This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X225S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X225S 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 MALD20X225S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X225S 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 MBLD20X225S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X225S
The AirTAC MALD20X225S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, so push and pull forces are equal at 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X225S, matching the 20 mm bore, 225 mm stroke, G1/8 port, and mounting.
This -S SKU includes a magnet for position sensing. The original MALD uses CS1-M or DS1-M switches, while the MBLD upgrade requires CMSG, DMSG, or EMSG sensors. Unlike the threaded covers on this MALD, the MBLD features a riveted rolling-packed body. Twin rods double the bearing surface to resist rotation, and the fixed rubber bumper absorbs end-of-stroke impact without acting as a load lock.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X225S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X225S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X225S |
| Bore size | Ø20 mm |
| Stroke | 225 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 MBLD20X225S 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 MBLD20X225S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X225S

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 MALD20X225S Is Used
PCB Edge Conveyor Stopper
Uses the 132 N equal force to halt populated circuit boards on an assembly line without deflecting the workpiece, while the rear rod carries a cam for a downstream sensor.
Pick-and-Place Y-Axis Slide
Twin rods resist rotational twist during horizontal travel, maintaining gripper alignment over the 225 mm stroke for small electronic component placement.
Small Part Ejector Gate
The double-rod geometry pushes a diverter gate on the forward stroke and pulls it back evenly, preventing binding in compact machined-part sorting chutes.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X225S with MBLD20X225S
To replace the MALD20X225S with the MBLD20X225S, confirm the 20 mm bore, 225 mm stroke, M8x1.25 rod-end thread, G1/8 port, and FA or LB mounting. There is no back cover or SDB option. Size your application on the 132 N equal force both ways. If you need less force, step down to the neighbouring 16 mm bore (if available) or similar mini series; if you need more, step up to the 25 mm bore, which provides 206 N at 0.5 MPa. At 225 mm stroke, guide the load to prevent rod side-load and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD20X225S (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 MBLD20X225S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X225S FAQ
Yes, the MALD20X225S is discontinued. The exact drop-in replacement is the MBLD20X225S, which matches the 20 mm bore, 225 mm stroke, G1/8 port, and equal force. You will need to update your position sensors from the older CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
Because it is a double-rod cylinder, the push and pull forces are equal: 132 N at 0.5 MPa and 185 N at 0.7 MPa, with a maximum force of 27 kgf at 1.0 MPa. It uses a fixed rubber bumper at end-of-stroke, not an adjustable cushion, and it will not hold a load on air loss.
