This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X75-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 MALD40X75-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75-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 MBLD40X75-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75-S
The AirTAC MALD40X75-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding exactly 528 N of force each way at 0.5 MPa. The exact drop-in replacement is the MBLD40X75-S, matching the 40mm bore, 75mm stroke, G1/4 port, and mounting.
This -S SKU includes a magnet for position sensing. The original MALD uses CS1-M or DS1-M switches, while the MBLD upgrade uses CMSG, DMSG, or EMSG sensors. Unlike the threaded covers on this MALD, the MBLD features a riveted rolling-packed body. Twin rods prevent rod rotation and double the bearing load for guided slide applications.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X75-S |
| Bore size | Ø40 mm |
| Stroke | 75 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 MBLD40X75-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 MBLD40X75-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75-S Is Used
PCB Edge-Deburring Fixture
Twin rods resist rotational drift while routing PCB panel edges, applying 528 N of equal force to maintain precise cutting geometry without yaw.
Textile Calender Cam
The rear rod carries a cam to actuate a fabric guide valve, using the 75mm stroke to shift the calender roller precisely during high-speed weaving.
Bottle Capping Yoke
Dual rods distribute the 108 kgf maximum load across two bearings, preventing cap distortion as the capping head descends onto plastic bottle threads.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75-S with MBLD40X75-S
To replace this MALD40X75-S with the MBLD40X75-S, confirm the 40mm bore, 75mm stroke, G1/4 port, M12x1.25 rod thread, and FA or LB mounting (there is no back-cover or SDB option). Size your system on the 528 N equal push and pull force at 0.5 MPa. If you need less force, step down to the 32mm bore which provides 346 N each way at 0.5 MPa. If you need more force, this 40mm bore is the largest available, delivering a maximum of 108 kgf at 1.0 MPa. The stroke is under the 500mm limit, so no side-load guide concerns apply here.
Upgrade checklist
- ✓ Order the MBLD40X75-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 MBLD40X75-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X75-S FAQ
Yes, the MALD40X75-S is discontinued. The exact drop-in replacement is the MBLD40X75-S, which matches the 40mm bore, 75mm stroke, 528 N force, G1/4 port, and mounting. You will only need to update your position sensors, as the MBLD uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
The bore is 40mm with a G1/4 port. Because it is a double-rod cylinder, the push and pull forces are equal: 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 for end-of-stroke impact absorption, not an adjustable cushion.
