This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD40X15S, 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 MALD40X15S
The AirTAC MALD Aluminum Alloy Mini Cylinder MALD40X15S 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 MBLD40X15S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15S
The AirTAC MALD40X15S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal force both ways at 528 N each way at 0.5 MPa. The direct replacement is the MBLD40X15S, matching the 40mm bore, 15mm stroke, G1/4 port, and mounting.
This SKU includes the -S magnet, which uses the older CS1-M / DS1-M switches. The MBLD upgrade uses CMSG / DMSG / EMSG sensors. The MALD has threaded covers, whereas the MBLD features a riveted rolling-packed body. It uses a fixed rubber bumper, not an adjustable cushion, and mounts via FA or LB without a back cover or SDB.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X15S |
| 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 MBLD40X15S 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 MBLD40X15S 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 MALD40X15S Is Used
PCB Edge Conveyors
Provides 528 N of equal thrust for smooth PCB transfer slides, using the twin rods to prevent chassis twist during rapid indexing.
Injection Mold Ejection
Drives a rear-mounted mechanical ejector pin on molding machines, using the short 15mm stroke for high-cycle part release.
Bottle Diverters
Powers a dual-ended diverter arm on packaging lines, balancing 739 N at 0.7 MPa on both ends to avoid guide binding.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15S with MBLD40X15S
To replace the MALD40X15S with MBLD40X15S, confirm the 40mm bore, 15mm stroke, PT G1/4 port, M12x1.25 rod-end thread, and FA/LB mounting. You must also change your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG. Size strictly on the equal 528 N force at 0.5 MPa. If you need less force, step down to the 32mm bore (346 N at 0.5 MPa); as the largest MALD bore, 40mm is the maximum size available.
Upgrade checklist
- ✓ Order the MBLD40X15S (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 MBLD40X15S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X15S FAQ
Yes, the MALD40X15S is discontinued. The direct replacement is the MBLD40X15S, which matches the 40mm bore, 15mm stroke, 528 N force, and G1/4 port. You will need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
Because a rod exits both ends, the annulus area is identical on both sides, generating equal push and pull force. The figures are 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
