This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X400 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X400 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 MALD25X400
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400 is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø25mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD25X400, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400
The AirTAC MALD25X400 is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends, providing equal force both ways at 206 N at 0.5 MPa. The exact drop-in replacement is the MBLD25X400, matching the 25 mm bore, 400 mm stroke, G1/8 port, and mounting.
This SKU has no magnet (-S) and cannot accept a position sensor. The original MALD uses threaded covers and older CS1-M/DS1-M switches, while the MBLD upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. The 400 mm stroke exceeds the 300 mm standard maximum, making it a non-standard, made-to-order length.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X400 |
| Bore size | Ø25 mm |
| Stroke | 400 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 300 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD25X400 carries the same ratings.
Output Force — Equal Both Ways (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | 289 N |
| Max (@1.0 MPa) | 42 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD25X400 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400 Is Used
PCB Edge Conveyor
Drives a dual-belt conveyor edge in SMT lines. The twin rods prevent chassis rotation over the 400 mm travel, ensuring parallel board transfer with 206 N of equal push-pull force.
Textile Beam Indexer
Shifts a warp beam carriage in a weaving mill. The rear rod mounts a mechanical flag to trip a limit switch, using the fixed rubber bumper to soften the 400 mm end-of-stroke impact.
Film Slitter Cut-off
Actuates a dual-blade cut-off on a packaging film slitter. The double-rod design adds bearing load capacity to resist blade drag, while the 289 N force at 0.7 MPa shears heavy laminate.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400 with MBLD25X400
To replace the MALD25X400 with the MBLD25X400, confirm the 25 mm bore, 400 mm stroke, G1/8 port, PT thread, and FA or LB mounting. This double-rod cylinder outputs 206 N each way at 0.5 MPa. If you need less force, step down to the 20 mm bore (132 N). If your application needs more power, step up to the 32 mm bore (346 N). Because the 400 mm stroke is non-standard and exceeds the 300 mm max, carefully support the rod to prevent side-load binding on long extensions.
Upgrade checklist
- ✓ Order the MBLD25X400 (same bore/stroke/force)
- ✓ Force equal both ways (206 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 MBLD25X400 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400 FAQ
Yes, the MALD25X400 is discontinued. The exact drop-in replacement is the MBLD25X400, which matches the 25 mm bore, 400 mm stroke, G1/8 port, and equal 206 N force. The MBLD upgrades to a riveted rolling-packed body.
The force is equal both ways: 206 N at 0.5 MPa and 289 N at 0.7 MPa, with a maximum of 42 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion. It cannot hold a load on air loss; the rod will drift.
