This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X400-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X400-S 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-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400-S 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-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400-S
The AirTAC MALD25X400-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, so push and pull force are equal at 206 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD25X400-S, matching the 25 mm bore, 400 mm stroke, G1/8 port and mounting.
This -S SKU uses the older CS1-M / DS1-M magnet switches, while the MBLD25X400-S upgrades to CMSG / DMSG / EMSG sensors. The MALD has threaded covers, whereas the MBLD uses a riveted rolling-packed body. Its 400 mm stroke exceeds the 300 mm standard, making it a non-standard, made-to-order unit. It relies on a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X400-S |
| 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-S 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-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400-S

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 MALD25X400-S Is Used
PCB Edge Conveyor Lift
Lifts a populated PCB conveyor carriage. The twin rods prevent chassis twist during the 400 mm lift, while the 206 N equal force ensures smooth, balanced vertical motion without drift bias.
Textile Beam Indexer
Shifts a heavy textile beam laterally across a creel. The double-rod design carries a cam flag on the rear rod to trigger an external reed sensor at full extension without adding external tracks.
Packaging Fold Mechanism
Drives a carton folding blade over a 400 mm travel. The fixed rubber bumper absorbs the rapid end-of-stroke impact, while the dual rods resist the torsional load of the blade engaging the cardboard.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400-S with MBLD25X400-S
To replace the MALD25X400-S, order the MBLD25X400-S. Confirm the G1/8 port, M10x1.25 rod-end thread, and FA or LB mounting, as the double-rod body uses no back cover or SDB. The -S magnet requires switching from CS1-M / DS1-M to CMSG / DMSG / EMSG sensors. Size on the 206 N equal force: step down to the 20 mm bore for 132 N, or up to the 32 mm bore for 346 N at 0.5 MPa. At 400 mm, guide the load to prevent rod side-load and premature bearing wear.
Upgrade checklist
- ✓ Order the MBLD25X400-S (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-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X400-S FAQ
Yes, the MALD25X400-S is discontinued. The exact drop-in replacement is the MBLD25X400-S, matching the 25 mm bore, 400 mm stroke, G1/8 port and mounting. You must upgrade the sensor from the older CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
Because a rod exits both ends, both sides have the same annulus area, making push and pull force equal. The ratings are 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. The 400 mm stroke is non-standard and exceeds the 300 mm maximum.
