This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X300 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X300 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 MALD20X300
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300 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 MBLD20X300, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300
The AirTAC MALD20X300 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal force in both directions at 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X300, matching the 20 mm bore, 300 mm stroke, G1/8 port, and mounting.
This unit features a fixed rubber bumper and threaded covers, whereas the MBLD upgrade uses a riveted rolling-packed body. This SKU lacks the -S magnet, so it cannot accept a position sensor. The twin rods resist rotation and double the bearing load, while the rear rod can mount a flag or tool. At 300 mm stroke, the long twin rods require a guide to prevent side-load wear.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X300 |
| Bore size | Ø20 mm |
| Stroke | 300 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 MBLD20X300 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 MBLD20X300 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 MALD20X300 Is Used
PCB Edge Guiding
Uses the 132 N equal force and twin rods to straighten circuit boards on a conveyor without rotational drift.
Film Slitter Tracking
Mounts a cam on the rear rod to hold tension on packaging film, relying on anti-rotation over the 300 mm stroke.
Dual-Pick Tooling Slide
Drives a guided pick-and-place head for small electronic parts, using the fixed rubber bumper to soften end impacts.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300 with MBLD20X300
To replace the MALD20X300, specify MBLD20X300 to retain the 20 mm bore, 300 mm stroke, G1/8 port, and M8x1.25 rod thread. Confirm your FA or LB mounting, as there is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot take a sensor; if you need position detection, the MBLD uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
Size on the equal force of 132 N at 0.5 MPa. If you need less force, there is no smaller bore in this series. If you need more force, step up to the 25 mm bore, which provides 206 N at 0.5 MPa. Since the stroke is 300 mm, add an external guide to handle side loads and prevent binding.
Upgrade checklist
- ✓ Order the MBLD20X300 (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 MBLD20X300 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300 FAQ
Yes, the MALD20X300 is discontinued. The exact drop-in replacement is the MBLD20X300, which matches the 20 mm bore, 300 mm stroke, G1/8 port, and mounting. The MBLD upgrades the body to a riveted rolling-packed design but retains the same force ratings.
Force is equal both ways: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. This specific SKU lacks the -S magnet, so it cannot accept a position sensor; the MBLD replacement uses CMSG/DMSG/EMSG switches.
