This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X175 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X175 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 MALD20X175
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175 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 MBLD20X175, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175
The AirTAC MALD20X175 is a discontinued double-acting, double-rod mini cylinder. Because rods exit both ends, the annulus area is identical on both sides, giving equal push and pull force of 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X175, matching the 20 mm bore, 175 mm stroke, G1/8 port, and mounting.
This SKU has no magnet and cannot accept a position sensor. The original MALD uses threaded covers, while the MBLD upgrade features a riveted rolling-packed body. It uses a fixed rubber bumper for end-of-stroke damping, and the twin rods provide high anti-rotation resistance and double the bearing load capacity for guided sliding tasks.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X175 |
| Bore size | Ø20 mm |
| Stroke | 175 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 MBLD20X175 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 MBLD20X175 matches these values.

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 MALD20X175 Is Used
PCB Edge Guiding
Drives a guided edge-rail on a PCB conveyor. The twin rods prevent yaw during the 175 mm traverse, keeping the 132 N clamping force perfectly aligned without twisting.
Dual-End Tooling Shuttle
Uses the rear rod extension to trigger a mechanical cam on a small assembly station. The equal force both ways ensures smooth part handoff at 0.5 MPa.
Label Applicator Platen
Pushes a label platen in a packaging line. The fixed rubber bumper absorbs the end impact, while the double-rod design resists rotational drift during high-speed cycling.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175 with MBLD20X175
To replace the MALD20X175, specify the MBLD20X175. Confirm the 20 mm bore, 175 mm stroke, G1/8 port, and PT thread form. Mount directly on the body or via FA/LB brackets—there is no back cover or SDB option. This non-magnet SKU cannot take a sensor; if you need position detection, move to an MBLD-S model which uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
Size on the equal 132 N force. If you need less power, step down is not possible as 20 mm is the smallest bore. To step up, the 25 mm bore provides 206 N at 0.5 MPa. At 175 mm stroke, support the load externally to prevent rod side-load and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD20X175 (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 MBLD20X175 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175 FAQ
Yes, the MALD20X175 is discontinued. The exact drop-in replacement is the MBLD20X175, matching the 20 mm bore, 175 mm stroke, G1/8 port, and mounting. The MBLD upgrades the construction with a riveted rolling-packed body instead of threaded covers.
Force is equal both ways due to the double-rod design: 132 N push and pull 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 damping, not an adjustable cushion. This SKU lacks a magnet, so it cannot accept a position sensor.
