This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD40X15, 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 MALD40X15
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15 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 MBLD40X15, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15
The AirTAC MALD40X15 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal force both ways at 528 N (0.5 MPa) and 739 N (0.7 MPa). The direct replacement is the MBLD40X15, matching the 40mm bore, 15mm stroke, G1/4 port, and mounting.
This SKU has no magnet (-S) and cannot accept a position sensor. The MALD used threaded covers and fixed rubber bumpers; the MBLD upgrade features a riveted rolling-packed body. Twin rods resist rotation and double the bearing area for guided slide applications.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X15 |
| Bore size | Ø40 mm |
| Stroke | 15 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 MBLD40X15 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 MBLD40X15 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15 Is Used
PCB Edge Deburring
Twin rods provide anti-rotation stability for a deburring blade, applying 528 N of equal force on the forward and return strokes to scrape board edges without twisting.
Stamping Press Feed
Drives a short 15mm gripper stroke to feed thin sheet metal into a stamping die, using the rear rod to push an opposing cam for synchronized timing.
Guided Clamp Slide
Clamps aluminum extrusions in a cutting fixture. The double-rod bearing handles the side-load of the saw, while the fixed rubber bumper softens the 15mm end impact.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15 with MBLD40X15
Replace this MALD40X15 with the MBLD40X15. Confirm the 40mm bore, 15mm stroke, G1/4 PT port, and M12x1.25 rod-end thread. Mount on the body, FA flange, or LB foot; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot hold a sensor; if you need position detection, step up to an MBLD40X15S and switch from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG switches.
Size on the equal force: this 40mm bore delivers 528 N each way at 0.5 MPa. If you need less force, step down to the 32mm bore (346 N); if you need more, 40mm is the largest available in this series.
Upgrade checklist
- ✓ Order the MBLD40X15 (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 MBLD40X15 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15 FAQ
Yes, the MALD40X15 is discontinued. The direct replacement is the MBLD40X15, which matches the 40mm bore, 15mm stroke, G1/4 port, and force. The MBLD upgrades the design with a riveted rolling-packed body instead of threaded covers.
Force is equal both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. This specific SKU has no -S magnet, so it cannot accept a position sensor. The fixed rubber bumper is not a lock; the rod will drift on air loss.
