This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X400-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X400-S 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 MALD40X400-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400-S 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 MBLD40X400-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400-S
The AirTAC MALD40X400-S is a discontinued double-acting double-rod cylinder. A rod exits both ends, delivering 528 N of equal force both ways at 0.5 MPa. The exact drop-in replacement is the MBLD40X400-S, matching the 40mm bore, 400mm stroke, G1/4 port, and mounting.
This -S SKU includes a magnet for CS1-M / DS1-M switches; the MBLD upgrade uses CMSG / DMSG / EMSG sensors. The MALD uses threaded covers, while the MBLD features a riveted rolling-packed body. A fixed rubber bumper absorbs end impacts, and twin rods resist rotation while allowing a rear-mounted flag or cam.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X400-S |
| Bore size | Ø40 mm |
| Stroke | 400 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 MBLD40X400-S 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 MBLD40X400-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400-S

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 MALD40X400-S Is Used
PCB Edge Conveyor Tracking
Uses the 528N equal force to clamp electronic panels steadily. The twin rods prevent chassis rotation during continuous indexing.
Textile Yarn Guide Carriage
Mounts a rear cam to trigger mechanical thread cutters. The 400mm stroke spans wide weaving looms without rotational drift.
Packaging Pouch Transfer
Synchronizes dual tooling heads on a vertical form-fill machine. The fixed rubber bumper softens the 400mm travel stop impact.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400-S with MBLD40X400-S
Replace this MALD40X400-S directly with the MBLD40X400-S. Confirm the 40mm bore, 400mm stroke, M12x1.25 rod-end thread, G1/4 port, and FA or LB mounting (there is no back cover or SDB option). The -S magnet requires updating your sensor stock from CS1-M / DS1-M to CMSG / DMSG / EMSG switches.
Size your load using the equal force rating of 528 N at 0.5 MPa. If you need less force, step down to the 32mm bore providing 346 N. If you need more, note that 40mm is the largest available bore. At 400mm stroke, maintain parallel guide rails to prevent rod side-loading and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD40X400-S (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 MBLD40X400-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X400-S FAQ
Yes, the MALD40X400-S is discontinued. The exact drop-in replacement is the MBLD40X400-S, which matches the 40mm bore, 400mm stroke, 528N force, and G1/4 port. You will only need to update your sensors from CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
Because a rod exits both ends, the piston sees the same annulus area on each side, making push and pull force equal. The figures are 528N at 0.5 MPa, 739N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. The fixed rubber bumper softens end-of-stroke impact but does not lock the load on air loss.
