This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD40X600S, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALD40X600S
The AirTAC MALD Aluminum Alloy Mini Cylinder MALD40X600S 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 direct replacement is the MBLD40X600S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X600S
The AirTAC MALD40X600S is a discontinued double-acting, double-rod mini cylinder. As a 40mm bore unit, it delivers an equal 528 N of push and pull force at 0.5 MPa (739 N at 0.7 MPa) through its G1/4 port. The direct replacement is the MBLD40X600S, matching the bore, stroke, and mounting. The 600mm stroke exceeds the 500mm standard maximum, making this a non-standard, made-to-order configuration.
Twin Ø16mm hard-chrome steel rods exit both threaded covers, providing high anti-rotation resistance and doubling the bearing load for guided sliding. The -S magnet supports legacy CS1-M / DS1-M reed switches, whereas the MBLD upgrade shifts to CMSG / DMSG / EMSG sensors within a riveted rolling-packed body. Impact is managed by a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X600S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X600S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X600S |
| Bore size | Ø40 mm |
| Stroke | 600 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 MBLD40X600S 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 MBLD40X600S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X600S Is Used
PCB Edge Conveyor Transfer
Drives a 600mm guided slide for electronics line transitions, using the twin rods to prevent binding and delivering 528 N of equal force to push and pull panels smoothly.
Textile Beam Indexing
Shifts heavy fabric beams across a 600mm span; the rear rod mounts a cam for sequencing while the front rod handles the 739 N transfer load at 0.7 MPa.
Packaging Pouch Forming
Operates a dual-tooling forming jaw that travels 600mm, relying on the fixed rubber bumper to soften repetitive end-impact without drifting under air loss.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X600S with MBLD40X600S
To replace this MALD40X600S with the MBLD40X600S, verify your G1/4 port, M12x1.25 rod-end thread, and FA or LB mounting (there is no back-cover or SDB option). The -S magnet requires a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. Size using the equal-both-ways force: if 528 N at 0.5 MPa is excessive, step down to the 32mm bore (346 N); if you need more power, 40mm is the largest available. Because the 600mm stroke exceeds the 500mm standard, ensure external guide rails are used to prevent rod side-loading and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD40X600S (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 MBLD40X600S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X600S FAQ
Yes, the MALD40X600S is discontinued. The direct replacement is the MBLD40X600S, which matches the 40mm bore, 600mm stroke, G1/4 port, and mounting. You will need to upgrade your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
Because a rod exits both ends, the piston sees the same annulus area in each direction, making push and pull force identical. The ratings are 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
