This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD40X25S, 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 MALD40X25-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X25-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 direct replacement is the MBLD40X25-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X25-S
The AirTAC MALD40X25-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 40 mm bore, generating equal force in both directions at 528 N each way at 0.5 MPa. The direct replacement is the MBLD40X25-S, matching the 25 mm stroke, G1/4 port, and mounting.
This unit features a fixed rubber bumper and an -S magnet for position sensing. Unlike the newer riveted rolling-packed MBLD body, this legacy MALD uses threaded covers. Its -S magnet requires the older CS1-M or DS1-M switches, whereas the MBLD upgrade accepts the CMSG, DMSG, or EMSG sensor families.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X25-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X25-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X25-S |
| Bore size | Ø40 mm |
| Stroke | 25 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 MBLD40X25-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 MBLD40X25-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X25-S Is Used
PCB Depaneling Saw
Drives a synchronized upper and lower blade carriage using both rods, ensuring a clean 528 N cut without board chatter.
Textile Loom Takedown
Feeds fabric evenly from both ends of the loom, using the twin rods to resist rotational twist during high-speed 25 mm indexing.
Injection Mold Ejector
Mounts a rear cam to trigger a mold release sequence, while the front rod pushes the finished plastic part out of the cavity.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X25-S with MBLD40X25-S
To replace this MALD40X25-S, order the MBLD40X25-S. Confirm the 40 mm bore, 25 mm stroke, G1/4 port, M12x1.25 rod-end thread, and PT thread form. Mount directly on the body, or use an FA flange or LB foot, as there is no back-cover or SDB option. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG.
Size based on the equal 528 N force at 0.5 MPa. If you need less force, step down to the 32 mm bore providing 346 N both ways. If you need more, note that 40 mm is the largest MALD bore available. The 16 mm carbon-steel rods with 20 um hard chrome handle the short 25 mm stroke with excellent side-load rigidity.
Upgrade checklist
- ✓ Order the MBLD40X25-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 MBLD40X25-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X25-S FAQ
Yes, the MALD40X25-S is discontinued. The direct replacement is the MBLD40X25-S, which matches the 40 mm bore, 25 mm stroke, G1/4 port, and force ratings. You will need to upgrade your position sensors from the older CS1-M/DS1-M to the newer CMSG/DMSG/EMSG switches.
Because a rod exits both ends, the piston sees the same annulus area on both sides, making push and pull force identical. The figures are 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion or a load-holding lock.
