This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X20 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 MALD20X20
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20 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 MBLD20X20, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20
The AirTAC MALD20X20 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering equal push and pull force of 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X20, matching the 20 mm bore, 20 mm stroke, G1/8 port, and mounting.
This twin-rod layout resists rotation and doubles the bearing load for precise sliding. Unlike the threaded covers on this MALD, the MBLD20X20 upgrade uses a riveted rolling-packed body. This SKU has no magnet (-S omitted), so it cannot accept a CS1-M or DS1-M position sensor.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X20 |
| Bore size | Ø20 mm |
| Stroke | 20 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 MBLD20X20 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 MBLD20X20 matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |

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 MALD20X20 Is Used
PCB Depaneling Saw
Drives a circular blade on a twin-rod slide. The 132 N equal force both ways holds the cut precisely, while the anti-rotation twin rods keep the 20 mm stroke blade tracking true.
Label Applicator Wipe
Mounts a foam wipe pad on the rear rod to press labels. The second rod acts as a stable guide, preventing yaw during the fast 20 mm travel.
Indexing Pallet Stop
Acts as a hard stop for small pallets on a conveyor line. The fixed rubber bumper absorbs the 132 N end-impact without requiring an external shock absorber.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20 with MBLD20X20
Replace the MALD20X20 directly with the MBLD20X20, confirming the 20 mm bore, 20 mm stroke, PT G1/8 port, M8x1.25 rod-end thread, and FA or LB mounting (there is no back-cover or SDB option). Size your circuit on the 132 N equal force both ways. If you need less force, step down does not exist as 20 mm is the smallest bore. To step up, the next size is 25 mm, which provides 206 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X20 (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 MBLD20X20 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20 FAQ
Yes, the MALD20X20 is discontinued. The exact drop-in replacement is the MBLD20X20, which matches the 20 mm bore, 20 mm stroke, G1/8 port, and equal both-ways force.
Force is equal because a rod exits both ends, making the effective piston area identical on the extend and retract sides. The push and pull force are both 132 N at 0.5 MPa, 185 N at 0.7 MPa, with a maximum of 27 kgf at 1.0 MPa.
