This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X125 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X125 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 MALD20X125
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125 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 MBLD20X125, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125
The AirTAC MALD20X125 is a discontinued double-acting, double-rod mini cylinder with a 20 mm bore and 125 mm stroke. A rod exits both ends, so the annulus area is identical on both sides, yielding exactly 132 N of equal push and pull force at 0.5 MPa. It drops directly into the MBLD20X125, which retains the same bore, stroke, port, and mounting.
This legacy unit uses threaded covers and a fixed rubber bumper. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The modern MBLD20X125 upgrade replaces the threaded assembly with a riveted rolling-packed body and switches to the CMSG, DMSG, or EMSG sensor family if sensing is added.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X125 |
| Bore size | Ø20 mm |
| Stroke | 125 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 MBLD20X125 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 MBLD20X125 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125 Is Used
PCB Pick-and-Place
Drives a dual-ended vacuum pick head for electronic board assembly, using the 132 N equal force to lift and place components without rotational drift.
Textile Y Guide
Actuates a yarn threading carriage where the rear rod carries a cam, relying on the twin rods to prevent binding over the 125 mm travel.
Label Dispenser
Pins and releases a film web in a packaging machine, using the fixed rubber bumper to soften the 125 mm stroke ends without adjustable cushions.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125 with MBLD20X125
Replace this MALD20X125 with the drop-in MBLD20X125 by confirming the 20 mm bore, 125 mm stroke, G1/8 port, PT thread, and FA or LB mounting. Since this is a non-magnet SKU, it cannot hold a sensor; upgrading to the MBLD lets you add a CMSG, DMSG, or EMSG switch. Size your load on the 132 N equal force both ways. If you need less force, step down to the 20 mm bore's nearest smaller neighbour (confirm from datasheet); if you need more, step up to the 25 mm bore, which provides 206 N each way at 0.5 MPa. At 125 mm stroke, ensure your external guides absorb any rod side-load to prevent premature bearing wear.
Upgrade checklist
- ✓ Order the MBLD20X125 (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 MBLD20X125 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125 FAQ
Yes, the MALD20X125 is discontinued. The exact drop-in replacement is the MBLD20X125, which matches the 20 mm bore, 125 mm stroke, G1/8 port, and mounting. The MBLD upgrades the body to a riveted rolling-packed design and uses CMSG, DMSG, or EMSG sensors instead of the older threaded cover design.
Because a rod exits both ends, the effective piston area is the same annulus on both sides, making push and pull force identical. The full figure set is 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. This SKU has no magnet, so it cannot accept a position sensor.
