This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X450 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X450 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 MALD40X450
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450 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 MBLD40X450, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450
The AirTAC MALD40X450 is a discontinued double-acting, double-rod pneumatic cylinder. A 16mm carbon-steel rod exits both ends, delivering an equal 528 N push and pull force at 0.5 MPa. The exact drop-in replacement is the MBLD40X450, matching the 40mm bore, 450mm stroke, G1/4 port, and mounting.
This SKU lacks the -S magnet code, so it cannot accept a position sensor. The original MALD uses threaded covers and fixed rubber bumpers, while the MBLD upgrade features a riveted rolling-packed body. Twin rods provide high anti-rotation resistance and allow mounting a rear tool or cam. At 450mm stroke, the extended twin rods demand strict guide alignment to prevent side-load wear.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X450 |
| Bore size | Ø40 mm |
| Stroke | 450 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 MBLD40X450 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 MBLD40X450 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450 Is Used
Servo-Drive Slitters
Guides the cutting head on a paper slitter. The twin rods prevent blade yaw under the 528 N load, ensuring a clean 450mm cut path.
Bottling Line Diverters
Actuates a sorting gate to redirect glass bottles. The equal both-ways force ensures smooth push and return across the 450mm travel.
PCB Conveyor Stops
Raises a hard stop for populated PCB assemblies. The rear rod carries a fixed cam, and the fixed rubber bumper absorbs end impact without adjustment.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450 with MBLD40X450
Replace this MALD40X450 with the MBLD40X450. Verify your G1/4 port, M12x1.25 rod-end thread, and FA or LB mounting. This SKU has no -S magnet, so it cannot support a sensor; if you need sensing, order an MBLD40X450S and use CMSG/DMSG/EMSG switches instead of the old CS1-M/DS1-M. Size strictly on the equal 528 N force at 0.5 MPa. If you need less force, step down to the 32mm bore (346 N). If you need more, step up to the 40mm bore's maximum 108 kgf at 1.0 MPa. For this 450mm stroke, ensure your guide supports the extended rods to avoid binding.
Upgrade checklist
- ✓ Order the MBLD40X450 (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 MBLD40X450 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450 FAQ
Yes, the MALD40X450 is discontinued. The exact drop-in replacement is the MBLD40X450, matching the 40mm bore, 450mm stroke, G1/4 port, and equal force. The MBLD upgrades the threaded covers to a riveted rolling-packed body.
Force is equal both ways: 528 N at 0.5 MPa and 739 N at 0.7 MPa. The maximum force is 108 kgf at 1.0 MPa. This unit has no -S magnet, so it cannot accept a position sensor.
