This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD20X50, 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 MALD20X50
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50 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 direct replacement is the MBLD20X50, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50
The AirTAC MALD20X50 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal force both ways (132 N each way at 0.5 MPa). The direct replacement is the MBLD20X50.
This 20 mm bore uses a G1/8 port and an 8 mm carbon-steel rod with a hard chrome plating. It features fixed rubber bumpers and threaded covers. This SKU lacks the -S magnet, so it cannot take a position sensor.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X50 |
| Bore size | Ø20 mm |
| Stroke | 50 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 MBLD20X50 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 MBLD20X50 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 MALD20X50 Is Used
PCB Pick & Place
Drives a small vacuum head on a PCB assembly machine. The 132 N equal force and twin rods prevent chassis twist during rapid vertical placement.
Wire Harness Cutter
Actuates a precision wire cutter. The rear rod mounts a cam to trigger a mechanical stripper, timed perfectly with the 50 mm stroke.
Label Applicator
Pivots a label wipe-down arm on a packaging line. The double-rod bearing handles the side load of the offset roller without binding.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50 with MBLD20X50
Replace the MALD20X50 with the MBLD20X50. Confirm the 20 mm bore, 50 mm stroke, G1/8 port, and PT thread. Mounting uses FA or LB only; there is no back cover or SDB. Since this SKU lacks the -S magnet, it cannot accept the CS1-M/DS1-M sensors. The MBLD upgrade uses CMSG/DMSG/EMSG sensors and a riveted body.
Size on the equal force of 132 N at 0.5 MPa. To step up, the 25 mm bore provides 206 N at 0.5 MPa. Being the smallest bore, 20 mm is your only step down.
Upgrade checklist
- ✓ Order the MBLD20X50 (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 MBLD20X50 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50 FAQ
Yes, the MALD20X50 is discontinued. The direct replacement is the MBLD20X50. It matches the 20 mm bore, 50 mm stroke, 132 N equal force, G1/8 port, and FA/LB mounting. The MBLD upgrades to a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Force is equal both ways: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. It uses fixed rubber bumpers for end-of-stroke impact, not adjustable cushions. It cannot hold a load on air loss.
