This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X500 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X500 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 MALD40X500
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X500 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 MBLD40X500, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X500
The AirTAC MALD40X500 is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, so the annulus area is identical on each side. It delivers an equal 528 N of push and pull force at 0.5 MPa. The exact drop-in replacement is the MBLD40X500, matching the 40 mm bore, 500 mm stroke, G1/4 port, and mounting.
This SKU has no magnet (-S), so it cannot take a position sensor. It uses a fixed rubber bumper rather than an adjustable cushion, and its threaded covers differ from the MBLD's riveted rolling-packed body. Twin rods double the bearing surface and resist rotation, letting you mount a cam on the rear rod while the front rod drives the load.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X500 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X500 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X500 |
| Bore size | Ø40 mm |
| Stroke | 500 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 MBLD40X500 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 MBLD40X500 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X500 Is Used
Sliding Gate Actuation
Drives a 500 mm horizontal security gate travel. The twin rods provide anti-rotation stability for the heavy panel, while the 528 N equal force ensures consistent push and pull across the full stroke.
Textile Beam Indexing
Shifts large textile beams laterally on a weaving creel. The rear rod carries an adjustable cam to trip a limit switch at full extension, operating reliably without a built-in magnet.
Dual-Tool Transfer Slide
Powers a 500 mm transfer slide that picks and places heavy cast parts. The double-rod design mounts a gripper on the front and an ejector pin on the rear, doubling the bearing load for long strokes.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X500 with MBLD40X500
To replace this MALD40X500 with the MBLD40X500, confirm the 40 mm bore, 500 mm stroke, G1/4 port, PT thread, and FA or LB mounting (there is no back-cover or SDB option). Since this SKU lacks the -S magnet, it cannot support a sensor; if you need position detection, select an MBLD40X500S and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Size using the equal 528 N force at 0.5 MPa. If you need less force, step down to the 32 mm bore (346 N at 0.5 MPa). This 40 mm bore is the largest available, so you cannot step up. At 500 mm stroke, support the load externally to prevent rod side-load and bearing wear.
Upgrade checklist
- ✓ Order the MBLD40X500 (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 MBLD40X500 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X500 FAQ
Yes, the MALD40X500 is discontinued. The exact drop-in replacement is the MBLD40X500, matching the 40 mm bore, 500 mm stroke, G1/4 port, and mounting. The MBLD uses a riveted rolling-packed body instead of threaded covers, but the force and ratings are the same.
Because it is a double-rod cylinder, force is equal both ways: 528 N push and 528 N pull at 0.5 MPa, and 739 N push and 739 N pull at 0.7 MPa. The maximum force is 108 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke impact absorption and has no adjustable cushion.
