This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD32X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD32X20S 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 MALD32X20S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD32X20S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø32mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD32X20S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD32X20S
The AirTAC MALD32X20S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal push and pull force of 346 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD32X20S, matching the 32 mm bore, 20 mm stroke, G1/8 port and mounting.
This -S variant has a magnet for CS1-M or DS1-M switches; the MBLD upgrade uses CMSG, DMSG or EMSG sensors. The MALD uses threaded covers, while the MBLD features a riveted rolling-packed body. It has a fixed rubber bumper and no back cover or SDB, mounting via the body, LB foot or FA flange.
Airtac MALD Aluminum Alloy Mini Cylinder MALD32X20S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD32X20S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD32X20S |
| Bore size | Ø32 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 500 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD32X20S carries the same ratings.
Output Force — Equal Both Ways (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD32X20S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD32X20S Is Used
PCB Router Z-Axis
Drives a dual-spindle PCB routing head. The twin 12 mm rods resist router torque, and the 346 N force at 0.5 MPa holds the cutting depth securely against board resistance.
Labeler Feed Drum
Advances a rotary label drum where a rear rod carries a cam. Equal 346 N force both ways ensures precise label web advancement and retraction without pressure imbalance.
Pneumatic Gripper Jaw
Actuates synchronized gripper jaws on an assembly pick-and-place. The fixed rubber bumper softens the 20 mm stroke end impact, protecting delicate electronic components.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD32X20S with MBLD32X20S
To replace the MALD32X20S, specify the MBLD32X20S and confirm the 32 mm bore, 20 mm stroke, M10x1.25 rod-end thread, G1/8 PT port, and FA/LB mounting. The -S magnet requires switching from CS1-M/DS1-M to CMSG/DMSG/EMSG switches. Size using the equal 346 N force at 0.5 MPa. To step down, the 25 mm bore gives 206 N; to step up, the 40 mm bore provides 528 N.
Upgrade checklist
- ✓ Order the MBLD32X20S (same bore/stroke/force)
- ✓ Force equal both ways (346 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 MBLD32X20S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD32X20S FAQ
Yes, the MALD32X20S is discontinued. The exact drop-in replacement is the MBLD32X20S, matching the 32 mm bore, 20 mm stroke, G1/8 port and mounting. You must update your sensor choice: the MALD -S magnet uses CS1-M/DS1-M switches, while the MBLD uses CMSG/DMSG/EMSG switches.
Force is equal both ways because a rod exits both ends, making the piston area an annulus on both sides. It provides 346 N push and 346 N pull at 0.5 MPa, 484 N each way at 0.7 MPa, and a maximum of 70 kgf at 1.0 MPa.
