This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X100S 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 MALD20X100S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100S 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 MBLD20X100S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100S
The AirTAC MALD20X100S is a discontinued double-acting, double-rod miniature cylinder. A rod exits both ends of the 20mm bore, yielding equal force in both directions (132 N each way at 0.5 MPa). The exact drop-in replacement is the MBLD20X100S, matching the 100mm stroke, G1/8 port, and mounting footprint.
This twin-rod design doubles the bearing area to resist side loads and prevents rod rotation without external guides. The MALD features threaded covers and a fixed rubber bumper. Its -S magnet works with legacy CS1-M / DS1-M switches, whereas the MBLD upgrade uses a riveted rolling-packed body and modern CMSG / DMSG / EMSG sensors.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X100S |
| Bore size | Ø20 mm |
| Stroke | 100 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 MBLD20X100S 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 MBLD20X100S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100S Is Used
PCB Edge Guiding
Uses the 132N equal force to push and pull a PCB edge guide simultaneously, preventing rotation during conveyor transfer without needing external linear bearings.
Dual Pick-and-Place
Mounts a suction cup on the front rod and a cam flag on the rear rod, allowing a compact 100mm stroke pick-and-place to trigger a legacy CS1-M sensor for part confirmation.
Label Applicator Brake
Applies equal tensioning force in both directions on a label web roller, relying on the fixed rubber bumper to soften the 100mm stroke ends without adjustable cushioning.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100S with MBLD20X100S
To replace the MALD20X100S, specify the MBLD20X100S. Confirm the 20mm bore, 100mm stroke, G1/8 port, PT thread form, and FA or LB mounting (there is no back cover or SDB option). Size using the equal force: 132 N at 0.5 MPa. If you need less force, step down to the 20mm bore's nearest neighbor is unavailable as it is the smallest size, so step up to bore 25, which provides 206 N at 0.5 MPa. At 100mm stroke, side loading is moderate, but ensure the twin rods carry the load axially to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLD20X100S (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 MBLD20X100S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100S FAQ
Yes, the MALD20X100S is discontinued. The exact drop-in replacement is the MBLD20X100S, which matches the 20mm bore, 100mm stroke, G1/8 port, and equal force. You will only need to update your sensors from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG series.
Because a rod exits both ends, the piston sees the same annulus area on both sides, making push and pull force identical. The ratings are: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. The cylinder uses a fixed rubber bumper, not an adjustable cushion.
