This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X40 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 MALD25X40
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X40 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 MBLD25X40, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X40
The AirTAC MALD25X40 is a discontinued double-acting, double-rod mini cylinder. It delivers equal push and pull force at 206 N each way at 0.5 MPa, using a 25 mm bore and 40 mm stroke. The exact drop-in replacement is the MBLD25X40, matching the bore, stroke, force, G1/8 port, and mounting.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. Unlike the newer riveted MBLD, this legacy MALD uses threaded covers and a fixed rubber bumper. The twin-rod design resists rotation and doubles the bearing load, allowing a rear rod to carry a cam or flag for dual-tooling setups.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X40 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X40 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X40 |
| Bore size | Ø25 mm |
| Stroke | 40 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 MBLD25X40 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 MBLD25X40 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 MALD25X40 Is Used
PCB Shuttle Transfer
Drives a dual-sided shuttle in a PCB routing machine, using the 206 N equal force and anti-rotation twin rods to prevent binding during precise 40 mm transfers.
Label Applicator Cam
Uses the extended rear rod to mount a cam that triggers a mechanical valve, timing a label wipe-down stroke without needing an electronic sensor.
Plastic Mold Ejector
Ejects small plastic parts from a mold cavity, relying on the doubled bearing surface to handle asymmetric side loads without scoring the bore.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X40 with MBLD25X40
Replace the MALD25X40 with the MBLD25X40. Confirm the 25 mm bore, 40 mm stroke, PT G1/8 port, and M10x1.25 rod-end thread. Mount via FA flange or LB foot, as there is no back-cover or SDB option. Because this SKU has no -S magnet, it cannot take a sensor; the MBLD upgrade uses CMSG/DMSG/EMSG switches.
Size on the equal 206 N force at 0.5 MPa. If you need less force, step down to the 20 mm bore (132 N at 0.5 MPa). If you need more, step up to the 32 mm bore (346 N at 0.5 MPa).
Upgrade checklist
- ✓ Order the MBLD25X40 (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 MBLD25X40 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X40 FAQ
Yes, the MALD25X40 is discontinued. The exact drop-in replacement is the MBLD25X40, which matches the 25 mm bore, 40 mm stroke, G1/8 port, and mounting. The MBLD upgrades the body to a riveted rolling-packed design.
The push and pull forces are equal: 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; the MBLD replacement uses CMSG/DMSG/EMSG switches.
