This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X20 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 MALD25X20
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20 is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø25mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD25X20, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20
The AirTAC MALD25X20 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 25mm bore, producing equal force both ways at 206 N at 0.5 MPa. The direct drop-in replacement is the MBLD25X20, matching the 20mm stroke, G1/8 port, and mounting.
This SKU has no magnet and cannot take a position sensor. The original MALD uses threaded covers, while the MBLD upgrade features a riveted rolling-packed body. Twin rods resist rotation and double the bearing load, allowing the rear rod to carry a flag or secondary tooling.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X20 |
| Bore size | Ø25 mm |
| Stroke | 20 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 MBLD25X20 carries the same ratings.
Output Force — Equal Both Ways (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | 289 N |
| Max (@1.0 MPa) | 42 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD25X20 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 MALD25X20 Is Used
PCB Shuttle Transfer
Drives a short 20mm stroke shuttle in PCB pick-and-place machines, using the 206N equal force to push and pull wafers without skewing.
Dual-End Tooling Slide
Powers a compact slide where the front rod actuates a cutter and the rear rod mounts a mechanical flag for physical stroke confirmation.
Label Applicator Head
Actuates a label wipe-down head in packaging lines, relying on the twin rods to prevent torsion during rapid 20mm apply strokes.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20 with MBLD25X20
To replace the MALD25X20 with the MBLD25X20, confirm the 25mm bore, 20mm stroke, G1/8 port, and PT thread. This non-magnet SKU cannot accept a sensor; if sensing is needed, step up to an MBLD25X20S and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Mount on the body or via FA/LB, as there is no back cover or SDB option.
Size using the equal force: 206 N each way at 0.5 MPa. If you need less force, step down to the 20mm bore (132 N at 0.5 MPa). If you need more, step up to the 32mm bore (346 N at 0.5 MPa).
Upgrade checklist
- ✓ Order the MBLD25X20 (same bore/stroke/force)
- ✓ Force equal both ways (206 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 MBLD25X20 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20 FAQ
Yes, the MALD25X20 is discontinued. The exact drop-in replacement is the MBLD25X20, matching the 25mm bore, 20mm stroke, G1/8 port, and mounting. The MBLD upgrades the construction to a riveted rolling-packed body.
Push and pull forces are equal: 206 N at 0.5 MPa and 289 N at 0.7 MPa, with a maximum of 42 kgf at 1.0 MPa. It uses a fixed rubber bumper to soften end impacts, but it is not a lock and the rod will drift on air loss.
