This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X250 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X250 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 MALD40X250
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X250 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 MBLD40X250, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X250
The AirTAC MALD40X250 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 40mm bore, yielding equal push and pull force of 528N each way at 0.5MPa. The exact drop-in replacement is the MBLD40X250, matching the 250mm stroke, G1/4 port, and mounting.
This model has no -S magnet code, so it cannot accept a position sensor. The original MALD uses threaded covers and fixed rubber bumpers, whereas the MBLD upgrade features a riveted rolling-packed body. Twin rods double the bearing area and resist rotation, allowing a flag or cam to mount on the rear rod.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X250 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X250 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X250 |
| Bore size | Ø40 mm |
| Stroke | 250 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 MBLD40X250 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 MBLD40X250 matches these values.

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 MALD40X250 Is Used
PCB Edge-Guide Transfer
Drives a synchronized transfer arm in a PCB conveyor. The twin rods prevent yaw during the 250mm traverse, and the 528N force moves populated boards without deflection.
Injection Mold Ejection
Mounts a secondary ejector on a molding press. The rear rod carries a stripper cam while the front rod pushes the part, using equal force to strip and eject simultaneously.
Loom Weft Feeder
Actuates a yarn feeder guide on an industrial weaving loom. The fixed rubber bumper absorbs the high-frequency end-of-stroke impact without requiring adjustment.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X250 with MBLD40X250
Replace the MALD40X250 with the MBLD40X250. Confirm the 40mm bore, 250mm stroke, G1/4 port, PT thread, and FA or LB mounting (there is no back-cover or SDB option). Because this SKU lacks the -S magnet, it cannot hold a sensor; the MBLD upgrade uses CMSG/DMSG/EMSG switches.
Size strictly on the equal 528N force at 0.5MPa. To step down, the 32mm bore provides 346N. To step up, the 40mm is the largest available bore, so 528N is your maximum capacity. For the 250mm stroke, ensure external guides handle side-load to prevent binding.
Upgrade checklist
- ✓ Order the MBLD40X250 (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 MBLD40X250 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X250 FAQ
Yes, the MALD40X250 is discontinued. The exact drop-in replacement is the MBLD40X250, which matches the 40mm bore, 250mm stroke, G1/4 port, and mounting.
Force is equal both ways: 528N at 0.5MPa, 739N at 0.7MPa, and a max of 108kgf at 1.0MPa. This SKU has no -S magnet, so it cannot accept a position sensor; the MBLD replacement uses CMSG/DMSG/EMSG switches.
