This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X300-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X300-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 MALD20X300-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300-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 MBLD20X300-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300-S
The AirTAC MALD20X300-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 20 mm bore, yielding equal force in both directions (132 N each way at 0.5 MPa). The direct drop-in replacement is the MBLD20X300-S, matching the 300 mm stroke, G1/8 port, and mounting footprint.
This -S SKU includes a magnet for position sensing. The legacy MALD uses CS1-M / DS1-M reed switches, whereas the MBLD upgrade uses CMSG / DMSG / EMSG sensors. The original features threaded covers and a fixed rubber bumper, while the newer MBLD uses a riveted rolling-packed body. No back cover or SDB option exists on this double-rod body.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X300-S |
| Bore size | Ø20 mm |
| Stroke | 300 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 MBLD20X300-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 MBLD20X300-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300-S Is Used
PCB Depaneling Saw
Drives a synchronized blade carriage on a depaneling router. The twin rods prevent rotation during the 300 mm cut, while the 132 N force at 0.5 MPa securely holds the cutting head without deflection.
Loom Weft Feeder
Actuates a weft yarn guide in a textile loom. The rear rod mounts a cam to trigger a legacy CS1-M reed switch, using the full 300 mm travel to lay wide fabric patterns precisely.
Label Dispenser Head
Advances a peel plate on an industrial labeling machine. The equal push and pull force ensures smooth label web tensioning across the long stroke, aided by the fixed rubber bumper absorbing rapid end impacts.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300-S with MBLD20X300-S
To replace the MALD20X300-S, specify the MBLD20X300-S. Confirm the 20 mm bore, 300 mm stroke, M8x1.25 rod-end thread, G1/8 PT port, and FA or LB mounting. Because the -S magnet is present, plan to swap your CS1-M / DS1-M switches for CMSG / DMSG / EMSG sensors. Size using the equal-both-ways force: if you need less power, step down to the 20 mm bore (132 N at 0.5 MPa is the smallest available); if you need more, step up to the 25 mm bore (206 N at 0.5 MPa).
At 300 mm stroke on an 8 mm rod, side loading is a critical wear factor. Ensure external guide rails carry the load to prevent rod binding and premature seal failure.
Upgrade checklist
- ✓ Order the MBLD20X300-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 MBLD20X300-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X300-S FAQ
Yes, the MALD20X300-S is discontinued. The exact drop-in replacement is the MBLD20X300-S, which matches the 20 mm bore, 300 mm stroke, G1/8 port, and mounting. You must update your sensors: the MALD -S magnet used CS1-M / DS1-M switches, while the MBLD uses CMSG / DMSG / EMSG switches.
Because a rod exits both ends, the piston sees the same annulus area on both faces. The force is equal both ways: 132 N push and 132 N pull at 0.5 MPa, 185 N push and 185 N pull at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa.
