This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X125-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X125-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 MALD40X125-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125-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 MBLD40X125-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125-S
The AirTAC MALD40X125-S double-acting, double-rod cylinder is discontinued. Its exact drop-in replacement is the MBLD40X125-S, matching the 40mm bore, 125mm stroke, 528N equal force, and G1/4 port. Because twin rods exit both ends, push and pull forces are identical at 528 N each way at 0.5 MPa.
This model uses a fixed rubber bumper rather than an adjustable cushion, absorbing end-of-stroke impact without acting as a load lock. The original MALD features threaded covers and a -S magnet compatible with CS1-M / DS1-M switches. The MBLD upgrade shifts to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors for modern detection.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X125-S |
| Bore size | Ø40 mm |
| Stroke | 125 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 MBLD40X125-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 MBLD40X125-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125-S
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×125 | 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 MALD40X125-S Is Used
Servo-Drive Indexing
Drives the oscillating tool head on a printed-circuit-board depaneling router, using the 528 N equal force to push and retract the cutting bit without stroke asymmetry.
Pouch Splicing Jaws
Actuates the dual sealing jaws on a vertical form-fill-seal packaging machine, where the twin rods resist torsional twist during the 125mm sealing cycle.
Rear-Cam Trip Mechanism
Operates a cam-actuated trip release on an assembly press, using the protruding rear rod to trigger a mechanical signal at full stroke.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125-S with MBLD40X125-S
To replace the MALD40X125-S with the MBLD40X125-S, confirm the 125mm stroke, G1/4 port, PT thread, M12x1.25 rod-end, and FA or LB mounting (there is no back cover or SDB option). Retain the -S magnet but plan to swap CS1-M / DS1-M sensors for CMSG / DMSG / EMSG equivalents. Size on the 528 N equal force: stepping down, the 32mm bore yields 346 N at 0.5 MPa; stepping up is not available as 40mm is the largest MALD bore.
Upgrade checklist
- ✓ Order the MBLD40X125-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 MBLD40X125-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X125-S FAQ
Yes, the MALD40X125-S is discontinued. The exact drop-in replacement is the MBLD40X125-S, which matches the 40mm bore, 125mm stroke, 528 N equal force, and G1/4 port. You must update your sensors: the MALD -S magnet uses CS1-M / DS1-M switches, while the MBLD uses CMSG / DMSG / EMSG switches.
Force is equal both ways because twin rods exit both ends, making the annulus area identical on the extend and retract sides. The exact ratings are 528 N push and 528 N pull at 0.5 MPa, 739 N push and 739 N pull at 0.7 MPa, and a maximum force of 108 kgf at 1.0 MPa.
