This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X50-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X50-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 MALD40X50-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X50-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 MBLD40X50-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X50-S
The AirTAC MALD40X50-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 40 mm bore, yielding equal force both ways at 528 N at 0.5 MPa. The exact drop-in replacement is the MBLD40X50-S, matching the 50 mm stroke, G1/4 port, and mounting.
This unit features a fixed rubber bumper and threaded covers, whereas the MBLD replacement uses a riveted rolling-packed body. The -S magnet on this MALD works with CS1-M / DS1-M switches; the MBLD upgrades to CMSG / DMSG / EMSG sensors. Twin 16 mm hard-chrome rods resist rotation and double the bearing load for guided sliding.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X50-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X50-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X50-S |
| Bore size | Ø40 mm |
| Stroke | 50 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 MBLD40X50-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 MBLD40X50-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X50-S Is Used
PCB Edge Deburring
Drives a dual-sided deburring blade on a printed circuit board line. The twin 16 mm rods prevent yaw during rapid reversals, while 528 N of equal force ensures consistent cutting pressure on both the push and pull strokes.
Textile Loom Beam Shift
Transfers heavy warp beams between creels. The rear rod carries a cam to trigger a pneumatic valve, using the 739 N force at 0.7 MPa to shift the load without requiring a separate external actuator.
Packaging Lid Press
Seals carton lids on a packaging conveyor. The fixed rubber bumper absorbs the 50 mm stroke end-impact without bouncing, while the double-rod geometry keeps the press plate perfectly parallel to the carton.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X50-S with MBLD40X50-S
To replace the MALD40X50-S, install the MBLD40X50-S. Confirm the 40 mm bore, 50 mm stroke, G1/4 port, PT thread, and FA or LB mounting. Note that MALD has no back cover or SDB; mount on the body. The -S magnet requires swapping your CS1-M / DS1-M switches to CMSG / DMSG / EMSG. Size using the equal force: this bore gives 528 N each way at 0.5 MPa. If you need less force, step down to the 32 mm bore (346 N); if you need more, this is the largest standard MALD size.
Upgrade checklist
- ✓ Order the MBLD40X50-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 MBLD40X50-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X50-S FAQ
Yes, the MALD40X50-S is discontinued. The exact drop-in replacement is the MBLD40X50-S, which matches the 40 mm bore, 50 mm stroke, G1/4 port, and mounting. You will need to update your sensors, as the MALD uses CS1-M / DS1-M switches while the MBLD uses CMSG / DMSG / EMSG.
Force is equal both ways because the twin rods create an identical annulus area on both sides of the piston. The 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.
