This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X20S 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 MALD25X20S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø25mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD25X20S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20S
The AirTAC MALD25X20S is a discontinued double-acting, double-rod mini cylinder. A Ø10 mm rod exits both ends, yielding exactly 206 N of force in both push and pull directions at 0.5 MPa. The direct drop-in replacement is the MBLD25X20S, matching the 25 mm bore, 20 mm stroke, and G1/8 port.
This SKU includes the -S magnet for position sensing. The legacy MALD uses threaded covers and CS1-M / DS1-M switches, whereas the MBLD upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. It uses a fixed rubber bumper, has no back cover or SDB option, and mounts via the body, FA flange, or LB foot.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X20S |
| Bore size | Ø25 mm |
| Stroke | 20 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 MBLD25X20S carries the same ratings.
Output Force — Equal Both Ways (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | 289 N |
| Max (@1.0 MPa) | 42 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD25X20S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20S Is Used
PCB Depaneling Saw
Drives a guided cutting blade on a depaneling router. The twin rods prevent rotational drift during the 20 mm plunge, ensuring a clean, vibration-free cut on dense FR4 fiberglass boards.
Pneumatic Escapement
Acts as a synchronized parts diverter in a bowl feeder outlet. The equal 206 N force both ways ensures crisp, symmetric part release without requiring pressure compensation.
Label Wipe-down Brush
Mounts a rear-facing brush on the secondary rod to wipe cartons as they pass. The fixed rubber bumper absorbs the 20 mm stroke impact without crushing the corrugated packaging.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20S with MBLD25X20S
To replace your MALD25X20S with the MBLD25X20S, confirm the 25 mm bore, 20 mm stroke, G1/8 PT port, and FA/LB mounting. Plan to swap your CS1-M / DS1-M sensors for the CMSG / DMSG / EMSG family, as the new body uses a riveted rolling-packed design instead of threaded covers. Size using the equal 206 N force both ways at 0.5 MPa. If you need to step down, the 20 mm bore provides 132 N; to step up, the 32 mm bore yields 346 N.
Upgrade checklist
- ✓ Order the MBLD25X20S (same bore/stroke/force)
- ✓ Force equal both ways (206 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 MBLD25X20S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X20S FAQ
Yes, the MALD25X20S is discontinued. The exact drop-in replacement is the MBLD25X20S. It matches the 25 mm bore, 20 mm stroke, G1/8 port, and equal 206 N both-ways force. You will need to upgrade your switches from the legacy CS1-M / DS1-M to the CMSG / DMSG / EMSG sensor family.
Because a rod exits both ends, the piston sees the same annular area on both sides, making push and pull force equal. The ratings are 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion.
