This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X300-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X300-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 MALD25X300-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300-S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø25mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD25X300-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300-S
The AirTAC MALD25X300-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 25 mm bore, yielding equal force both ways at 206 N (0.5 MPa). The exact drop-in replacement is the MBLD25X300-S, matching the 300 mm stroke, G1/8 port, and 42 kgf maximum force.
This SKU includes the -S magnet for legacy CS1-M or DS1-M reed switches; the MBLD upgrade shifts to CMSG, DMSG, or EMSG sensors. The original MALD uses threaded covers, whereas the MBLD features a riveted rolling-packed body. Both lack a back cover or SDB, mounting directly via the body, FA flange, or LB foot.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X300-S |
| Bore size | Ø25 mm |
| Stroke | 300 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 MBLD25X300-S carries the same ratings.
Output Force — Equal Both Ways (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | 289 N |
| Max (@1.0 MPa) | 42 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD25X300-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300-S

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 MALD25X300-S Is Used
PCB Depaneling Saw
Drives a circular blade on a 300 mm cut stroke. The twin rods prevent blade yaw, while 206 N of equal force ensures consistent feed rate on both the cutting and return strokes.
Textile Loom Tenter
Stretches fabric via a cam on the rear rod. The double-rod design provides anti-rotation stability, and the -S magnet triggers a DS1-M switch to confirm the 300 mm clamp position.
Bottle Sorting Diverter
Mounts dual deflecting fingers on opposite rod ends to simultaneously gate two lanes. The 289 N force at 0.7 MPa easily pushes filled glass containers without torsional twist.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300-S with MBLD25X300-S
To replace the MALD25X300-S, order the MBLD25X300-S. Confirm the 25 mm bore, 300 mm stroke, PT G1/8 port, M10x1.25 rod-end thread, and LB/FA mounting. Retain the -S magnet, but note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG.
Size on the equal 206 N force. If you need less power, step down to the 20 mm bore (132 N at 0.5 MPa). If you need more, step up to the 32 mm bore (346 N at 0.5 MPa). At 300 mm stroke, twin rods help resist side-load sagging, but ensure external guide rails carry heavy tooling to protect the 10 mm chrome rods.
Upgrade checklist
- ✓ Order the MBLD25X300-S (same bore/stroke/force)
- ✓ Force equal both ways (206 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 MBLD25X300-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300-S FAQ
Yes, the MALD25X300-S is discontinued. The exact drop-in replacement is the MBLD25X300-S, matching the 25 mm bore, 300 mm stroke, G1/8 port, and 42 kgf max force. You will need to update your sensors, as the MBLD uses CMSG/DMSG/EMSG switches instead of the old CS1-M/DS1-M.
Force is equal because both sides of the piston have the same annulus area due to the double-rod design. Push and pull are both 206 N at 0.5 MPa, both 289 N at 0.7 MPa, and the maximum force is 42 kgf at 1.0 MPa. The cylinder uses a fixed rubber bumper, not an adjustable cushion.
