This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X100-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 MALD40X100-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X100-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 MBLD40X100-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X100-S
The AirTAC MALD40X100-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering an equal 528 N of push and pull force at 0.5 MPa. The exact drop-in replacement is the MBLD40X100-S, matching the 40 mm bore, 100 mm stroke, G1/4 port, and mounting.
This twin-rod design doubles the bearing area to resist side loads and prevent rotation, allowing a rear rod to carry a secondary tool or flag. The original MALD uses threaded covers and a CS1-M / DS1-M magnet switch, whereas the MBLD upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X100-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X100-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X100-S |
| Bore size | Ø40 mm |
| Stroke | 100 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 MBLD40X100-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 MBLD40X100-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X100-S

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 MALD40X100-S Is Used
PCB Depaneling Saw
Drives a circular blade with equal 528 N force in both directions, using the twin rods to keep the cut perfectly straight and resist rotational yaw during the return stroke.
Textile Loom Beam Index
Shifts heavy warp beams using the 739 N force at 0.7 MPa, relying on the dual M12x1.25 rods to prevent binding and maintain precise alignment across the 100 mm travel.
Pallet Transfer Rejector
Pushes faulty cartons off a conveyor line while the rear rod simultaneously triggers a mechanical flag, using the fixed rubber bumper to soften the 100 mm stroke impact without needing a lock.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X100-S with MBLD40X100-S
To replace the MALD40X100-S, specify the MBLD40X100-S and confirm the 40 mm bore, 100 mm stroke, G1/4 port, and M12x1.25 rod thread. Mount directly on the body, or use an LB foot or FA flange, as there is no back-cover or SDB option. Because the -S magnet is present, upgrade your sensing from CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
Size strictly on the equal 528 N force at 0.5 MPa (739 N at 0.7 MPa). If you need less force, step down to the 32 mm bore providing 346 N each way. If you need more, note that 40 mm is the largest MALD bore, so exceeding 108 kgf at 1.0 MPa requires a different cylinder family.
Upgrade checklist
- ✓ Order the MBLD40X100-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 MBLD40X100-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X100-S FAQ
Yes, the MALD40X100-S is discontinued. The exact drop-in replacement is the MBLD40X100-S, which matches the 40 mm bore, 100 mm stroke, G1/4 port, and equal force. You will need to change your sensors from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG switches.
Yes, because the double-rod design has the same annulus area on both sides, push and pull forces are equal. 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. It uses a fixed rubber bumper, not an adjustable cushion.
