This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD20X175, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct 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 direct 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 direct 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.
