This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X20S 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 MALD20X20S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20S 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 MBLD20X20S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20S
The AirTAC MALD20X20S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal push and pull force of 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X20S, matching the 20 mm bore, 20 mm stroke, G1/8 port, and mounting.
This -S SKU includes a magnet for CS1-M / DS1-M switches; the MBLD upgrade uses CMSG / DMSG / EMSG sensors. The original MALD uses threaded covers, while the MBLD features a riveted rolling-packed body. Twin rods double the bearing area and resist rotation, allowing a rear rod to carry a cam or flag while the front rod performs work.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X20S |
| 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 MBLD20X20S 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 MBLD20X20S 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 MALD20X20S Is Used
PCB Edge Clamping
Clamps printed circuit board edges during routing. The twin rods resist rotational twist, keeping the 132 N grip perfectly square without skewing the panel.
Label Flag Trigger
Drives a mechanical flag on the rear rod to trip a limit switch on a labeling line, while the front rod actuates the feed mechanism with matched 132 N force.
Small Part Ejector
Ejects stamped micro-parts from a die. The double-rod design doubles the bearing load, absorbing side friction on the 20 mm stroke without rod binding.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20S with MBLD20X20S
To replace the MALD20X20S, specify the MBLD20X20S. Confirm the 20 mm bore, 20 mm stroke, M8x1.25 rod-end thread, G1/8 port, and FA or LB mounting. MALD has no back-cover code and no SDB; mount directly on the body. Because this is a -S SKU, you must upgrade your sensors from CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
Size on the equal force: this bore delivers 132 N both ways at 0.5 MPa. As the smallest available bore, the next size up is 25 mm, which raises the equal force to 206 N each way. The fixed rubber bumper softens end impact but provides no load holding on air loss.
Upgrade checklist
- ✓ Order the MBLD20X20S (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 MBLD20X20S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X20S FAQ
Yes, the MALD20X20S is discontinued. The exact drop-in replacement is the MBLD20X20S, which matches the 20 mm bore, 20 mm stroke, G1/8 port, and mounting. You will need to update your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The double-rod design yields equal force both ways: 132 N push and 132 N pull at 0.5 MPa, and 185 N each way at 0.7 MPa. The maximum force is 27 kgf at 1.0 MPa. Operating pressure is 0.1-1.0 MPa, speed is 30-800 mm/s, and it uses a fixed rubber bumper, not an adjustable cushion.
