This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X500 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X500 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 MALD25X500
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500 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 MBLD25X500, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500
The AirTAC MALD25X500 is a discontinued double-acting, double-rod mini cylinder. Because a rod exits both ends, the annulus area is identical on each side, giving equal force both ways at 206 N (0.5 MPa). The exact drop-in replacement is the MBLD25X500, matching the 25 mm bore, 500 mm stroke, G1/8 port, and mounting.
This 500 mm stroke exceeds the 300 mm standard limit for a 25 mm bore, making it a non-standard, made-to-order item. The twin 10 mm carbon-steel rods resist rotation and double the bearing load, though at 500 mm you must guide the load to prevent rod sag. This SKU lacks the -S magnet, so it cannot take a position sensor. The original MALD uses threaded covers and a fixed rubber bumper, while the MBLD upgrade features a riveted rolling-packed body.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X500 |
| Bore size | Ø25 mm |
| Stroke | 500 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 MBLD25X500 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 MBLD25X500 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500 Is Used
PCB Edge Conveyor Tracking
Drives a long-travel 500 mm sync belt slide for PCB panel routing. The twin rods prevent yaw during rapid 206 N transfer shifts, keeping electronic assemblies aligned without rotation.
Textile Beam Indexing
Indexes heavy fabric beams across a 500 mm span. The double-rod geometry provides balanced 206 N push and pull, maintaining stable tension without uneven rod deflection on long strokes.
Dual-Station Pick and Place
Moves a rear-mounted tooling flag between two machining stations. The rear rod acts as a mechanical sync track, while the fixed rubber bumper absorbs end-of-stroke impact at 0.5 MPa.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500 with MBLD25X500
To replace this MALD25X500, order the MBLD25X500. Confirm the 25 mm bore, 500 mm non-standard stroke, G1/8 PT port, and M10x1.25 rod-end thread. Mount via the body or LB/FA brackets, as there is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a sensor; if you need position detection, specify an MBLD25X500S and migrate from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
Size on the equal force: this bore delivers 206 N each way at 0.5 MPa. If you need less force, step down to the 20 mm bore (132 N each way). If you need more force, step up to the 32 mm bore (346 N each way). At 500 mm stroke, add external load guides to prevent side-load damage to the rod seals.
Upgrade checklist
- ✓ Order the MBLD25X500 (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 MBLD25X500 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500 FAQ
Yes, the MALD25X500 is discontinued. The exact drop-in replacement is the MBLD25X500, matching the 25 mm bore, 500 mm stroke, G1/8 port, and mounting. The MBLD upgrades the construction from threaded covers to a riveted rolling-packed body.
Because a rod exits both ends, both sides have the same annulus area, making push and pull force equal. The ratings are 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. Note that this non-standard 500 mm stroke exceeds the 300 mm standard limit, and this no-magnet SKU cannot accept a position sensor.
