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

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25-S
The AirTAC MALD20X25-S double-acting double-rod cylinder is discontinued. The exact drop-in replacement is the MBLD20X25-S, matching the 20mm bore, 25mm stroke, G1/8 port and mounting. This mini cylinder outputs 132 N each way at 0.5 MPa.
Because a rod exits both ends, the annulus area is identical on extension and retraction, giving perfectly equal push and pull force. The twin rods double the bearing load and prevent rotation, letting you mount a flag or cam on the rear rod. This older MALD uses threaded covers and a CS1-M/DS1-M magnet switch, while the MBLD upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X25-S |
| 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-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 MBLD20X25-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25-S

| S | Optional magnet for a CS1-M / DS1-M sensor (MBLD uses CMSG/DMSG/EMSG). |
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 MALD20X25-S Is Used
PCB Pick-and-Place
Drives a vacuum gripper for electronic board assembly, using the twin rods to prevent chuck rotation during rapid 25mm vertical placement moves.
Label Applicator
Powers a labeling head where the rear rod carries a cam to trigger a glue valve, relying on the 132N equal force for consistent retraction.
Small Part Ejector
Ejects plastic parts from an injection mold, using the fixed rubber bumper to soften end-of-stroke impact without needing adjustable cushioning.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25-S with MBLD20X25-S
To replace this MALD20X25-S with the MBLD20X25-S, confirm the 25mm stroke, G1/8 port, M8x1.25 rod thread and FA/LB mounting. Note that the double-rod design uses no back cover or SDB code, mounting directly on the body. The -S magnet requires changing your CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family. Size your application on the equal 132 N force at 0.5 MPa. If you need less force, step down to the 20mm bore's smaller neighbour; if you need more power, step up to the 25mm bore, which provides 206 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X25-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 MBLD20X25-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X25-S FAQ
Yes, the MALD20X25-S is discontinued. The exact drop-in replacement is the MBLD20X25-S, which matches the 20mm bore, 25mm stroke, G1/8 port and mounting. You must upgrade your switches from the older CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The double-rod design means a rod exits both ends, making the annulus area identical on both sides. This yields equal push and pull force: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. The fixed rubber bumper softens end impact but does not lock the load on air loss.
