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

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125-S
The AirTAC MALD20X125-S is a discontinued double-acting, double-rod mini cylinder. Because rods exit both ends, the annulus area is identical on each side, yielding 132 N of equal push and pull force at 0.5 MPa. The exact drop-in replacement is the MBLD20X125-S, which matches the 20 mm bore, 125 mm stroke, G1/8 port, and FA/LB mounting.
This -S SKU includes a magnet for position sensing. The original MALD uses CS1-M or DS1-M switches, while the MBLD upgrade uses CMSG, DMSG, or EMSG sensors. The older MALD body relies on threaded covers, whereas the current MBLD features a riveted rolling-packed body. Both designs use a fixed rubber bumper for end-of-stroke impact absorption, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X125-S |
| 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-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 MBLD20X125-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125-S

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 MALD20X125-S Is Used
PCB Edge Clamping
Clamps printed circuit boards during routing with 132 N of equal force, preventing rotation while a rear rod lifts a shuttle.
Label Applicator Slide
Drives a dual-sided labeling head over 125 mm; the twin rods resist twist and maintain parallelism without a separate guide.
Small Part Ejector
Pushes molded plastic pins out of a die with 185 N at 0.7 MPa, using the rear rod to trigger a CS1-M reed sensor.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125-S with MBLD20X125-S
To replace the MALD20X125-S, order the MBLD20X125-S. Confirm the 20 mm bore, 125 mm stroke, G1/8 port, M8x1.25 rod thread, and FA or LB mounting. Because this is a double-rod cylinder, there is no back-cover or SDB option. Note the sensor family change: the -S magnet still works, but you must upgrade from CS1-M/DS1-M to CMSG/DMSG/EMSG switches.
Size your load on the equal 132 N force at 0.5 MPa. If you need less force, step down to the 16 mm bore (if applicable) or neighbouring smaller body; if you need more, step up to the 25 mm bore, which provides 206 N at 0.5 MPa. At 125 mm stroke, keep the load guided to avoid rod side-load wear.
Upgrade checklist
- ✓ Order the MBLD20X125-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 MBLD20X125-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X125-S FAQ
Yes, the MALD20X125-S is discontinued. The exact drop-in replacement is the MBLD20X125-S, which matches the 20 mm bore, 125 mm stroke, G1/8 port, and FA/LB mounting. You will need to update your position sensors from the older CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
Force is equal because both sides of the piston have the same annulus area due to the twin rods. The exact equal push and pull figures are 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. The cylinder uses a fixed rubber bumper, not an adjustable cushion.
