This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X150 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X150 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 MALD40X150
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150 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 MBLD40X150, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150
The AirTAC MALD40X150 is a discontinued double-acting, double-rod mini cylinder delivering 528 N of equal push and pull force at 0.5 MPa. Because the rod exits both ends, the annulus area is identical on both sides, making push and pull forces perfectly symmetrical. The drop-in replacement is the MBLD40X150, which matches the 40 mm bore, 150 mm stroke, G1/4 port, and mounting footprint.
This SKU has no magnet (-S) and cannot accept a position sensor. The original MALD used threaded covers and CS1-M/DS1-M switches, while the current MBLD upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. The fixed rubber bumper absorbs end-of-stroke impact, and the twin carbon-steel rods double the bearing load while preventing rotation.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X150 |
| Bore size | Ø40 mm |
| Stroke | 150 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 MBLD40X150 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 MBLD40X150 matches these values.

Replacement: MALD → MBLD. No back-cover (CA/U/CM) and no SDB on double-rod. Mounting: LB / FA.
Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150 Is Used
PCB Edge-Routing Spindle
Drives a routing spindle on a PCB depaneling machine. The twin rods prevent rotational drift during high-speed cuts, while the 528 N equal force ensures clean, balanced entry and exit from the panel.
Bottle Capping Head
Lifts and lowers a capping head on a rotary bottling line. The symmetrical 739 N force at 0.7 MPa applies consistent torque without bias, and the rear rod allows a mechanical flag to trigger a cam.
Glass Vacuum Lifter
Transfers a vacuum cup on a glass-handling slide. The double-rod design resists the heavy side-load of the glass sheet, and the fixed rubber bumper softens the 150 mm travel stop without bounce.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150 with MBLD40X150
To replace the MALD40X150 with the MBLD40X150, confirm the 40 mm bore, 150 mm stroke, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). Since this SKU lacks the -S magnet, you cannot mount a sensor; if sensing is needed, specify an MBLD40X150S and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Size strictly on the 528 N equal force at 0.5 MPa. To step down, the 32 mm bore provides 346 N; to step up, the 40 mm is the largest available, so you must dual-rig cylinders to exceed 528 N.
Upgrade checklist
- ✓ Order the MBLD40X150 (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 MBLD40X150 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150 FAQ
Yes, the MALD40X150 is discontinued. The exact drop-in replacement is the MBLD40X150, which matches the 40 mm bore, 150 mm stroke, G1/4 port, and mounting. The MBLD upgrades the threaded covers to a riveted rolling-packed body.
The push and pull forces are equal: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke impact absorption (not an adjustable cushion or a load-holding lock). This SKU has no -S magnet, so it cannot accept a position sensor.
