This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X225 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X225 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 MALD40X225
The AirTAC 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 drop-in 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 exact drop-in 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 exact drop-in 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.
