This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X80-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X80-S 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 MALD20X80-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X80-S 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 MBLD20X80-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X80-S
The AirTAC MALD20X80-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 20mm bore, yielding equal push and pull force of 132N each way at 0.5MPa. The exact drop-in replacement is the MBLD20X80-S, matching the 80mm stroke, G1/8 port, and M8 rod-end thread.
This -S SKU includes a magnet for legacy CS1-M or DS1-M reed switches; the MBLD upgrade shifts to CMSG/DMSG/EMSG solid-state sensors. The original MALD uses threaded covers, while the MBLD features a riveted rolling-packed body. Twin rods double the bearing load and prevent rod rotation, allowing a rear-mounted flag or cam. Fixed rubber bumpers absorb end impact, but provide no load holding on air loss.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X80-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X80-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X80-S |
| Bore size | Ø20 mm |
| Stroke | 80 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 MBLD20X80-S 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 MBLD20X80-S 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 MALD20X80-S Is Used
PCB Shuttle Transfer
Drives a dual-sided pick-and-place shuttle in PCB assembly. The twin rods prevent chassis rotation during the 80mm transfer, while the rear rod trips a legacy CS1-M sensor to confirm cycle completion.
Label Feed Splicer
Feeds a label web in a continuous splicing jig. The equal 132N force both ways ensures identical tension on the advance and retract, preventing web slip on the 20mm bore.
Micro-Drill Indexer
Positions a micro-drill head in a jewelry machining station. The fixed rubber bumper softens the tooling impact, while the double-rod geometry resists drill side-torque.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X80-S with MBLD20X80-S
To replace the MALD20X80-S, specify the MBLD20X80-S to retain the 20mm bore, 80mm stroke, G1/8 port, and M8x1.25 rod thread. Mounting uses FA or LB only, as the double-rod design has no back cover or SDB option. The -S magnet requires updating your sensor stock from CS1-M/DS1-M to CMSG/DMSG/EMSG. Size your valves based on the equal 132N force at 0.5MPa. If you need less force, step down to the 16mm bore (confirm its force from the datasheet); if you need more, step up to the 25mm bore, which provides 206N at 0.5MPa.
Upgrade checklist
- ✓ Order the MBLD20X80-S (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 MBLD20X80-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X80-S FAQ
Yes, the MALD20X80-S is discontinued. The exact drop-in replacement is the MBLD20X80-S, matching the 20mm bore, 80mm stroke, G1/8 port, and M8 rod. You must update sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
Force is equal because both rod sides have the same annulus area. The ratings are: push 132N and pull 132N at 0.5MPa, push 185N and pull 185N at 0.7MPa, with a maximum of 27kgf at 1.0MPa.
