This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X450-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X450-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 MALD25X450-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450-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 MBLD25X450-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450-S
The AirTAC MALD25X450-S is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends, yielding equal push and pull force of 206 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD25X450-S, matching the 25 mm bore, 450 mm stroke, G1/8 port, and M10x1.25 rod thread.
This 450 mm stroke exceeds the 300 mm standard limit, making it a made-to-order item requiring careful side-load management. The twin-rod design resists rotation and doubles the bearing load for guided sliding. The original threaded covers and CS1-M/DS1-M magnet switches are upgraded in the MBLD to a riveted rolling-packed body with CMSG/DMSG/EMSG sensors.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X450-S |
| Bore size | Ø25 mm |
| Stroke | 450 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 MBLD25X450-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 MBLD25X450-S matches these values.

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 MALD25X450-S Is Used
PCB Edge Conveyor
Drives a long-travel guided pallet in a PCB assembly line, using the 206 N equal force and twin rods to prevent chassis twist over the 450 mm span.
Textile Beam Indexer
Shifts a fabric beam laterally in a textile mill, relying on the anti-rotation properties of the double-rod layout to keep the material aligned.
Dual-Tool Dispenser
Mounts a secondary valve manifold on the rear rod of a packaging machine, using the rear-exiting shaft to carry tooling alongside the primary 289 N actuation.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450-S with MBLD25X450-S
To replace the MALD25X450-S, specify the MBLD25X450-S and confirm the G1/8 port, PT thread, FA/LB mounting (no back cover or SDB), and the -S magnet upgrade to CMSG/DMSG/EMSG switches. Size on the equal 206 N force at 0.5 MPa. If you need less force, step down to the 20 mm bore providing 132 N each way; if you need more, step up to the 32 mm bore providing 346 N each way. At 450 mm, use external guides to prevent rod binding and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD25X450-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 MBLD25X450-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450-S FAQ
Yes, the MALD25X450-S is discontinued. The exact drop-in replacement is the MBLD25X450-S, which matches the 25 mm bore, 450 mm stroke, G1/8 port, and M10x1.25 rod thread. You must upgrade your sensors from the old CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The twin rods exit both ends of the bore, meaning both sides have the same annulus area. The force is equal in both directions: 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. The cylinder uses a fixed rubber bumper, not an adjustable cushion.
