This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X75-S 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 MALD20X75-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X75-S 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 MBLD20X75-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X75-S
The AirTAC MALD20X75-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal force both ways at 132 N (0.5 MPa). The exact drop-in replacement is the MBLD20X75-S, matching the 20 mm bore, 75 mm stroke, G1/8 port, and mounting.
This -S variant uses a CS1-M / DS1-M magnet switch in a threaded-cover body, whereas the MBLD upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. The twin-rod layout resists rotation and doubles the bearing area, while the rear rod can carry a flag or cam. It uses a fixed rubber bumper, has no back cover or SDB, and mounts via the body, FA flange, or LB foot.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X75-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X75-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X75-S |
| Bore size | Ø20 mm |
| Stroke | 75 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 MBLD20X75-S 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 MBLD20X75-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X75-S Is Used
PCB Edge-Guiding
Uses the 132N equal force to push a guide rail against printed circuit boards on a conveyor, with the rear rod carrying a cam to trigger a downstream pick-and-place.
Textile Yarn Tensioner
Anti-rotation twin rods keep a ceramic eyelet perfectly aligned, applying constant 0.5MPa pull on synthetic yarn lines without twisting the tooling.
Small-Part Ejector
Double-rod action ejects stamped micro-connectors from a die, using the fixed rubber bumper to soften end impact while the equal pull retracts the part.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X75-S with MBLD20X75-S
To replace the MALD20X75-S, specify the MBLD20X75-S. Confirm the 20 mm bore, 75 mm stroke, G1/8 port, M8x1.25 rod-end thread, and FA/LB mounting. Because it lacks a back cover and SDB, you mount directly on the body. Size using the equal-both-ways force: 132 N at 0.5 MPa. If you need less force, step down does not exist as 20 mm is the smallest bore. To step up, the 25 mm bore provides 206 N at 0.5 MPa. At 75 mm stroke, side-load is minimal, but always ensure the twin rods guide the load to prevent binding.
Upgrade checklist
- ✓ Order the MBLD20X75-S (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 MBLD20X75-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X75-S FAQ
Yes, the MALD20X75-S is discontinued. The exact drop-in replacement is the MBLD20X75-S, matching the 20mm bore, 75mm stroke, G1/8 port, and mounting. You must upgrade your sensors: the MALD -S uses CS1-M / DS1-M switches, while the MBLD uses CMSG / DMSG / EMSG.
Force is equal both ways because a rod exits both ends, making the annulus area identical on the push and pull sides. The ratings are: 132N at 0.5MPa, 185N at 0.7MPa, and a maximum of 27kgf at 1.0MPa.
