This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X250 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X250 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 MALD20X250
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250 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 MBLD20X250, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250
The AirTAC MALD20X250 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, so push and pull forces are equal at 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X250, matching the 20mm bore, 250mm stroke, G1/8 port, and mounting.
This SKU has no magnet and cannot take a position sensor. The original MALD uses threaded covers and fixed rubber bumpers, while the MBLD upgrade features a riveted rolling-packed body. The twin rods provide anti-rotation guidance and allow mounting a cam or flag on the rear rod.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X250 |
| Bore size | Ø20 mm |
| Stroke | 250 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 MBLD20X250 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 MBLD20X250 matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250

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 MALD20X250 Is Used
PCB Degating Press
Uses the 132 N equal push and pull to cleanly shear plastic gates from PCBs without rotating the fixture, leveraging the twin rods for precise anti-rotation guidance.
Label Dispenser Cam
The rear extending rod drives a mechanical cam for a timing belt label dispenser, operating at 30-800 mm/s with fixed rubber bumpers absorbing the end impact.
Thin-Film Web Splicer
Guides a delicate film web splicing head across a 250mm stroke, using the double-rod bearing layout to prevent chassis yaw during high-speed indexing.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250 with MBLD20X250
To replace the MALD20X250 with the MBLD20X250, confirm the 20mm bore, 250mm stroke, G1/8 PT port, and FA/LB mounting (there is no back cover or SDB option). This non-magnet SKU cannot accept a sensor; upgrading to an MBLD -S version changes the switch family from CS1-M/DS1-M to CMSG/DMSG/EMSG. Size on the 132 N equal force; stepping down to the 16mm bore yields roughly 80 N, while stepping up to the 25mm bore provides 206 N at 0.5 MPa. At 250mm stroke, ensure external guides support side loads to prevent rod binding.
Upgrade checklist
- ✓ Order the MBLD20X250 (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 MBLD20X250 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250 FAQ
Yes, the MALD20X250 is discontinued. The exact drop-in replacement is the MBLD20X250, which matches the 20mm bore, 250mm stroke, G1/8 port, and mounting. The MBLD upgrades the body to a riveted rolling-packed design from the original threaded covers.
Force is equal because both sides of the piston have the same annulus area due to the double-rod design. The figures are: 132 N push and pull at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. This SKU lacks a magnet (-S), so it cannot accept a position sensor.
