This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X75 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 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 drop-in 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 exact drop-in 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 exact drop-in 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.
