This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD20X250, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct 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 direct 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.

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 direct 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.
