This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X25 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X25 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 MALD20X25
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25 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 MBLD20X25, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25
The AirTAC MALD20X25 is a discontinued double-acting, double-rod mini cylinder. Because twin rods exit both ends, the annulus area is identical on each side, giving exactly 132 N of force both ways at 0.5 MPa. The direct drop-in replacement is the MBLD20X25, matching the 20 mm bore, 25 mm stroke, G1/8 port and mounting.
This SKU has no -S magnet, so it cannot accept a position sensor; the MBLD upgrade switches to CMSG/DMSG/EMSG switches if sensing is needed. The original MALD uses threaded covers, while the MBLD replacement features a riveted rolling-packed body. Both rely on a fixed rubber bumper, meaning there is no adjustable cushioning.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X25 |
| Bore size | Ø20 mm |
| Stroke | 25 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 MBLD20X25 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 MBLD20X25 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25 Is Used
PCB Depaneling Saw
Feeds a circular saw blade on a PCB depaneling router using 132 N of equal push/pull force, ensuring the blade retracts smoothly without snapping the fragile board edge.
Connector Insertion Jig
Drives a small pick-and-place head to press micro-USB connectors into housings, using the twin rods to prevent tool rotation during the 25 mm insertion stroke.
Label Applicator Wipe
Actuates a wipe-down arm on a bottle labeling station, using the rear rod end to mount a mechanical cam that triggers the next bottle feed in sequence.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25 with MBLD20X25
To replace the MALD20X25, specify the MBLD20X25 and confirm the 20 mm bore, 25 mm stroke, G1/8 port, and PT thread. Mount via the body or FA/LB brackets, as there is no back cover or SDB option. Size using the equal force: this bore gives 132 N each way at 0.5 MPa. If you need less force, there is no smaller bore in this series. If you need more force, step up to the 25 mm bore, which provides 206 N both ways at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X25 (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 MBLD20X25 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25 FAQ
Yes, the MALD20X25 is discontinued. The exact drop-in replacement is the MBLD20X25, which matches the 20 mm bore, 25 mm stroke, G1/8 port, and equal-both-ways force. You will just need to update your sensor choice if used, as the MBLD uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
Because it is a double-rod cylinder, push and pull forces are equal: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. It uses a fixed rubber bumper at the end of stroke for impact absorption; it does not have adjustable cushioning, and it cannot hold a load on air loss.
