This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X15S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X15S 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 MALD20X15S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø20mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD20X15S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15S
The AirTAC MALD20X15S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering equal force in both directions at 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X15S, matching the 20mm bore, 15mm stroke, G1/8 port, and mounting.
This twin-rod design provides anti-rotation guidance and allows a rear flag for position sensing. The original -S magnet uses CS1-M or DS1-M switches, while the MBLD upgrade uses CMSG, DMSG, or EMSG sensors with a riveted rolling-packed body replacing the threaded covers.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X15S |
| Bore size | Ø20 mm |
| Stroke | 15 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 300 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD20X15S carries the same ratings.
Output Force — Equal Both Ways (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | 185 N |
| Max (@1.0 MPa) | 27 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD20X15S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15S Is Used
PCB Depaneling Saw
Guides the circular saw blade carriage on an inline PCB router. The twin rods prevent chassis rotation during the 15mm cutting plunge, utilizing the 132N equal force for stable, chatter-free slicing.
Pneumatic Ejector Gate
Actuates a short-stroke reject gate on a conveyor for small plastic housings. The rear rod carries a cam to confirm ejection via a CS1-M sensor, ensuring the 15mm travel fully clears the product path.
Micro-Gripper Slide
Drives a synchronized pick-and-place gripper for electronic chip sorting. The double-rod symmetry ensures the jaws close evenly without twisting, maintaining alignment under the 185N force at 0.7 MPa.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15S with MBLD20X15S
Replace the MALD20X15S with the MBLD20X15S. Confirm the 20mm bore, 15mm stroke, M8x1.25 rod-end thread, and G1/8 port. The double-rod design mounts via FA flange or LB foot, as there is no back cover or SDB option. Size your system on the 132 N equal force. If you need less force, step down does not exist as 20mm is the smallest, but you can step up to the 25mm bore for 206 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X15S (same bore/stroke/force)
- ✓ Force equal both ways (132 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 MBLD20X15S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X15S FAQ
Yes, the MALD20X15S is discontinued. The exact drop-in replacement is the MBLD20X15S, which matches the 20mm bore, 15mm stroke, G1/8 port, and mounting. You must upgrade your sensors from the old CS1-M or DS1-M switches to the CMSG, DMSG, or EMSG family.
The MALD20X15S is a double-rod cylinder, so the push and pull forces are equal: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. It uses a fixed rubber bumper at the end of stroke for impact softening; it does not have an adjustable cushion, and the bumper is not a lock.
