This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X30S 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 MALD40X30S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X30S 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 MBLD40X30S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X30S
The AirTAC MALD40X30S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal push and pull force of 528 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD40X30S, matching the 40 mm bore, 30 mm stroke, G1/4 port, and mounting.
This -S SKU includes a magnet for CS1-M or DS1-M reed switches; the MBLD upgrade uses CMSG, DMSG, or EMSG sensors. The MALD features threaded covers, while the MBLD uses a riveted rolling-packed body. Twin rods resist rotation and double the bearing load, allowing a rear rod to carry a cam or flag. It uses a fixed rubber bumper, not an adjustable cushion or lock.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X30S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X30S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X30S |
| Bore size | Ø40 mm |
| Stroke | 30 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 MBLD40X30S 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 MBLD40X30S matches these values.

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 MALD40X30S Is Used
PCB Reject Conveyor
Uses the equal 528N pull force and anti-rotation twin rods to sharply flick defective printed circuit boards off a high-speed SMT line without rotational drift.
Textile Beam Indexing
The rear rod carries a mechanical flag to trip a limit switch, sequencing the 30mm shift of heavy weaving beams while the front rod pushes the carriage.
Dual-End Pneumatic Clamp
Simultaneously clamps two sheet-metal panels from opposite sides using both rod ends, leveraging the fixed rubber bumper to soften the 739N impact at 0.7 MPa.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X30S with MBLD40X30S
Replace the MALD40X30S with the drop-in MBLD40X30S. Confirm the 40 mm bore, 30 mm stroke, M12x1.25 rod-end thread, G1/4 port, and FA or LB mounting (there is no back-cover or SDB code on this double-rod body). Because this -S SKU has a magnet, swap your CS1-M or DS1-M switches for CMSG, DMSG, or EMSG sensors. Size on the equal 528 N force at 0.5 MPa. To step down, the 32 mm bore provides 346 N each way; to step up, 40 mm is the largest MALD bore available. The 30 mm stroke is short, so side-load is minimal, but always guide the load to prevent rod binding.
Upgrade checklist
- ✓ Order the MBLD40X30S (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 MBLD40X30S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X30S FAQ
Yes, the MALD40X30S is discontinued. The exact drop-in replacement is the MBLD40X30S, offering the same 40 mm bore, 30 mm stroke, equal force, G1/4 port, and mounting. You must update your sensors: the MALD uses CS1-M or DS1-M switches, while the MBLD uses CMSG, DMSG, or EMSG.
Force is equal because the double-rod design means both sides of the piston see the same annulus area. The push and pull force is 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a maximum of 108 kgf at 1.0 MPa. The cylinder uses a fixed rubber bumper, not an adjustable cushion or a load-holding lock.
