This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X150 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X150 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 MALD20X150
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150 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 MBLD20X150, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150
The AirTAC MALD20X150 is a discontinued double-acting, double-rod mini cylinder. It delivers 132 N of force in both directions at 0.5 MPa because twin rods exit both ends, yielding identical annulus areas. The direct drop-in replacement is the MBLD20X150, matching the 20 mm bore, 150 mm stroke, and G1/8 port.
This SKU has no magnet, so it cannot accept position sensors. The original MALD uses threaded covers, while the MBLD upgrade features a riveted rolling-packed body. It relies on a fixed rubber bumper for end-of-stroke damping and mounts directly via the body or an FA/LB bracket, as there is no back cover or SDB option.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X150 |
| Bore size | Ø20 mm |
| Stroke | 150 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 MBLD20X150 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 MBLD20X150 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150 Is Used
PCB Depaneling Saw
Drives a synchronized blade carriage with 132 N of equal push and pull force, ensuring the twin rods resist rotational twist during precise board cuts.
Connector Insertion Press
Uses the rear exiting rod to mount a mechanical flag, confirming part seating while the front rod applies 185 N at 0.7 MPa to seat pin headers.
Gripper Slide Actuator
Powers a dual-tooling pick and place slide where the 150 mm stroke transfers small plastic mouldings, relying on the fixed rubber bumper to soften impacts.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150 with MBLD20X150
To replace the MALD20X150 with the MBLD20X150, confirm the 20 mm bore, 150 mm stroke, G1/8 port, and PT thread. Because this is a non-magnet SKU, you lose sensor capability unless you specify an MBLD20X150S and upgrade to CMSG/DMSG/EMSG switches (the MALD-S used CS1-M/DS1-M). Size using the equal 132 N force at 0.5 MPa. If you need less force, step down is not an option as 20 mm is the smallest bore. To step up, the 25 mm bore provides 206 N at 0.5 MPa. At 150 mm stroke, guide the load externally to prevent rod side-load and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD20X150 (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 MBLD20X150 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150 FAQ
Yes, the MALD20X150 is discontinued. The exact drop-in replacement is the MBLD20X150, which matches the 20 mm bore, 150 mm stroke, and G1/8 port. The MBLD upgrades the construction with a riveted rolling-packed body instead of threaded covers.
The force is identical in both directions because twin rods exit both ends, making the piston area annular on both sides. The ratings are 132 N push and 132 N pull at 0.5 MPa, 185 N push and 185 N pull at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept a position sensor.
