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

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450-S
The AirTAC MALD40X450-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal force both ways at 528 N @0.5 MPa. The exact drop-in replacement is the MBLD40X450-S, matching the 40mm bore, 450mm stroke, G1/4 port, and mounting.
This -S SKU includes a magnet for CS1-M / DS1-M switches; the MBLD upgrade uses CMSG / DMSG / EMSG sensors. The MALD uses threaded covers, while the MBLD features a riveted rolling-packed body. Twin rods resist torsion and double the bearing area, allowing the rear rod to drive a cam or secondary tooling simultaneously.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X450-S |
| 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-S 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-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450-S Is Used
PCB Edge Routing Spindle
Drives a router spindle on a printed circuit board depaneling machine. The twin rods prevent rotational drift during plunge cuts, while the 739 N @0.7 MPa force handles multi-layer FR4 fiberglass cleanly.
Textile Beam Loom Feed
Actuates a tensioning beam on a rapier loom. The double-rod layout lets the rear rod carry a mechanical cam for the take-up mechanism, synchronizing the 450mm stroke with the weaving cycle.
Carton Flap Folder
Folds heavy corrugated carton flaps on a continuous packaging line. The 528 N @0.5 MPa equal push/pull force ensures consistent folding pressure whether extending or retracting across the 450mm span.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450-S with MBLD40X450-S
To replace this MALD40X450-S, order the MBLD40X450-S. Confirm the 40mm bore, 450mm stroke, M12x1.25 rod-end thread, G1/4 port, and FA/LB mounting (no back cover or SDB). The -S magnet requires updating your switches from CS1-M/DS1-M to CMSG/DMSG/EMSG. Size strictly on the 528 N @0.5 MPa equal force. If you need less force, step down to the 32mm bore (346 N @0.5 MPa); this 40mm is the largest available. At 450mm stroke, mount true to guide rails to prevent rod side-load and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD40X450-S (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-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X450-S FAQ
Yes, the MALD40X450-S is discontinued. The exact drop-in replacement is the MBLD40X450-S, matching the 40mm bore, 450mm stroke, G1/4 port, and FA/LB mounting. You must update your sensors: the MALD -S magnet uses CS1-M / DS1-M switches, while the MBLD uses CMSG / DMSG / EMSG.
Because it is a double-rod cylinder, push and pull forces are equal: 528 N @0.5 MPa, 739 N @0.7 MPa, and 108 kgf max @1.0 MPa. It uses a fixed rubber bumper at end-of-stroke for impact absorption; there is no adjustable cushion. It is not a lock and the rod will drift on air loss.
