This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X80-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X80-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 MALD40X80-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80-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 MBLD40X80-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80-S
The AirTAC MALD40X80-S is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends of the 40mm bore, yielding exactly 528 N of force each way at 0.5 MPa. The exact drop-in replacement is the MBLD40X80-S, matching the 80mm stroke, G1/4 port, and mounting footprint.
This -S SKU includes a magnet for CS1-M or DS1-M reed switches. The MBLD upgrade shifts to CMSG/DMSG/EMSG sensors and swaps the original threaded covers for a riveted rolling-packed body. Twin rods double the bearing area and prevent rod rotation, letting you mount a cam or flag on the rear extension without adding an external guide.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X80-S |
| Bore size | Ø40 mm |
| Stroke | 80 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 MBLD40X80-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 MBLD40X80-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80-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 MALD40X80-S Is Used
PCB Edge Deburring
Drives a dual-sided deburring blade on a printed circuit board line, using the 528 N equal force to cleanly shear copper burrs without deflecting the stage.
Textile Beam Indexing
Shifts heavy warp beams between creels in a textile mill, relying on the twin 16mm rods to prevent binding under the long, off-center load.
Pallet Transfer Cam
Uses the rear rod extension to trip a mechanical cam on a packaging conveyor, eliminating the need for a separate position sensor.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80-S with MBLD40X80-S
Replace this MALD40X80-S directly with the MBLD40X80-S. Confirm the 40mm bore, 80mm stroke, M12x1.25 rod-end thread, PT port form, and FA or LB mounting. Because it lacks a back-cover code and SDB, you mount it on the body, foot, or flange. The -S magnet means you must upgrade your CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
Size on the 528 N equal force both ways. If 528 N is too much, step down to the 32mm bore delivering 346 N at 0.5 MPa. If you need more push, note that 40mm is the largest available MALD bore, so 528 N is your maximum capacity in this frame.
Upgrade checklist
- ✓ Order the MBLD40X80-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 MBLD40X80-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X80-S FAQ
Yes, the MALD40X80-S is discontinued. The exact drop-in replacement is the MBLD40X80-S, which matches the 40mm bore, 80mm stroke, 528 N force, and G1/4 port. You will need to swap your CS1-M/DS1-M sensors to the CMSG/DMSG/EMSG family.
It provides 528 N push and 528 N pull at 0.5 MPa, 739 N both ways at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion, so it cannot hold a load on air loss.
