This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X225S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X225S 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 MALD40X225S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225S 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 MBLD40X225S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225S
The AirTAC MALD40X225S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal push and pull force of 528 N each way at 0.5 MPa (108 kgf max). The exact drop-in replacement is the MBLD40X225S, matching the 40mm bore, 225mm stroke, G1/4 port, and mounting.
This -S SKU includes a magnet for CS1-M or DS1-M switches; the MBLD upgrade switches to CMSG / DMSG / EMSG sensors. Unlike the threaded covers on this MALD, the MBLD uses a riveted rolling-packed body. With no back cover or SDB option, you mount directly via the body or FA/LB brackets.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X225S |
| 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 MBLD40X225S 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 MBLD40X225S 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 MALD40X225S Is Used
PCB Edge Routing
Drives a dual-spindle routing head on a PCB depaneling machine. The twin rods prevent spindle rotation during high-speed routing, using the 739 N force at 0.7 MPa to hold the cutter steady.
Glass Lifting Jig
Powers a synchronous vacuum pad lifter for architectural glass. The equal 528 N force both ways ensures the pad lowers and retracts identically, while the rear rod carries a flag for a home sensor.
Textile Guiding
Actuates a fabric edge-guide carriage in a textile mill. The fixed rubber bumper absorbs the repetitive end-of-stroke impact at high cycle rates without requiring adjustment.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225S with MBLD40X225S
To replace the MALD40X225S with the MBLD40X225S, confirm the 40mm bore, 225mm stroke, M12x1.25 rod-end thread, G1/4 port, and FA/LB mounting. The -S magnet requires changing your CS1-M / DS1-M switches to CMSG / DMSG / EMSG. Size strictly on the 528 N equal force at 0.5 MPa. Stepping down, the 32mm bore provides 346 N; stepping up is not possible as 40mm is the largest MALD size. At 225mm stroke, ensure external guides support side loads to prevent rod binding.
Upgrade checklist
- ✓ Order the MBLD40X225S (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 MBLD40X225S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X225S FAQ
Yes, the MALD40X225S is discontinued. The exact drop-in replacement is the MBLD40X225S, which matches the 40mm bore, 225mm stroke, 528 N equal force, and G1/4 port. You must upgrade your CS1-M / DS1-M sensors to the CMSG / DMSG / EMSG family.
Because a rod exits both ends, both sides have the same annulus area, making push and pull force identical. The figures are 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. The fixed rubber bumper softens end impacts but does not lock the load on air loss.
