This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X50-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X50-LB 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 MALD25X50-LB
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-LB 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 MBLD25X50-LB, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-LB
The AirTAC MALD25X50-LB is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering equal push and pull force of 206 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD25X50-LB, matching the 25 mm bore, 50 mm stroke, G1/8 port, and LB foot mount.
This SKU has no -S magnet and cannot take 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. Twin rods resist rotation and double the bearing area, while the fixed rubber bumper softens end impacts without acting as a load lock.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-LB Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-LB |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X50-LB |
| Bore size | Ø25 mm |
| Stroke | 50 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 MBLD25X50-LB 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 MBLD25X50-LB 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 MALD25X50-LB Is Used
PCB Depaneling Router
Twin rods resist router bit torque during PCB depaneling, keeping the 206 N cutting axis true without rotational drift.
Textile Yarn Guide
Equal push and pull force drives a yarn guide carriage symmetrically, ensuring consistent tension across the 50 mm travel.
Pick-and-Place Transfer
The rear rod carries a secondary cam to trip an external mechanical valve, sequencing a pick-and-place gripper without sensors.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-LB with MBLD25X50-LB
Replace this MALD25X50-LB directly with the MBLD25X50-LB, confirming the 25 mm bore, 50 mm stroke, G1/8 port, M10x1.25 rod-end thread, and LB foot mount. Because this SKU lacks the -S magnet, it cannot accept a sensor; if you need position detection, step up to the -S version and migrate from CS1-M/DS1-M to CMSG/DMSG/EMSG switches. Size your circuit on the equal 206 N force at 0.5 MPa. If you need less force, step down to the 20 mm bore (132 N @0.5 MPa); if you need more, step up to the 32 mm bore (346 N @0.5 MPa).
Upgrade checklist
- ✓ Order the MBLD25X50-LB (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 MBLD25X50-LB instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-LB FAQ
Yes, the MALD25X50-LB is discontinued. The exact drop-in replacement is the MBLD25X50-LB, matching the 25 mm bore, 50 mm stroke, LB foot mount, and G1/8 port. The MBLD upgrades the body to a riveted rolling-packed design.
Force is equal both ways because the double-rod design gives both sides the same annulus area. Push and pull are both 206 N at 0.5 MPa and 289 N at 0.7 MPa, with a maximum force of 42 kgf at 1.0 MPa. This SKU has no -S magnet and cannot take a position sensor.
