This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X30S 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 MALD20X30S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30S 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 MBLD20X30S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30S
The AirTAC MALD20X30S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal push and pull force of 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X30S, matching the 20 mm bore, 30 mm stroke, G1/8 port, and mounting.
This SKU includes the -S magnet for position sensing. The legacy MALD uses CS1-M / DS1-M switches, while the MBLD replacement uses CMSG / DMSG / EMSG sensors. The old threaded covers are replaced by a riveted rolling-packed body on the MBLD. Twin rods resist rotation and double the bearing load, allowing the rear rod to carry a cam or flag.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X30S |
| 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 MBLD20X30S 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 MBLD20X30S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30S Is Used
PCB Edge Clamping
Clamps printed circuit boards during routing. The twin rods prevent chuck rotation, ensuring the 132 N force holds the panel square without twisting.
Dual-End Pick and Place
Drives a small pick-and-place shuttle where the rear rod carries a cam to trip an external mechanical valve, saving space on the 30 mm stroke.
Label Dispenser Pusher
Pushes a label wiper arm with equal push and pull force, preventing the arm from binding in its guide during the 30 mm travel.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30S with MBLD20X30S
To replace the MALD20X30S, specify the MBLD20X30S. Confirm the 20 mm bore, 30 mm stroke, M8x1.25 rod-end thread, and PT G1/8 port. The -S magnet means you must upgrade your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG. Mounting uses FA or LB only; there is no back cover or SDB option.
Size on the equal 132 N force. If you need less force, step down to the next smaller bore (if available) or check the 20 mm specs. If you need more force, step up to the 25 mm bore, which provides 206 N each way at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X30S (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 MBLD20X30S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X30S FAQ
Yes, the MALD20X30S is discontinued. The exact drop-in replacement is the MBLD20X30S, which matches the 20 mm bore, 30 mm stroke, G1/8 port, and force. You will need to update your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The MALD20X30S is a double-rod cylinder, so push and pull force are equal: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion.
