This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X40S 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 MALD20X40S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X40S 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 MBLD20X40S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X40S
The AirTAC MALD20X40S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding exactly 132 N of equal force both ways at 0.5 MPa. The exact drop-in replacement is the MBLD20X40S, matching the 20 mm bore, 40 mm stroke, G1/8 port, and mounting.
This -S SKU uses a CS1-M / DS1-M magnet sensor, whereas the MBLD upgrade uses CMSG / DMSG / EMSG switches. The original MALD features threaded covers, while the MBLD uses a riveted rolling-packed body. It has a fixed rubber bumper and no back cover or SDB, mounting via the body, FA, or LB.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X40S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X40S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X40S |
| Bore size | Ø20 mm |
| Stroke | 40 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 MBLD20X40S 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 MBLD20X40S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X40S
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 20 | Bore size in mm (20/25/32/40). |

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 MALD20X40S Is Used
PCB Depaneling Saw
Provides 132 N of equal push and pull to grip and sever populated circuit boards without rotational drift on the 40 mm stroke.
Label Applicator Nip
Drives a dual-sided nip roll at 132 N force, using the rear rod to carry a cam for timing the label feed cut.
Pick-and-Place Fork
Uses twin rods to resist torsion on a 40 mm lift, ensuring the rear rod can safely host a flag for CS1-M position sensing.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X40S with MBLD20X40S
Replace this MALD20X40S with the MBLD20X40S. Confirm the 20 mm bore, 40 mm stroke, G1/8 port, and M8x1.25 rod-end thread. The -S magnet means you must change from CS1-M / DS1-M to CMSG / DMSG / EMSG sensors. Mounting is FA or LB only; there is no back-cover or SDB code. Size on the 132 N equal force. To step down, no smaller bore exists. To step up, the 25 mm bore offers 206 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBLD20X40S (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 MBLD20X40S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X40S FAQ
Yes, the MALD20X40S is discontinued. The exact drop-in replacement is the MBLD20X40S, which matches the 20 mm bore, 40 mm stroke, G1/8 port, and 132 N equal force. You must update your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
Force is equal both ways because a rod exits both ends, making the annulus area identical on each side. The ratings are 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, not an adjustable cushion.
