This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X70 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X70 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 MALD40X70
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X70 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 MBLD40X70, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X70
The AirTAC MALD40X70 is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends of the 40mm bore, yielding equal push and pull force of 528 N each way at 0.5 MPa. The direct drop-in replacement is the MBLD40X70, matching the 70mm stroke, G1/4 port, and mounting.
This SKU has no magnet and cannot accept a position sensor. The original MALD uses threaded covers and fixed rubber bumpers for end-of-stroke impact absorption. The MBLD upgrade shifts to a riveted rolling-packed body; if sensing is needed, the MBLD-S uses modern CMSG/DMSG/EMSG switches rather than the legacy CS1-M/DS1-M. Twin rods resist rotation and double the bearing load, allowing the rear rod to drive a cam or secondary tool.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X70 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X70 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X70 |
| Bore size | Ø40 mm |
| Stroke | 70 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 MBLD40X70 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 MBLD40X70 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 MALD40X70 Is Used
PCB Depaneling Router
Twin rods resist cutting torque on a depaneling spindle, keeping the 528 N force true without rod twist during board separation.
Textile Beam Indexer
Drives a cam on the rear rod to trip a thread break sensor, using the equal both-ways force to advance the warp beam smoothly.
Bottle Capping Head
Applies 739 N of equal torque-limited pressure at 0.7 MPa for capping, while the second rod stabilizes the chuck against cap rotation.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X70 with MBLD40X70
Replace the MALD40X70 with the MBLD40X70, confirming the 40mm bore, 70mm stroke, G1/4 port, and M12x1.25 rod-end thread. Mounting uses FA flange or LB foot on the body; there is no back-cover or SDB option. Because this is a non-magnet SKU, it cannot carry a sensor.
Size strictly on the equal 528 N force at 0.5 MPa. To step down, the 32mm bore neighbor provides 346 N each way at 0.5 MPa. The 40mm bore is the largest in this mini-series, so no larger neighbor exists. The fixed rubber bumper softens end impact but provides no load holding on air loss.
Upgrade checklist
- ✓ Order the MBLD40X70 (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 MBLD40X70 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X70 FAQ
Yes, the MALD40X70 is discontinued. The exact drop-in replacement is the MBLD40X70, matching the 40mm bore, 70mm stroke, G1/4 port, and mounting. The MBLD upgrades to a riveted rolling-packed body.
Force is equal both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a max of 108 kgf at 1.0 MPa. It uses a 16mm carbon-steel rod, M12x1.25 rod-end thread, fixed rubber bumpers, and has no magnet so it cannot take a sensor.
