroke | 75 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 MBLD40X75 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 MBLD40X75 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75 Is Used
PCB Router Z-Axis
Twin 16 mm rods resist spindle torque during 75 mm plunge cuts, using the 528 N equal force to lift the 40 mm routing head smoothly without rotational drift.
Bottle Capper Head
Applies 739 N of downward capping force at 0.7 MPa, while the rear rod protrudes to trigger a mechanical flag confirming cap seating without needing a sensor.
Strip Feed Ejector
Ejects metal stampings from a progressive die with equal push and pull, ensuring the dual-bearing 40 mm body returns the tool cleanly even under off-center loads.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75 with MBLD40X75
To replace the MALD40X75 with the MBLD40X75, confirm the 40 mm bore, 75 mm stroke, G1/4 port, M12x1.25 rod-end thread, and PT thread form. Mounting uses FA flange or LB foot on the body; there is no back-cover or SDB option. Because this SKU has no -S magnet, it cannot hold a sensor; upgrading to an -S MBLD moves you from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
Size on the equal 528 N force both ways. If you need less force, step down to the 32 mm bore (346 N @0.5 MPa). If you need more, note 40 mm is the largest MALD size available. The 75 mm stroke is well within the 500 mm maximum, so no side-load guide concerns apply.
Upgrade checklist
- ✓ Order the MBLD40X75 (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 MBLD40X75 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75 FAQ
Yes, the MALD40X75 is discontinued. The direct replacement is the MBLD40X75, which matches the 40 mm bore, 75 mm stroke, G1/4 port, and mounting. The MBLD upgrades the threaded covers to a riveted rolling-packed body.
Force is equal because both rods exit the bore, making the annulus area identical on the push and pull sides. The ratings are 528 N @0.5 MPa, 739 N @0.7 MPa, and a maximum of 108 kgf @1.0 MPa in both directions. This SKU has no -S magnet, so it cannot accept a position sensor.
