This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X50-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X50-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 MALD20X50-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50-S 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 MBLD20X50-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50-S
The AirTAC MALD20X50-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering equal push and pull force of 132 N at 0.5 MPa. The exact drop-in replacement is the MBLD20X50-S, matching the 20 mm bore, 50 mm stroke, G1/8 port, and mounting.
The twin-rod design resists rotation and doubles the bearing load for guided slides, while the rear rod can carry a flag or cam. This -S SKU uses older CS1-M / DS1-M switches; the MBLD replacement upgrades to CMSG / DMSG / EMSG sensors and a riveted rolling-packed body instead of threaded covers.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X50-S |
| Bore size | Ø20 mm |
| Stroke | 50 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 MBLD20X50-S 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 MBLD20X50-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50-S
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 20 | Bore size in mm (20/25/32/40). |
| ×50 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLD uses CMSG/DMSG/EMSG). |
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 MALD20X50-S Is Used
PCB Edge Guiding
Twin rods prevent rotation during thin PCB edge gripping, delivering precise 132 N equal force for delicate board handling.
Pick-and-Place Cam
The rear rod carries a cam flag to trigger legacy CS1-M sensors, timing 50 mm travel for small electronic component placement.
Label Dispenser Slide
Doubles the bearing surface to resist side-loading on a guided label applicator head, maintaining stable push and pull motion.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50-S with MBLD20X50-S
Replace this MALD20X50-S with the exact drop-in MBLD20X50-S. Confirm the 20 mm bore, 50 mm stroke, G1/8 port, and FA or LB mounting (there is no back cover or SDB option). The -S magnet requires a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. Size on the equal 132 N force at 0.5 MPa. If you need less force, the next size down is bore 12 (confirm from datasheet). If you need more force, step up to the 25 mm bore, which provides 206 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X50-S (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 MBLD20X50-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X50-S FAQ
Yes, the MALD20X50-S is discontinued. The exact drop-in replacement is the MBLD20X50-S, which matches the 20 mm bore, 50 mm stroke, G1/8 port, and mounting. You must upgrade the -S magnet sensor from CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
The double-rod design means push and pull force 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 for end-of-stroke impact absorption; it has no adjustable cushion and will not hold a load on air loss.
