This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X20S 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 MALD40X20S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X20S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø40mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD40X20S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X20S
The AirTAC MALD40X20S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, so the annulus area is identical on each side, yielding equal force in both directions at 528 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD40X20S, matching the 40mm bore, 20mm stroke, G1/4 port, and mounting.
This -S SKU includes a magnet for CS1-M / DS1-M switches; the MBLD replacement upgrades this to CMSG / DMSG / EMSG sensors. The MALD uses threaded covers and a fixed rubber bumper, whereas the MBLD features a riveted rolling-packed body. With no back cover or SDB option, you mount directly on the body, LB foot, or FA flange. Twin rods resist rotation and double the bearing load for compact guided slides.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X20S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X20S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X20S |
| Bore size | Ø40 mm |
| Stroke | 20 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 500 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD40X20S carries the same ratings.
Output Force — Equal Both Ways (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |
| Max (@1.0 MPa) | 108 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD40X20S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X20S Is Used
PCB Edge-Guided Conveyor
Twin 16mm rods resist rotational twist while shifting fragile printed circuit boards, applying 528 N of equal push and pull force without skewing the belt path.
Dual-End Stacking Tool
The rear rod carries a secondary cam to actuate a parts feeder, while the front rod performs a 20mm stacking lift, using identical 739 N force at 0.7 MPa for both strokes.
Pneumatic Gripper Slide
Mounts directly via FA flange to a robotic jaw, using the fixed rubber bumper to soften rapid 20mm clamping impacts on aluminum extrusions without needing adjustable cushions.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X20S with MBLD40X20S
To replace this MALD40X20S with the MBLD40X20S, confirm the 40mm bore, 20mm stroke, G1/4 port, M12x1.25 rod-end thread, and FA/LB mounting. You must also update your sensor family from the older CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches. Size your application on the equal 528 N force at 0.5 MPa (739 N at 0.7 MPa).
If you need to step down, the neighbouring 32mm bore provides 346 N at 0.5 MPa. As the largest available bore, 40mm is the maximum size for this series, delivering a top-tier 108 kgf max force at 1.0 MPa.
Upgrade checklist
- ✓ Order the MBLD40X20S (same bore/stroke/force)
- ✓ Force equal both ways (528 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 MBLD40X20S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X20S FAQ
Yes, the MALD40X20S is discontinued. The exact drop-in replacement is the MBLD40X20S, which matches the 40mm bore, 20mm stroke, G1/4 port, and equal 528 N force. You only need to update your switches from CS1-M / DS1-M to CMSG / DMSG / EMSG sensors.
The double-rod design provides equal force both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. It uses a G1/4 port, a 16mm hard-chrome rod, M12x1.25 rod-end thread, and a fixed rubber bumper. It operates between 0.1-1.0 MPa at 30-800 mm/s.
