This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X280S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X280S 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 MALD20X280S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X280S 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 MBLD20X280S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X280S
The AirTAC MALD20X280S 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 MBLD20X280S, matching the 20 mm bore, 280 mm stroke, G1/8 port, and mounting.
This MALD features a -S magnet for older CS1-M / DS1-M switches, whereas the MBLD upgrades to CMSG / DMSG / EMSG sensors. The original uses threaded covers, while the replacement uses a riveted rolling-packed body. The twin rods resist rotation and double the bearing load for guided sliding, and the rear rod can carry a flag or cam. A fixed rubber bumper absorbs end impact.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X280S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X280S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X280S |
| Bore size | Ø20 mm |
| Stroke | 280 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 MBLD20X280S 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 MBLD20X280S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X280S

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 MALD20X280S Is Used
PCB Pick-and-Place
Drives a dual-vacuum head across a 280 mm stroke. The twin rods prevent beam rotation during rapid vertical placement of electronic components on the production line.
Textile Loom Guide
Shifts a yarn guide back and forth. The equal 132 N force both ways ensures consistent tensioning without the force drop seen in single-rod units.
Rear Cam Trip Switch
The rear extension rod carries a cam that physically trips a limit switch at the end of travel, providing a hard mechanical signal independent of the -S magnet.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X280S with MBLD20X280S
To replace the MALD20X280S, specify the MBLD20X280S and confirm the 20 mm bore, 280 mm stroke, M8x1.25 rod-end thread, PT G1/8 port, and FA or LB mounting. Retain the -S magnet but swap CS1-M / DS1-M switches for CMSG / DMSG / EMSG units. There is no back-cover or SDB option on this body.
Size on the equal 132 N force. If you need less power, step down to the 20 mm bore's nearest neighbour, but note 20 is the smallest size. To step up, the 25 mm bore provides 206 N at 0.5 MPa. At 280 mm stroke, ensure external guide shafts support side-load to prevent bearing wear.
Upgrade checklist
- ✓ Order the MBLD20X280S (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 MBLD20X280S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X280S FAQ
Yes, the MALD20X280S is discontinued. The exact drop-in replacement is the MBLD20X280S, matching the 20 mm bore, 280 mm stroke, G1/8 port, and mounting. You must change the sensor family: the old -S magnet used CS1-M / DS1-M switches, while the MBLD requires CMSG / DMSG / EMSG switches.
The force is equal both ways because a rod exits both ends, making the annulus area identical on the push and pull sides. The ratings are 132 N @0.5 MPa, 185 N @0.7 MPa, and a maximum of 27 kgf @1.0 MPa for both directions. It uses a fixed rubber bumper, not an adjustable cushion.
