This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X85S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X85S 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 MALD25X85S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X85S 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 MBLD25X85S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X85S
The AirTAC MALD25X85S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 25mm bore, yielding equal push and pull force of 206 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD25X85S, matching the 85mm stroke, G1/8 port, and mounting footprint.
This twin-rod design resists rotation and doubles the bearing load for guided slides. The MALD uses threaded covers and a CS1-M / DS1-M magnet switch (the -S code), whereas the MBLD upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. It has a fixed rubber bumper, no back cover, and no SDB option.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X85S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X85S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X85S |
| Bore size | Ø25 mm |
| Stroke | 85 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 MBLD25X85S 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 MBLD25X85S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X85S Is Used
PCB Edge Routing Spindle
The twin rods prevent rotational drift on a Z-axis routing spindle, using the equal 206 N force to cleanly plunge and retract the 85mm stroke through rigid FR-4 fiberglass panels.
Textile Loom Takedown Cam
The rear rod carries a cam flag for timing, while the 85mm stroke shifts woven fabric layers precisely, relying on the double-bearing guidance to resist fabric pull-off torque.
Dual-End Pick-and-Place
A tool mounts on the front rod and a CS1-M sensor flag on the rear, using the 289 N force at 0.7 MPa to extract heavy plastic injection moulding cores without torsional binding.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X85S with MBLD25X85S
To replace the MALD25X85S with the MBLD25X85S, confirm the 25mm bore, 85mm stroke, G1/8 port, PT thread, and FA/LB mounting. Because it is a double-rod cylinder, there is no back-cover code or SDB; mount directly on the body. The -S magnet means you must upgrade your switches from the old CS1-M / DS1-M to the MBLD's CMSG / DMSG / EMSG family. Size strictly on the equal force of 206 N at 0.5 MPa. If you need less force, step down to the 20mm bore (132 N at 0.5 MPa); if you need more, step up to the 32mm bore (346 N at 0.5 MPa).
Upgrade checklist
- ✓ Order the MBLD25X85S (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 MBLD25X85S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X85S FAQ
Yes, the MALD25X85S is discontinued. The exact drop-in replacement is the MBLD25X85S, which matches the 25mm bore, 85mm stroke, G1/8 port, and FA/LB mounting. You will only need to update the magnet switches from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG family, as the MBLD uses a riveted rolling-packed body instead of threaded covers.
Because a rod exits both ends, the piston sees the same annulus area on both sides, making push and pull force equal. The full figure set for this 25mm bore is: 206 N push and 206 N pull at 0.5 MPa, 289 N push and 289 N pull at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. End-of-travel impact is softened by a fixed rubber bumper, which is not an adjustable cushion or a load-holding lock.
