This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X15 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X15 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 MALD20X15
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15 is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø20mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD20X15, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15
The AirTAC MALD20X15 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering an equal 132 N push and pull force at 0.5 MPa. The exact drop-in replacement is the MBLD20X15, matching the 20 mm bore, 15 mm stroke, G1/8 port and mounting.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The original MALD uses threaded covers and the older CS1-M / DS1-M switches; the MBLD upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. Twin rods double the bearing area and resist rotation, allowing a cam or flag on the rear rod.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X15 |
| Bore size | Ø20 mm |
| Stroke | 15 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 300 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD20X15 carries the same ratings.
Output Force — Equal Both Ways (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | 185 N |
| Max (@1.0 MPa) | 27 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD20X15 matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15 Is Used
PCB Edge Cutter
Drives a synchronized cutting head on an electronic PCB depaneling router, using the 132 N equal force and twin rods to prevent blade yaw.
Connector Insertion Head
Pushes and pulls a dual-pick tool to seat pin headers into plastic blocks, relying on anti-rotation guidance for the 15 mm stroke.
Label Cam Stamp
Mounts a mechanical cam on the rear rod to trigger a glue valve on a packaging line, keeping the front rod dedicated to the stamping task.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15 with MBLD20X15
To replace the MALD20X15 with the MBLD20X15, confirm the 20 mm bore, 15 mm stroke, G1/8 PT port, and M8x1.25 rod-end thread. Because this is a non-magnet SKU, you cannot mount a sensor. Mount directly on the body or via FA/LB, as there is no back cover or SDB option. The fixed rubber bumper softens end impact but provides no load holding on air loss.
Size on the equal 132 N force at 0.5 MPa. To step down, the smallest bore in the family is 20 mm. To step up, the neighbouring 25 mm bore provides 206 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X15 (same bore/stroke/force)
- ✓ Force equal both ways (132 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 MBLD20X15 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15 FAQ
Yes, the MALD20X15 is discontinued. The exact drop-in replacement is the MBLD20X15, which matches the 20 mm bore, 15 mm stroke, G1/8 port and mounting. The MBLD upgrades the body to a riveted rolling-packed design and uses CMSG / DMSG / EMSG sensors instead of the older CS1-M / DS1-M switches.
Because a rod exits both ends, the annulus area is identical on both sides, making push and pull force equal. For this 20 mm bore, the force is 132 N at 0.5 MPa, 185 N at 0.7 MPa, and the maximum force is 27 kgf at 1.0 MPa. This SKU has no -S magnet and cannot take a sensor.
