This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X30 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 MALD20X30
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30 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 MBLD20X30, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30
The AirTAC MALD20X30 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 20 mm bore, producing equal push and pull force of 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X30, matching the 30 mm stroke, G1/8 port, and mounting footprint.
This twin-rod layout doubles the bearing load and resists torsion, making it ideal for anti-rotation slides and rear-cam actuation. The original MALD uses threaded covers and a fixed rubber bumper; the MBLD upgrade shifts to a riveted rolling-packed body. This base SKU has no magnet, so it cannot accept a position sensor.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X30 |
| Bore size | Ø20 mm |
| Stroke | 30 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 MBLD20X30 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 MBLD20X30 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30 Is Used
PCB Shuttle Transfer
Uses the equal 132 N push and pull to shuttle light printed circuit board trays between pick-and-place heads without rotation drift.
Wire Termination Press
The twin 8 mm rods absorb torsional stress during crimping, while the 30 mm stroke delivers rapid terminal insertion.
Label Applicator Cam
The rear rod extension acts as a precise cam trigger for a mechanical label dispenser, keeping the front rod dedicated to the 132 N wipe cycle.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30 with MBLD20X30
To replace the MALD20X30, specify the MBLD20X30 and confirm the 20 mm bore, 30 mm stroke, M8x1.25 rod-end thread, and PT G1/8 port. Mounting is limited to FA flange or LB foot, as there is no back cover or SDB option. Size your load on the equal 132 N force at 0.5 MPa. If you need less force, there is no smaller standard MALD bore. If you need more, step up to the 25 mm bore, which provides 206 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X30 (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 MBLD20X30 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30 FAQ
Yes, the MALD20X30 is discontinued. The exact drop-in replacement is the MBLD20X30, which matches the 20 mm bore, 30 mm stroke, G1/8 port, and FA/LB mounting. The MBLD upgrades the body to a riveted rolling-packed design and, if you add the -S code, supports CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M.
Because a rod exits both ends, the annulus piston area is identical on both sides, making force equal both ways. The exact figures are: 132 N push and 132 N pull at 0.5 MPa, 185 N each way at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. This base MALD20X30 SKU has no -S magnet and cannot take a position sensor.
