This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X300 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X300 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
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300 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, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300
The AirTAC MALD25X300 is a discontinued double-acting, double-rod mini cylinder delivering an equal 206 N of push and pull force at 0.5 MPa. Because a rod exits both ends, the annulus area is identical on each side, making it ideal for symmetrical work. The exact drop-in replacement is the MBLD25X300, matching the 25 mm bore, 300 mm stroke, G1/8 port, and mounting footprint.
This SKU has no magnet and cannot accept a position sensor. The original MALD used threaded covers and a CS1-M / DS1-M sensor slot, whereas the MBLD upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG switches. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable cushion. At 300 mm, the stroke hits the maximum standard limit for this bore, meaning the extended rod is highly susceptible to side-load bending if the load is not guided.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X300 |
| 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 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 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300 Is Used
PCB Shuttle Transfer
Drives a dual-sided shuttle carriage in a PCB handling machine. The twin rods provide anti-rotation stability across the full 300 mm travel, while the equal 206 N force ensures consistent forward and reverse indexing.
Gripper Cam Actuation
Moves a rear-mounted cam on a packaging line gripper. The extending rear rod actuates a secondary mechanism, using the fixed rubber bumper to soften the end impact without needing adjustable cushions.
Textile Web Guiding
Tensions and guides fabric webs in a textile machine. The double-rod geometry doubles the bearing surface, resisting deflection on the long 300 mm stroke while maintaining 289 N of force at 0.7 MPa.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300 with MBLD25X300
To replace the MALD25X300 with the MBLD25X300, confirm the 25 mm bore, 300 mm stroke, G1/8 PT port, and M10x1.25 rod-end thread. Mount directly on the body, or use an FA flange or LB foot; there is no back-cover or SDB option on this double-rod series. Because this SKU lacks the -S magnet, it cannot support a sensor—if sensing is required, you must move to an MBLD25X300S and use CMSG / DMSG / EMSG switches instead of the legacy CS1-M / DS1-M.
Size the replacement using the equal-both-ways force: 206 N at 0.5 MPa. If you need less force, step down to the 20 mm bore (132 N each way). If you need more power, step up to the 32 mm bore (346 N each way). Since this 300 mm stroke is the maximum standard length for a 25 mm bore, you must use an external guide rail to prevent rod bending and premature seal wear under side loads.
Upgrade checklist
- ✓ Order the MBLD25X300 (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 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X300 FAQ
Yes, the MALD25X300 is discontinued. The exact drop-in replacement is the MBLD25X300, matching the 25 mm bore, 300 mm stroke, G1/8 port, and mounting dimensions. The MBLD upgrades the construction with a riveted rolling-packed body instead of threaded covers.
This SKU has no -S magnet and cannot take a position sensor. The force is equal both ways: 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. It uses a fixed rubber bumper rather than an adjustable cushion.
