This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X150-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X150-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 MALD40X150-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-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 MBLD40X150-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-S
The AirTAC MALD40X150-S double-acting double-rod cylinder is discontinued. The exact drop-in replacement is the MBLD40X150-S, matching the 40 mm bore, 150 mm stroke, G1/4 port, and mounting. Because twin rods exit both ends, the annulus area is identical on each side, yielding 528 N of thrust and pull force at 0.5 MPa.
This MALD40X150-S uses a fixed rubber bumper, not an adjustable cushion. It has threaded covers and a -S magnet for CS1-M / DS1-M switches. The MBLD upgrade improves durability with a riveted rolling-packed body and updates sensing to CMSG / DMSG / EMSG switches. The rear rod resists torsion and can carry a cam or secondary tool.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X150-S |
| Bore size | Ø40 mm |
| Stroke | 150 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 MBLD40X150-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 MBLD40X150-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-S
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×150 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLD uses CMSG/DMSG/EMSG). |
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 MALD40X150-S Is Used
Gripper Synchronization
Drives opposing gripper jaws on CNC lathe loaders, using the 528 N equal both-ways force to clamp heavy forged bar stock without rotational drift.
Dual-End Tooling
Mounts a forming punch on the front rod and a rear cam to trigger a limit valve on a metal stamping press, cutting cycle time by combining motions.
Indexing Gate Slide
Shifts a heavy 150 mm stroke safety chute gate on a packaging line, relying on the twin 16 mm rods to resist torsion and guide the load smoothly.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-S with MBLD40X150-S
Replace this MALD40X150-S with the MBLD40X150-S. Confirm the 40 mm bore, 150 mm stroke, M12x1.25 rod-end thread, PT G1/4 port, and FA or LB mounting. It has no back cover or SDB. Because the -S magnet is present, your old CS1-M / DS1-M sensors must change to CMSG / DMSG / EMSG switches on the new riveted body.
Size on the equal 528 N thrust and pull at 0.5 MPa. To step down, the 32 mm bore gives 346 N each way. To step up, the 40 mm is the largest MALD bore, so confirm from datasheet if you need a larger double-rod series. At 150 mm stroke, ensure your load is guided to avoid rod side-loading.
Upgrade checklist
- ✓ Order the MBLD40X150-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 MBLD40X150-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-S FAQ
Yes, the MALD40X150-S is discontinued. The exact drop-in replacement is the MBLD40X150-S. It matches the 40 mm bore, 150 mm stroke, G1/4 port, and mounting. The upgrade changes the threaded covers to a riveted rolling-packed body, and the -S magnet sensor family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG.
As a double-rod cylinder, push and pull forces are equal: 528 N each way at 0.5 MPa, and 739 N each way at 0.7 MPa. The maximum force is 108 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion, and cannot hold a load on air loss.
