This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD40X225, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALD40X225
The AirTAC MALD Aluminum Alloy Mini Cylinder MALD40X225 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 direct replacement is the MBLD40X225, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225
The AirTAC MALD40X225 is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends of the 40mm bore, generating 528 N of equal force both ways at 0.5 MPa (108 kgf max at 1.0 MPa). The direct replacement is the MBLD40X225, matching the 225mm stroke, G1/4 port, and mounting.
This SKU has no -S magnet and cannot accept a position sensor. The original MALD uses threaded covers and a fixed rubber bumper, whereas the MBLD upgrade features a riveted rolling-packed body. Twin rods provide high anti-rotation resistance and double the bearing load capacity for guided slides.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X225 |
| Bore size | Ø40 mm |
| Stroke | 225 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 MBLD40X225 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 MBLD40X225 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 MALD40X225 Is Used
PCB Edge-Routing Fixture
Uses the 528 N equal both-ways force to clamp and release router boards, twin rods prevent chuck rotation during high-speed spindle plunges.
Textile Loom Beam Shift
Moves the heavy warp beam laterally; the twin 16mm rods handle the heavy bearing load while the fixed rubber bumper softens the end impact.
Bottling Line Divertor
Drives a dual-sided divertor gate for 225mm travel; rear rod carries a cam to actuate external mechanical valves without needing a sensor.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225 with MBLD40X225
To replace the MALD40X225, specify the MBLD40X225 to retain the 40mm bore, 225mm stroke, G1/4 port, M12x1.25 rod-end thread, and FA/LB mounting. This SKU lacks the -S magnet, so no sensor is used; if sensing is required, move to an MBLD40X225S and the CMSG/DMSG/EMSG switch family. The MALD has no back cover or SDB option.
Size using the equal-both-ways force: 528 N at 0.5 MPa or 739 N at 0.7 MPa. To step down, the 32mm bore neighbor provides 346 N at 0.5 MPa. At 225mm stroke, ensure external guides support side loads to prevent rod binding.
Upgrade checklist
- ✓ Order the MBLD40X225 (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 MBLD40X225 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225 FAQ
Yes, the MALD40X225 is discontinued. The direct replacement is the MBLD40X225, matching the 40mm bore, 225mm stroke, G1/4 port, and force. The MBLD upgrades the threaded covers to a riveted rolling-packed body.
Force is equal because a rod exits both ends, making the piston area an annulus on both sides. Push and pull forces are identical: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 108 kgf max at 1.0 MPa. This SKU has no magnet and cannot take a sensor.
