This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X125 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X125 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 MALD40X125
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125 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 MBLD40X125, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125
The AirTAC MALD40X125 is a discontinued double-acting, double-rod mini cylinder. A 16 mm carbon-steel rod with 20 um hard chrome exits both ends, delivering 528 N of equal force in both directions at 0.5 MPa. The direct drop-in replacement is the MBLD40X125, matching the 40 mm bore, 125 mm stroke, G1/4 port, and mounting.
This SKU has no magnet (-S), so it cannot accept a position sensor. The original MALD features threaded covers and a fixed rubber bumper, while the MBLD upgrade uses a riveted rolling-packed body. Twin rods double the bearing surface and resist rotation, allowing you to mount a cam or tool on the rear rod without sacrificing front-end actuation.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X125 |
| Bore size | Ø40 mm |
| Stroke | 125 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 MBLD40X125 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 MBLD40X125 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125 Is Used
PCB Depaneling Saw
Drives a synchronized blade carriage on a printed circuit board depaneling saw, using the 739 N equal force at 0.7 MPa to push and retract the cut through fiberglass substrates without rotational drift.
Textile Loom Beater
Actuates a dual-sided beater mechanism on a textile loom, where the twin rods maintain parallel alignment across the weaving width and the rear rod carries a flag to trigger weft insertion timing.
Aluminum Extrusion Press
Indexes a clamping jaw on a small aluminum extrusion cutoff press, relying on the 528 N force at 0.5 MPa to hold the profile square while the saw cuts, absorbing end impact via the fixed rubber bumper.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125 with MBLD40X125
To replace the MALD40X125 with the MBLD40X125, confirm the 40 mm bore, 125 mm stroke, PT G1/4 port, and M12x1.25 rod-end thread. Mounting uses FA flange or LB foot brackets directly on the body, as there is no back-cover or SDB option. Because this SKU lacks the -S magnet, you cannot install CS1-M or DS1-M switches; the MBLD upgrade uses CMSG, DMSG, or EMSG sensors if you need position feedback.
Size based on the 528 N equal push and pull force at 0.5 MPa (739 N at 0.7 MPa). If you need less force, step down to the 32 mm bore, which provides 346 N each way at 0.5 MPa. As the largest available bore in this series, there is no larger standard option. The 125 mm stroke is well within the 500 mm maximum, but always ensure your load is guided to prevent side-loading on the twin rods.
Upgrade checklist
- ✓ Order the MBLD40X125 (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 MBLD40X125 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125 FAQ
Yes, the MALD40X125 is discontinued. The exact drop-in replacement is the MBLD40X125, which matches the 40 mm bore, 125 mm stroke, G1/4 port, and mounting. The MBLD upgrades the construction to a riveted rolling-packed body, replacing the original threaded covers.
The push and pull forces are equal: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. This specific MALD40X125 SKU lacks the -S magnet, so it cannot accept a position sensor; the MBLD replacement uses CMSG, DMSG, or EMSG sensors if needed.
